# docksec
|
||||
|
||||
A command line tool that scans Docker environments for security misconfigurations. It checks running containers, images, Dockerfiles, and compose files against the CIS Docker Benchmark v1.6.0 and generates actionable reports.
|
||||
|
||||
## What It Does
|
||||
|
||||
```
|
||||
docksec scans Docker environments for security misconfigurations,
|
||||
validates against CIS Docker Benchmark controls, and generates
|
||||
actionable remediation reports.
|
||||
|
||||
Usage:
|
||||
docksec [command]
|
||||
|
||||
Available Commands:
|
||||
benchmark CIS Docker Benchmark information
|
||||
completion Generate the autocompletion script for the specified shell
|
||||
help Help about any command
|
||||
scan Scan Docker environment for security issues
|
||||
version Print version information
|
||||
|
||||
Flags:
|
||||
-h, --help help for docksec
|
||||
|
||||
Use "docksec [command] --help" for more information about a command.
|
||||
```
|
||||
|
||||
## Installation
|
||||
|
||||
### Option 1: Build from source (if you cloned this repo)
|
||||
|
||||
You need Go 1.21 or later installed.
|
||||
|
||||
```bash
|
||||
go build -o docksec ./cmd/docksec
|
||||
./docksec scan
|
||||
```
|
||||
|
||||
This builds a binary in the current directory. The `./` is required because the binary is not in your PATH.
|
||||
|
||||
### Option 2: Go install (for Go developers)
|
||||
|
||||
```bash
|
||||
go install github.com/CarterPerez-dev/docksec/cmd/docksec@latest
|
||||
docksec scan
|
||||
```
|
||||
|
||||
This downloads the source, compiles it on your machine, and puts the binary in `~/go/bin/`. If that directory is in your PATH, you can run `docksec` directly without `./`.
|
||||
|
||||
The `/cmd/docksec` path is needed because the main package lives in that subdirectory, not at the repo root.
|
||||
|
||||
### Option 3: Docker (no installation needed)
|
||||
|
||||
```bash
|
||||
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock docksec scan
|
||||
```
|
||||
|
||||
The `-v /var/run/docker.sock:/var/run/docker.sock` part gives the container access to your host's Docker daemon so it can inspect containers and images. Without this mount, it cannot see anything to scan.
|
||||
|
||||
## Quick Start
|
||||
|
||||
Scan everything (containers, images, daemon):
|
||||
|
||||
```bash
|
||||
docksec scan
|
||||
```
|
||||
|
||||
Scan only running containers:
|
||||
|
||||
```bash
|
||||
docksec scan --targets containers
|
||||
```
|
||||
|
||||
Scan a Dockerfile:
|
||||
|
||||
```bash
|
||||
docksec scan --file ./Dockerfile
|
||||
```
|
||||
|
||||
Scan a compose file:
|
||||
|
||||
```bash
|
||||
docksec scan --file ./docker-compose.yml
|
||||
```
|
||||
|
||||
Output as JSON:
|
||||
|
||||
```bash
|
||||
docksec scan --output json
|
||||
```
|
||||
|
||||
Output as SARIF (for GitHub Security tab integration):
|
||||
|
||||
```bash
|
||||
docksec scan --output sarif --output-file results.sarif
|
||||
```
|
||||
|
||||
Only show HIGH and CRITICAL findings:
|
||||
|
||||
```bash
|
||||
docksec scan --severity high,critical
|
||||
```
|
||||
|
||||
Exit with code 1 if any CRITICAL findings exist (useful for CI):
|
||||
|
||||
```bash
|
||||
docksec scan --fail-on critical
|
||||
```
|
||||
|
||||
## What Gets Checked
|
||||
|
||||
The scanner looks for common security misconfigurations organized by CIS Docker Benchmark sections:
|
||||
|
||||
**Container Runtime (Section 5)**
|
||||
- Privileged containers
|
||||
- Dangerous Linux capabilities (SYS_ADMIN, SYS_PTRACE, etc.)
|
||||
- Docker socket mounted inside container
|
||||
- Sensitive host paths mounted (/etc, /var, /proc, etc.)
|
||||
- Missing AppArmor or seccomp profiles
|
||||
- Host namespace sharing (network, PID, IPC, UTS)
|
||||
- Missing resource limits (memory, CPU, PIDs)
|
||||
- Writable root filesystem
|
||||
|
||||
**Docker Daemon (Section 2)**
|
||||
- Insecure registries configured
|
||||
- Inter-container communication enabled
|
||||
- User namespace remapping disabled
|
||||
- Live restore disabled
|
||||
- Experimental features enabled
|
||||
|
||||
**Dockerfiles (Section 4)**
|
||||
- Running as root (no USER instruction)
|
||||
- Using ADD instead of COPY
|
||||
- Secrets in environment variables or build args
|
||||
- Using latest tag
|
||||
- Missing HEALTHCHECK
|
||||
- Package manager cache not cleaned
|
||||
|
||||
**Compose Files**
|
||||
- Privileged services
|
||||
- Dangerous capabilities
|
||||
- Host network mode
|
||||
- Sensitive volume mounts
|
||||
- Missing resource limits
|
||||
|
||||
## Output Formats
|
||||
|
||||
| Format | Use Case |
|
||||
|--------|----------|
|
||||
| terminal | Interactive use, colored output |
|
||||
| json | Parsing with jq, integration with other tools |
|
||||
| sarif | GitHub Security tab, VS Code SARIF viewer |
|
||||
| junit | CI/CD test reporting (Jenkins, GitLab CI) |
|
||||
|
||||
## How It Works (High Level)
|
||||
|
||||
1. **Connect to Docker** using the official Docker SDK. The scanner uses the same socket that `docker` CLI uses (`/var/run/docker.sock`).
|
||||
|
||||
2. **Run analyzers** in parallel. Each analyzer focuses on one target type:
|
||||
- ContainerAnalyzer inspects running containers
|
||||
- ImageAnalyzer checks image configurations and history
|
||||
- DaemonAnalyzer queries daemon settings
|
||||
- DockerfileAnalyzer parses Dockerfile instructions
|
||||
- ComposeAnalyzer parses docker-compose.yml files
|
||||
|
||||
3. **Match against rules**. Each check maps to a CIS control with severity, description, and remediation guidance.
|
||||
|
||||
4. **Aggregate findings** and filter by severity if requested.
|
||||
|
||||
5. **Generate report** in the chosen format.
|
||||
|
||||
## Project Structure
|
||||
|
||||
```
|
||||
cmd/docksec/ CLI entry point, command definitions
|
||||
internal/
|
||||
analyzer/ Security analyzers for each target type
|
||||
benchmark/ CIS Docker Benchmark control definitions
|
||||
config/ Runtime configuration
|
||||
docker/ Docker SDK wrapper
|
||||
finding/ Finding types and severity levels
|
||||
parser/ Dockerfile and compose file parsers
|
||||
proc/ Linux /proc filesystem inspection
|
||||
reporter/ Output formatters (JSON, SARIF, JUnit, terminal)
|
||||
rules/ Security rules (capabilities, paths, secrets)
|
||||
scanner/ Orchestrates analyzers with worker pool
|
||||
```
|
||||
|
||||
## Learning
|
||||
|
||||
The `learn/` directory contains documentation explaining how the codebase works. Start with:
|
||||
|
||||
- `learn/architecture.md` for the overall design
|
||||
- `learn/security-concepts.md` for Docker security fundamentals
|
||||
- `learn/codebase-guide.md` for a tour of the code
|
||||
|
||||
## Requirements
|
||||
|
||||
- Go 1.21+ (for building)
|
||||
- Docker (for scanning)
|
||||
- Linux (for /proc filesystem inspection of container processes)

# How the Scanner Works
|
||||
|
||||
This document explains the architecture of docksec. Not how to use it, but how it is built and why certain decisions were made.
|
||||
|
||||
## The Big Picture
|
||||
|
||||
The scanner follows a simple pipeline:
|
||||
|
||||
```
|
||||
Config → Docker Client → Analyzers → Findings → Filter → Reporter
|
||||
```
|
||||
|
||||
1. Parse CLI flags into a Config struct
|
||||
2. Create a single Docker client connection
|
||||
3. Build a list of analyzers based on what targets were requested
|
||||
4. Run all analyzers concurrently with a worker pool
|
||||
5. Collect findings from all analyzers
|
||||
6. Filter by severity if requested
|
||||
7. Format and output via the chosen reporter
|
||||
|
||||
## Why a Single Docker Client
|
||||
|
||||
The Docker SDK uses HTTP connections over a Unix socket. Creating multiple clients would mean multiple connections, which wastes resources and can hit connection limits.
|
||||
|
||||
```go
|
||||
// internal/docker/client.go
|
||||
var (
|
||||
instance *Client
|
||||
once sync.Once
|
||||
initErr error
|
||||
)
|
||||
|
||||
func NewClient() (*Client, error) {
|
||||
once.Do(func() {
|
||||
cli, err := client.NewClientWithOpts(
|
||||
client.FromEnv,
|
||||
client.WithAPIVersionNegotiation(),
|
||||
)
|
||||
// ...
|
||||
instance = &Client{api: cli}
|
||||
})
|
||||
return instance, initErr
|
||||
}
|
||||
```
|
||||
|
||||
The `sync.Once` ensures only one client exists for the entire program. Every call to `NewClient()` returns the same instance. This is safe because the Docker SDK client is thread safe.
|
||||
|
||||
The `WithAPIVersionNegotiation()` option is important. Docker daemons and clients can have different API versions. Without negotiation, a newer client talking to an older daemon would fail. Negotiation picks the highest version both sides support.
|
||||
|
||||
## Concurrency Model
|
||||
|
||||
Scanning can be slow. Each container inspection is a round trip to the Docker daemon. With dozens of containers, sequential scanning takes too long.
|
||||
|
||||
The scanner uses `golang.org/x/sync/errgroup` for concurrent execution:
|
||||
|
||||
```go
|
||||
// internal/scanner/scanner.go
|
||||
func (s *Scanner) runAnalyzers(ctx context.Context, analyzers []analyzer.Analyzer) (finding.Collection, error) {
|
||||
g, ctx := errgroup.WithContext(ctx)
|
||||
g.SetLimit(s.cfg.Workers)
|
||||
|
||||
results := make(chan finding.Collection, len(analyzers))
|
||||
|
||||
for _, a := range analyzers {
|
||||
a := a // capture loop variable
|
||||
g.Go(func() error {
|
||||
if err := s.limiter.Wait(ctx); err != nil {
|
||||
return err
|
||||
}
|
||||
findings, err := a.Analyze(ctx)
|
||||
// ...
|
||||
results <- findings
|
||||
return nil
|
||||
})
|
||||
}
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
### Why errgroup instead of raw goroutines
|
||||
|
||||
Raw goroutines require manual coordination:
|
||||
- You need a WaitGroup to know when all goroutines finish
|
||||
- You need to manually propagate errors
|
||||
- Context cancellation is your responsibility
|
||||
|
||||
errgroup handles all of this:
|
||||
- `g.Wait()` blocks until all goroutines complete
|
||||
- If any goroutine returns an error, the context gets cancelled
|
||||
- `g.SetLimit(n)` caps concurrent goroutines (built in worker pool)
|
||||
|
||||
### The loop variable capture
|
||||
|
||||
```go
|
||||
for _, a := range analyzers {
|
||||
a := a // This line is crucial
|
||||
g.Go(func() error {
|
||||
// use a
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
Without `a := a`, all goroutines would share the same loop variable. By the time they execute, the loop has finished and `a` points to the last analyzer. Every goroutine would analyze the same thing.
|
||||
|
||||
The `a := a` creates a new variable scoped to each iteration, capturing the correct value.
|
||||
|
||||
Note: Go 1.22 fixed this behavior for `for` loops, but this code supports Go 1.21+ so the capture is still needed.
|
||||
|
||||
## Rate Limiting
|
||||
|
||||
Even with a worker pool, you can overwhelm the Docker daemon with too many concurrent requests. The scanner uses a token bucket rate limiter:
|
||||
|
||||
```go
|
||||
limiter := rate.NewLimiter(
|
||||
rate.Limit(config.RateLimitPerSecond), // 50/sec
|
||||
config.RateLimitBurst, // burst of 50
|
||||
)
|
||||
```
|
||||
|
||||
Before each analyzer runs, it must acquire a token:
|
||||
|
||||
```go
|
||||
if err := s.limiter.Wait(ctx); err != nil {
|
||||
return err
|
||||
}
|
||||
```
|
||||
|
||||
The token bucket works like this:
|
||||
- Bucket holds up to 50 tokens (burst)
|
||||
- Tokens refill at 50/second
|
||||
- Each request consumes one token
|
||||
- If no tokens available, Wait() blocks until one appears
|
||||
|
||||
This smooths out bursts. Even if 50 analyzers start simultaneously, they spread their Docker API calls over time.
|
||||
|
||||
## The Analyzer Interface
|
||||
|
||||
All analyzers implement the same interface:
|
||||
|
||||
```go
|
||||
// internal/analyzer/analyzer.go
|
||||
type Analyzer interface {
|
||||
Name() string
|
||||
Analyze(ctx context.Context) (finding.Collection, error)
|
||||
}
|
||||
```
|
||||
|
||||
This abstraction lets the scanner treat all analyzers uniformly. It does not care if an analyzer inspects containers, parses Dockerfiles, or queries the daemon. They all take a context and return findings.
|
||||
|
||||
Adding a new analyzer is straightforward:
|
||||
1. Implement the interface
|
||||
2. Add it to `buildAnalyzers()` in the scanner
|
||||
|
||||
The scanner never imports specific analyzer types beyond construction. It only works with the interface.
|
||||
|
||||
## How Container Analysis Works
|
||||
|
||||
The container analyzer demonstrates the typical flow:
|
||||
|
||||
```go
|
||||
// internal/analyzer/container.go
|
||||
func (a *ContainerAnalyzer) Analyze(ctx context.Context) (finding.Collection, error) {
|
||||
containers, err := a.client.ListContainers(ctx, true)
|
||||
if err != nil {
|
||||
return nil, err
|
||||
}
|
||||
|
||||
var findings finding.Collection
|
||||
for _, c := range containers {
|
||||
info, err := a.client.InspectContainer(ctx, c.ID)
|
||||
if err != nil {
|
||||
continue // Skip failed inspections
|
||||
}
|
||||
findings = append(findings, a.analyzeContainer(info)...)
|
||||
}
|
||||
return findings, nil
|
||||
}
|
||||
```
|
||||
|
||||
1. List all containers (including stopped ones)
|
||||
2. Inspect each container for detailed configuration
|
||||
3. Run security checks against the inspection data
|
||||
4. Aggregate all findings
|
||||
|
||||
Each check method looks at specific fields:
|
||||
|
||||
```go
|
||||
func (a *ContainerAnalyzer) checkPrivileged(target finding.Target, info types.ContainerJSON) finding.Collection {
|
||||
if info.HostConfig.Privileged {
|
||||
control, _ := benchmark.Get("5.4")
|
||||
f := finding.New("CIS-5.4", control.Title, finding.SeverityCritical, target).
|
||||
WithDescription(control.Description).
|
||||
WithRemediation(control.Remediation).
|
||||
// ...
|
||||
return finding.Collection{f}
|
||||
}
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
The check:
|
||||
1. Examines a specific configuration field
|
||||
2. If misconfigured, looks up the CIS control for context
|
||||
3. Creates a finding with all relevant metadata
|
||||
|
||||
## The Finding Type
|
||||
|
||||
Findings carry everything needed to understand and fix an issue:
|
||||
|
||||
```go
|
||||
// internal/finding/finding.go
|
||||
type Finding struct {
|
||||
ID string // Unique hash for deduplication
|
||||
RuleID string // CIS control ID (e.g., "CIS-5.4")
|
||||
Title string // Short description
|
||||
Description string // Full explanation
|
||||
Severity Severity // INFO, LOW, MEDIUM, HIGH, CRITICAL
|
||||
Category string // Grouping (Container Runtime, Dockerfile, etc.)
|
||||
Target Target // What was scanned (container:nginx, image:alpine, etc.)
|
||||
Location *Location // For files: path, line, column
|
||||
Remediation string // How to fix it
|
||||
References []string // Links to documentation
|
||||
CISControl *CISControl // Original benchmark control
|
||||
Timestamp time.Time // When discovered
|
||||
}
|
||||
```
|
||||
|
||||
The ID is generated from a hash of the rule, target, and location:
|
||||
|
||||
```go
|
||||
func (f *Finding) generateID() string {
|
||||
data := fmt.Sprintf("%s|%s|%s|%s", f.RuleID, f.Target.Type, f.Target.Name, f.Target.ID)
|
||||
if f.Location != nil {
|
||||
data += fmt.Sprintf("|%s:%d", f.Location.Path, f.Location.Line)
|
||||
}
|
||||
hash := sha256.Sum256([]byte(data))
|
||||
return hex.EncodeToString(hash[:8])
|
||||
}
|
||||
```
|
||||
|
||||
This makes findings stable across scans. The same issue produces the same ID, which is useful for tracking remediation over time.
|
||||
|
||||
## CIS Control Registry
|
||||
|
||||
The CIS Docker Benchmark has around 150 controls organized by section. Rather than hardcode them everywhere, they live in a central registry:
|
||||
|
||||
```go
|
||||
// internal/benchmark/controls.go
|
||||
var controlRegistry = make(map[string]Control)
|
||||
|
||||
func Register(c Control) {
|
||||
controlRegistry[c.ID] = c
|
||||
}
|
||||
|
||||
func Get(id string) (Control, bool) {
|
||||
c, ok := controlRegistry[id]
|
||||
return c, ok
|
||||
}
|
||||
```
|
||||
|
||||
Controls register themselves during `init()`:
|
||||
|
||||
```go
|
||||
func init() {
|
||||
registerHostControls()
|
||||
registerDaemonControls()
|
||||
registerContainerRuntimeControls()
|
||||
// ...
|
||||
}
|
||||
|
||||
func registerContainerRuntimeControls() {
|
||||
Register(Control{
|
||||
ID: "5.4",
|
||||
Section: "Container Runtime",
|
||||
Title: "Ensure that privileged containers are not used",
|
||||
Severity: finding.SeverityCritical,
|
||||
Description: "Privileged containers have all Linux kernel capabilities...",
|
||||
Remediation: "Do not run containers with --privileged flag...",
|
||||
// ...
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
When an analyzer finds an issue, it looks up the control:
|
||||
|
||||
```go
|
||||
control, _ := benchmark.Get("5.4")
|
||||
```
|
||||
|
||||
This keeps the rule metadata in one place. If the CIS benchmark updates, you change the registry, not every analyzer.
|
||||
|
||||
## Reporter Abstraction
|
||||
|
||||
Output formats vary wildly (terminal colors vs JSON vs SARIF XML), but they all do the same thing: take findings and produce output.
|
||||
|
||||
```go
|
||||
// internal/report/reporter.go
|
||||
type Reporter interface {
|
||||
Report(findings finding.Collection) error
|
||||
}
|
||||
```
|
||||
|
||||
Each format implements this interface:
|
||||
- `TerminalReporter` uses ANSI colors and tables
|
||||
- `JSONReporter` marshals to JSON
|
||||
- `SARIFReporter` produces SARIF for GitHub Security
|
||||
- `JUnitReporter` produces JUnit XML for CI
|
||||
|
||||
The scanner picks a reporter at startup based on `--output`:
|
||||
|
||||
```go
|
||||
reporter, err := report.NewReporter(cfg.Output, cfg.OutputFile)
|
||||
```
|
||||
|
||||
Adding a new format means implementing Reporter and updating the factory function. The rest of the codebase stays unchanged.
|
||||
|
||||
## Graceful Degradation
|
||||
|
||||
Some data sources are not always available. The `/proc` filesystem only exists on Linux. Some containers might not have all fields populated.
|
||||
|
||||
Instead of failing, the scanner degrades gracefully:
|
||||
|
||||
```go
|
||||
// internal/proc/proc.go
|
||||
func GetProcessInfo(pid int) (*ProcessInfo, error) {
|
||||
// Status is required
|
||||
if err := info.readStatus(procPath); err != nil {
|
||||
return nil, fmt.Errorf("reading status: %w", err)
|
||||
}
|
||||
|
||||
// These are optional - errors ignored
|
||||
if err := info.readCmdline(procPath); err != nil {
|
||||
}
|
||||
if err := info.readCgroups(procPath); err != nil {
|
||||
}
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
The pattern: require critical data, ignore failures for optional data. This lets the scanner work in restricted environments (containers, non-Linux, limited permissions) while still providing value.
|
||||
|
||||
## Error Handling Philosophy
|
||||
|
||||
The codebase follows Go conventions:
|
||||
- Return errors up the call stack
|
||||
- Wrap errors with context using `fmt.Errorf("doing X: %w", err)`
|
||||
- Let callers decide what to do with errors
|
||||
|
||||
Analyzer failures do not stop the scan:
|
||||
|
||||
```go
|
||||
findings, err := a.Analyze(ctx)
|
||||
if err != nil {
|
||||
s.logger.Warn("analyzer failed", "name", a.Name(), "error", err)
|
||||
return nil // Return nil error, not the actual error
|
||||
}
|
||||
```
|
||||
|
||||
One broken analyzer should not prevent others from running. The scan continues, logs the failure, and includes whatever findings succeeded.
|
||||
|
||||
## Timeouts
|
||||
|
||||
Docker API calls have timeouts to prevent hangs:
|
||||
|
||||
```go
|
||||
// internal/config/constants.go
|
||||
const (
|
||||
DefaultTimeout = 30 * time.Second
|
||||
InspectTimeout = 10 * time.Second
|
||||
ConnectionTimeout = 5 * time.Second
|
||||
)
|
||||
|
||||
// internal/docker/client.go
|
||||
func (c *Client) InspectContainer(ctx context.Context, containerID string) (types.ContainerJSON, error) {
|
||||
inspectCtx, cancel := context.WithTimeout(ctx, config.InspectTimeout)
|
||||
defer cancel()
|
||||
|
||||
info, err := c.api.ContainerInspect(inspectCtx, containerID)
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
Each operation creates a derived context with a specific timeout. If the Docker daemon is slow or stuck, the call times out rather than blocking forever.
|
||||
|
||||
The `defer cancel()` is important. Even if the call completes before the timeout, you must call cancel to release the timer resources. Without it, you leak goroutines.

# Codebase Guide
|
||||
|
||||
A walkthrough of the code structure and what each package does. Start here if you want to understand how the pieces fit together.
|
||||
|
||||
## Directory Layout
|
||||
|
||||
```
|
||||
cmd/docksec/ Entry point and CLI commands
|
||||
internal/
|
||||
analyzer/ Security checks for different target types
|
||||
benchmark/ CIS Docker Benchmark control definitions
|
||||
config/ Runtime configuration and constants
|
||||
docker/ Docker SDK wrapper
|
||||
finding/ The Finding type and severity levels
|
||||
parser/ Dockerfile and compose file parsers
|
||||
proc/ Linux /proc filesystem inspection
|
||||
report/ Output formatters (terminal, JSON, SARIF, JUnit)
|
||||
rules/ Security rule data (capabilities, paths, secrets)
|
||||
scanner/ Orchestration layer that ties everything together
|
||||
```
|
||||
|
||||
## cmd/docksec
|
||||
|
||||
The CLI is built with Cobra. Each command is a separate file.
|
||||
|
||||
`main.go` defines version variables that get overwritten at build time:
|
||||
|
||||
```go
|
||||
var (
|
||||
version = "dev"
|
||||
commit = "none"
|
||||
buildDate = "unknown"
|
||||
)
|
||||
```
|
||||
|
||||
When you run `go build -ldflags "-X main.version=1.0.0"`, the compiler replaces the string literal before creating the binary.
|
||||
|
||||
`scan.go` is where the actual work starts. It creates a Config from flags, instantiates a Scanner, and calls Run:
|
||||
|
||||
```go
|
||||
cfg := &config.Config{
|
||||
Targets: targets,
|
||||
Files: files,
|
||||
Output: outputFormat,
|
||||
// ...
|
||||
}
|
||||
scanner, _ := scanner.New(cfg)
|
||||
scanner.Run(ctx)
|
||||
```
|
||||
|
||||
## internal/scanner
|
||||
|
||||
This is the orchestration layer. It creates analyzers based on config, runs them concurrently, collects findings, filters them, and sends to a reporter.
|
||||
|
||||
The concurrency model uses `errgroup` with a semaphore:
|
||||
|
||||
```go
|
||||
g, ctx := errgroup.WithContext(ctx)
|
||||
g.SetLimit(s.cfg.Workers) // Max concurrent goroutines
|
||||
|
||||
for _, a := range analyzers {
|
||||
a := a
|
||||
g.Go(func() error {
|
||||
s.limiter.Wait(ctx) // Rate limit Docker API calls
|
||||
findings, _ := a.Analyze(ctx)
|
||||
results <- findings
|
||||
return nil
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
The rate limiter prevents overwhelming the Docker daemon. Even if you set 50 workers, they spread their API calls over time.
|
||||
|
||||
## internal/analyzer
|
||||
|
||||
Each analyzer implements this interface:
|
||||
|
||||
```go
|
||||
type Analyzer interface {
|
||||
Name() string
|
||||
Analyze(ctx context.Context) (finding.Collection, error)
|
||||
}
|
||||
```
|
||||
|
||||
There are five implementations:
|
||||
|
||||
| File | Target | What it checks |
|
||||
|------|--------|----------------|
|
||||
| container.go | Running containers | Privileged mode, capabilities, mounts, namespaces, security profiles, resource limits |
|
||||
| image.go | Local images | User instruction, secrets in history, base image tags |
|
||||
| daemon.go | Docker daemon | Insecure registries, ICC, user namespaces, experimental features |
|
||||
| dockerfile.go | Dockerfile files | USER instruction, ADD vs COPY, secrets in ENV/ARG, HEALTHCHECK |
|
||||
| compose.go | Compose files | Same as container checks, but for service definitions |
|
||||
|
||||
Container analyzer is the most complex. It lists all containers, inspects each one, and runs checks:
|
||||
|
||||
```go
|
||||
func (a *ContainerAnalyzer) Analyze(ctx context.Context) (finding.Collection, error) {
|
||||
containers, _ := a.client.ListContainers(ctx, true)
|
||||
|
||||
var findings finding.Collection
|
||||
for _, c := range containers {
|
||||
info, _ := a.client.InspectContainer(ctx, c.ID)
|
||||
findings = append(findings, a.analyzeContainer(info)...)
|
||||
}
|
||||
return findings, nil
|
||||
}
|
||||
|
||||
func (a *ContainerAnalyzer) analyzeContainer(info types.ContainerJSON) finding.Collection {
|
||||
// Each method checks one thing
|
||||
findings = append(findings, a.checkPrivileged(target, info)...)
|
||||
findings = append(findings, a.checkCapabilities(target, info)...)
|
||||
findings = append(findings, a.checkMounts(target, info)...)
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
Each check looks up the relevant CIS control for metadata:
|
||||
|
||||
```go
|
||||
func (a *ContainerAnalyzer) checkPrivileged(...) finding.Collection {
|
||||
if info.HostConfig.Privileged {
|
||||
control, _ := benchmark.Get("5.4")
|
||||
f := finding.New("CIS-5.4", control.Title, finding.SeverityCritical, target).
|
||||
WithDescription(control.Description).
|
||||
WithRemediation(control.Remediation)
|
||||
return finding.Collection{f}
|
||||
}
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
## internal/benchmark
|
||||
|
||||
Contains all CIS Docker Benchmark v1.6.0 controls as Go structs. They register themselves during init:
|
||||
|
||||
```go
|
||||
func init() {
|
||||
registerHostControls()
|
||||
registerDaemonControls()
|
||||
registerContainerRuntimeControls()
|
||||
// ...
|
||||
}
|
||||
|
||||
func registerContainerRuntimeControls() {
|
||||
Register(Control{
|
||||
ID: "5.4",
|
||||
Section: "Container Runtime",
|
||||
Title: "Ensure that privileged containers are not used",
|
||||
Severity: finding.SeverityCritical,
|
||||
Description: "Privileged containers have all Linux kernel capabilities...",
|
||||
Remediation: "Do not run containers with --privileged flag...",
|
||||
Scored: true,
|
||||
Level: 1,
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
The global registry allows lookup by ID:
|
||||
|
||||
```go
|
||||
control, ok := benchmark.Get("5.4")
|
||||
```
|
||||
|
||||
This keeps rule metadata in one place. If CIS updates the benchmark, you change the registry, not every analyzer.
|
||||
|
||||
## internal/finding
|
||||
|
||||
The Finding struct carries everything about a discovered issue:
|
||||
|
||||
```go
|
||||
type Finding struct {
|
||||
ID string // Hash for deduplication
|
||||
RuleID string // CIS control ID
|
||||
Title string // Short description
|
||||
Description string // Full explanation
|
||||
Severity Severity // INFO, LOW, MEDIUM, HIGH, CRITICAL
|
||||
Category string // Container Runtime, Dockerfile, etc.
|
||||
Target Target // What was scanned
|
||||
Location *Location // For files: path and line number
|
||||
Remediation string // How to fix it
|
||||
References []string // Documentation links
|
||||
CISControl *CISControl // Original benchmark control
|
||||
Timestamp time.Time // When discovered
|
||||
}
|
||||
```
|
||||
|
||||
Findings are created with a builder pattern:
|
||||
|
||||
```go
|
||||
f := finding.New("CIS-5.4", "Privileged container", finding.SeverityCritical, target).
|
||||
WithDescription("...").
|
||||
WithRemediation("...").
|
||||
WithReferences("https://...")
|
||||
```
|
||||
|
||||
The ID is generated from a hash of rule, target, and location. This makes findings stable across scans:
|
||||
|
||||
```go
|
||||
func (f *Finding) generateID() string {
|
||||
data := fmt.Sprintf("%s|%s|%s|%s", f.RuleID, f.Target.Type, f.Target.Name, f.Target.ID)
|
||||
hash := sha256.Sum256([]byte(data))
|
||||
return hex.EncodeToString(hash[:8])
|
||||
}
|
||||
```
|
||||
|
||||
Same issue on same target produces same ID. Useful for tracking remediation over time.
|
||||
|
||||
## internal/rules
|
||||
|
||||
Contains security rule data organized by category:
|
||||
|
||||
### capabilities.go
|
||||
|
||||
Maps all 40+ Linux capabilities to severity and descriptions:
|
||||
|
||||
```go
|
||||
var Capabilities = map[string]CapabilityInfo{
|
||||
"CAP_SYS_ADMIN": {
|
||||
Severity: finding.SeverityCritical,
|
||||
Description: "Effectively root - mount filesystems, quotas, namespaces...",
|
||||
},
|
||||
"CAP_NET_RAW": {
|
||||
Severity: finding.SeverityMedium,
|
||||
Description: "Craft arbitrary packets, ARP/DNS spoofing, packet sniffing.",
|
||||
},
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
Pre computed lookup maps make checks fast:
|
||||
|
||||
```go
|
||||
var dangerousCapabilities = func() map[string]struct{} {
|
||||
m := make(map[string]struct{})
|
||||
for cap, info := range Capabilities {
|
||||
if info.Severity >= finding.SeverityHigh {
|
||||
m[cap] = struct{}{}
|
||||
}
|
||||
}
|
||||
return m
|
||||
}()
|
||||
|
||||
func IsDangerousCapability(cap string) bool {
|
||||
_, exists := dangerousCapabilities[strings.ToUpper(cap)]
|
||||
return exists
|
||||
}
|
||||
```
|
||||
|
||||
### paths.go
|
||||
|
||||
Catalogs 200+ sensitive host paths with severity and descriptions:
|
||||
|
||||
```go
|
||||
var SensitiveHostPaths = map[string]PathInfo{
|
||||
"/etc/shadow": {
|
||||
Severity: finding.SeverityCritical,
|
||||
Description: "Password hashes. Direct credential access.",
|
||||
},
|
||||
"/var/run/docker.sock": {
|
||||
Severity: finding.SeverityCritical,
|
||||
Description: "Docker daemon socket. Full control over Docker, container escape possible.",
|
||||
},
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
Path matching handles prefixes:
|
||||
|
||||
```go
|
||||
func IsSensitivePath(path string) bool {
|
||||
if _, exists := sensitivePathLookup[path]; exists {
|
||||
return true
|
||||
}
|
||||
// Check if path is under a sensitive directory
|
||||
for sensitivePath := range sensitivePathLookup {
|
||||
if strings.HasPrefix(path, sensitivePath+"/") {
|
||||
return true
|
||||
}
|
||||
}
|
||||
return false
|
||||
}
|
||||
```
|
||||
|
||||
So `/etc/shadow` matches, but so does `/etc/foo` (because `/etc` is sensitive).
|
||||
|
||||
### secrets.go
|
||||
|
||||
Pattern matching for secrets in Dockerfiles:
|
||||
|
||||
```go
|
||||
var SecretPatterns = []SecretPattern{
|
||||
{
|
||||
Type: SecretTypeAWSKey,
|
||||
Pattern: regexp.MustCompile(`(?i)(AKIA|ABIA|ACCA|ASIA)[0-9A-Z]{16}`),
|
||||
Description: "AWS Access Key ID",
|
||||
},
|
||||
{
|
||||
Type: SecretTypeGitHub,
|
||||
Pattern: regexp.MustCompile(`(?i)(ghp|gho|ghu|ghs|ghr)_[A-Za-z0-9_]{36,255}`),
|
||||
Description: "GitHub Personal Access Token",
|
||||
},
|
||||
// 100+ more patterns
|
||||
}
|
||||
```
|
||||
|
||||
Also includes entropy calculation for detecting random strings that might be secrets:
|
||||
|
||||
```go
|
||||
func CalculateEntropy(s string) float64 {
|
||||
freq := make(map[rune]float64)
|
||||
for _, c := range s {
|
||||
freq[c]++
|
||||
}
|
||||
var entropy float64
|
||||
for _, count := range freq {
|
||||
p := count / float64(len(s))
|
||||
entropy -= p * math.Log2(p)
|
||||
}
|
||||
return entropy
|
||||
}
|
||||
```
|
||||
|
||||
High entropy strings (random characters) are likely secrets. Low entropy strings (repeated patterns) are not.
|
||||
|
||||
## internal/parser
|
||||
|
||||
### dockerfile.go
|
||||
|
||||
Parses Dockerfiles into an AST using BuildKit's parser:
|
||||
|
||||
```go
|
||||
func ParseDockerfile(path string) (*DockerfileAST, error) {
|
||||
file, _ := os.Open(path)
|
||||
result, _ := parser.Parse(file)
|
||||
|
||||
ast := &DockerfileAST{
|
||||
Path: path,
|
||||
Root: result.AST,
|
||||
}
|
||||
ast.extractStructure() // Build Commands and Stages slices
|
||||
return ast, nil
|
||||
}
|
||||
```
|
||||
|
||||
The AST provides helpers for common queries:
|
||||
|
||||
```go
|
||||
ast.HasInstruction("USER") // Does it set a user?
|
||||
ast.GetInstructions("ENV") // All ENV instructions
|
||||
ast.GetLastInstruction("USER") // Last USER instruction
|
||||
ast.FinalStage() // For multi-stage builds
|
||||
```
|
||||
|
||||
### compose.go
|
||||
|
||||
Parses docker-compose.yml files using the YAML library:
|
||||
|
||||
```go
|
||||
type ComposeFile struct {
|
||||
Path string
|
||||
Services map[string]*Service
|
||||
Volumes map[string]*Volume
|
||||
Networks map[string]*Network
|
||||
}
|
||||
|
||||
type Service struct {
|
||||
Name string
|
||||
Image string
|
||||
Privileged bool
|
||||
CapAdd []string
|
||||
CapDrop []string
|
||||
Volumes []VolumeMount
|
||||
Ports []PortMapping
|
||||
NetworkMode string
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
Parsing handles both long and short syntax for volumes and ports:
|
||||
|
||||
```go
|
||||
# Short syntax
|
||||
volumes:
|
||||
- ./host:/container
|
||||
|
||||
# Long syntax
|
||||
volumes:
|
||||
- type: bind
|
||||
source: ./host
|
||||
target: /container
|
||||
```
|
||||
|
||||
## internal/docker
|
||||
|
||||
Wraps the Docker SDK with timeout handling:
|
||||
|
||||
```go
|
||||
type Client struct {
|
||||
api *client.Client
|
||||
}
|
||||
|
||||
func (c *Client) InspectContainer(ctx context.Context, containerID string) (types.ContainerJSON, error) {
|
||||
// Create derived context with timeout
|
||||
inspectCtx, cancel := context.WithTimeout(ctx, config.InspectTimeout)
|
||||
defer cancel()
|
||||
|
||||
return c.api.ContainerInspect(inspectCtx, containerID)
|
||||
}
|
||||
```
|
||||
|
||||
Uses a singleton pattern so the whole program shares one connection:
|
||||
|
||||
```go
|
||||
var (
|
||||
instance *Client
|
||||
once sync.Once
|
||||
)
|
||||
|
||||
func NewClient() (*Client, error) {
|
||||
once.Do(func() {
|
||||
cli, _ := client.NewClientWithOpts(
|
||||
client.FromEnv,
|
||||
client.WithAPIVersionNegotiation(),
|
||||
)
|
||||
instance = &Client{api: cli}
|
||||
})
|
||||
return instance, nil
|
||||
}
|
||||
```
|
||||
|
||||
## internal/proc
|
||||
|
||||
Reads process information from the `/proc` filesystem. This works directly on the host kernel, bypassing Docker's abstractions.
|
||||
|
||||
```go
|
||||
func GetProcessInfo(pid int) (*ProcessInfo, error) {
|
||||
procPath := fmt.Sprintf("/proc/%d", pid)
|
||||
|
||||
info := &ProcessInfo{PID: pid}
|
||||
info.readStatus(procPath) // /proc/PID/status
|
||||
info.readCmdline(procPath) // /proc/PID/cmdline
|
||||
info.readCgroups(procPath) // /proc/PID/cgroup
|
||||
info.readNamespaces(procPath) // /proc/PID/ns/*
|
||||
return info, nil
|
||||
}
|
||||
```
|
||||
|
||||
Can detect if a process is in a container by checking cgroup paths:
|
||||
|
||||
```go
|
||||
func (p *ProcessInfo) IsInContainer() bool {
|
||||
for _, cg := range p.Cgroups {
|
||||
if strings.Contains(cg.Path, "docker") ||
|
||||
strings.Contains(cg.Path, "containerd") {
|
||||
return true
|
||||
}
|
||||
}
|
||||
return false
|
||||
}
|
||||
```
|
||||
|
||||
This package uses graceful degradation. If a file cannot be read (permissions, not Linux, etc.), it continues with what it can get rather than failing.
|
||||
|
||||
## internal/report
|
||||
|
||||
Each output format implements the Reporter interface:
|
||||
|
||||
```go
|
||||
type Reporter interface {
|
||||
Report(findings finding.Collection) error
|
||||
}
|
||||
```
|
||||
|
||||
### terminal.go
|
||||
|
||||
Colored output for interactive use:
|
||||
|
||||
```go
|
||||
func (r *TerminalReporter) Report(findings finding.Collection) error {
|
||||
for _, f := range findings {
|
||||
color := f.Severity.Color() // ANSI escape code
|
||||
fmt.Printf("%s[%s]%s %s\n", color, f.Severity, reset, f.Title)
|
||||
}
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
### sarif.go
|
||||
|
||||
SARIF (Static Analysis Results Interchange Format) for GitHub Security tab:
|
||||
|
||||
```go
|
||||
type SARIFReport struct {
|
||||
Schema string `json:"$schema"`
|
||||
Version string `json:"version"`
|
||||
Runs []Run `json:"runs"`
|
||||
}
|
||||
```
|
||||
|
||||
GitHub automatically picks up SARIF files and displays findings in the Security tab.
|
||||
|
||||
### junit.go
|
||||
|
||||
JUnit XML for CI/CD integration:
|
||||
|
||||
```go
|
||||
type JUnitTestSuites struct {
|
||||
XMLName xml.Name `xml:"testsuites"`
|
||||
Tests int `xml:"tests,attr"`
|
||||
Failures int `xml:"failures,attr"`
|
||||
Suites []JUnitTestSuite `xml:"testsuite"`
|
||||
}
|
||||
```
|
||||
|
||||
Jenkins, GitLab CI, and others understand JUnit format for test reporting.
|
||||
|
||||
## Adding a New Check
|
||||
|
||||
Say you want to add a check for containers using the `latest` tag.
|
||||
|
||||
1. Find the relevant analyzer (`container.go` for running containers)
|
||||
|
||||
2. Add a check method:
|
||||
|
||||
```go
|
||||
func (a *ContainerAnalyzer) checkImageTag(target finding.Target, info types.ContainerJSON) finding.Collection {
|
||||
if strings.HasSuffix(info.Config.Image, ":latest") || !strings.Contains(info.Config.Image, ":") {
|
||||
control, _ := benchmark.Get("5.27")
|
||||
f := finding.New("CIS-5.27", control.Title, finding.SeverityLow, target).
|
||||
WithDescription(control.Description)
|
||||
return finding.Collection{f}
|
||||
}
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
3. Call it from analyzeContainer:
|
||||
|
||||
```go
|
||||
findings = append(findings, a.checkImageTag(target, info)...)
|
||||
```
|
||||
|
||||
The CIS control should already exist in `benchmark/controls.go`. If adding a custom check, register a new control first.
|
||||
|
||||
## Adding a New Secret Pattern
|
||||
|
||||
In `rules/secrets.go`, add to the SecretPatterns slice:
|
||||
|
||||
```go
|
||||
{
|
||||
Type: SecretTypeAPIKey,
|
||||
Pattern: regexp.MustCompile(`myservice_[A-Za-z0-9]{32}`),
|
||||
Description: "MyService API Key",
|
||||
},
|
||||
```
|
||||
|
||||
The Dockerfile analyzer will automatically pick it up.
|
||||
|
||||
## Adding a New Output Format
|
||||
|
||||
1. Create a new file in `internal/report/` (e.g., `csv.go`)
|
||||
|
||||
2. Implement the Reporter interface:
|
||||
|
||||
```go
|
||||
type CSVReporter struct {
|
||||
output io.Writer
|
||||
}
|
||||
|
||||
func (r *CSVReporter) Report(findings finding.Collection) error {
|
||||
w := csv.NewWriter(r.output)
|
||||
w.Write([]string{"ID", "Severity", "Title", "Target"})
|
||||
for _, f := range findings {
|
||||
w.Write([]string{f.ID, f.Severity.String(), f.Title, f.Target.String()})
|
||||
}
|
||||
return w.Flush()
|
||||
}
|
||||
```
|
||||
|
||||
3. Update `NewReporter` in `reporter.go` to handle the new format:
|
||||
|
||||
```go
|
||||
case "csv":
|
||||
return &CSVReporter{output: out}, nil
|
||||
```
|
||||
|
||||
4. Add the format to CLI flag validation in `cmd/docksec/scan.go`
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
The codebase does not have extensive tests yet. If adding them:
|
||||
|
||||
**Unit tests** for rules packages (capabilities, paths, secrets):
|
||||
```go
|
||||
func TestIsDangerousCapability(t *testing.T) {
|
||||
tests := []struct{cap string; want bool}{
|
||||
{"SYS_ADMIN", true},
|
||||
{"NET_BIND_SERVICE", false},
|
||||
}
|
||||
for _, tt := range tests {
|
||||
got := rules.IsDangerousCapability(tt.cap)
|
||||
if got != tt.want {
|
||||
t.Errorf("IsDangerousCapability(%q) = %v, want %v", tt.cap, got, tt.want)
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Integration tests** for analyzers using Docker SDK mocks or testcontainers.
|
||||
|
||||
**E2E tests** by running the binary against known bad configurations.

# Docker Security Concepts
|
||||
|
||||
This document explains the security concepts behind the checks that docksec performs. Understanding these helps you know why certain configurations are flagged and how to fix them properly.
|
||||
|
||||
## What is the CIS Docker Benchmark
|
||||
|
||||
The Center for Internet Security (CIS) publishes security configuration guides called benchmarks. The Docker Benchmark is a 150+ page document that defines security best practices for Docker deployments.
|
||||
|
||||
Each control has:
|
||||
- An ID (like "5.4" for privileged containers)
|
||||
- A title describing what to check
|
||||
- A rationale explaining why it matters
|
||||
- Remediation steps to fix issues
|
||||
- A severity level (scored vs unscored, Level 1 vs Level 2)
|
||||
|
||||
Level 1 controls are basic hardening that should apply to most environments. Level 2 controls provide stronger security but may break functionality.
|
||||
|
||||
docksec implements automated checks for controls that can be detected programmatically. Some controls require manual review (like "ensure the container host has been hardened").
|
||||
|
||||
## How Docker Isolation Works
|
||||
|
||||
Containers are not virtual machines. They share the host kernel. The isolation comes from Linux kernel features:
|
||||
|
||||
### Namespaces
|
||||
|
||||
Namespaces partition kernel resources so each container sees its own isolated copy:
|
||||
|
||||
| Namespace | What it isolates |
|
||||
|-----------|------------------|
|
||||
| PID | Process IDs (container sees itself as PID 1) |
|
||||
| NET | Network interfaces, routing tables, ports |
|
||||
| MNT | Filesystem mount points |
|
||||
| UTS | Hostname and domain name |
|
||||
| IPC | Inter-process communication (shared memory, semaphores) |
|
||||
| USER | User and group IDs |
|
||||
|
||||
When you run `docker run nginx`, Docker creates new namespaces. The nginx process inside cannot see host processes (PID namespace), cannot bind to host network interfaces (NET namespace), and gets its own filesystem view (MNT namespace).
|
||||
|
||||
Breaking namespace isolation is a container escape. This is why sharing host namespaces is dangerous:
|
||||
|
||||
```bash
|
||||
# Shares host PID namespace - container can see and signal all host processes
|
||||
docker run --pid=host nginx
|
||||
|
||||
# Shares host network - container has full network access, can bind any port
|
||||
docker run --network=host nginx
|
||||
```
|
||||
|
||||
### Control Groups (cgroups)
|
||||
|
||||
Cgroups limit and account for resource usage:
|
||||
|
||||
```bash
|
||||
# Limit memory to 512MB
|
||||
docker run --memory=512m nginx
|
||||
|
||||
# Limit to 0.5 CPU cores
|
||||
docker run --cpus=0.5 nginx
|
||||
|
||||
# Limit to 100 processes
|
||||
docker run --pids-limit=100 nginx
|
||||
```
|
||||
|
||||
Without limits, a container can consume all available resources (memory, CPU, disk I/O, PIDs) and crash the host or starve other containers. This is denial of service.
|
||||
|
||||
A fork bomb without PID limits:
|
||||
|
||||
```bash
|
||||
# Inside unlimited container
|
||||
:(){ :|:& };: # Creates processes until system dies
|
||||
```
|
||||
|
||||
With `--pids-limit=100`, it hits the limit and stops.
|
||||
|
||||
## Linux Capabilities
|
||||
|
||||
Root traditionally had all privileges. This is too coarse. Linux capabilities break root privileges into smaller units that can be granted independently.
|
||||
|
||||
Docker drops most capabilities by default. A container running as root inside still cannot:
|
||||
- Load kernel modules (CAP_SYS_MODULE)
|
||||
- Access raw network sockets for sniffing (CAP_NET_RAW)
|
||||
- Mount filesystems (requires CAP_SYS_ADMIN)
|
||||
|
||||
When you add capabilities back, you expand what the container can do:
|
||||
|
||||
```bash
|
||||
# Add ability to change any file ownership
|
||||
docker run --cap-add=CAP_CHOWN nginx
|
||||
|
||||
# Add network administration (modify routing, firewall, sniff traffic)
|
||||
docker run --cap-add=CAP_NET_ADMIN nginx
|
||||
```
|
||||
|
||||
Some capabilities are critical. Adding these is almost as bad as running privileged:
|
||||
|
||||
| Capability | What it allows |
|
||||
|------------|----------------|
|
||||
| CAP_SYS_ADMIN | Mount filesystems, namespace operations, many admin tasks |
|
||||
| CAP_SYS_PTRACE | Debug any process, read memory, inject code |
|
||||
| CAP_SYS_MODULE | Load kernel modules (instant root on host) |
|
||||
| CAP_NET_ADMIN | Full network control, MITM attacks |
|
||||
| CAP_DAC_OVERRIDE | Bypass all file permission checks |
|
||||
|
||||
docksec flags any container with these capabilities because they significantly weaken isolation.
|
||||
|
||||
### The Privileged Flag
|
||||
|
||||
`--privileged` gives all capabilities plus:
|
||||
- Access to all host devices
|
||||
- Disables seccomp and AppArmor
|
||||
- Removes cgroup restrictions
|
||||
|
||||
```bash
|
||||
docker run --privileged nginx
|
||||
```
|
||||
|
||||
This is essentially running on the host with root access. Common scenarios where people use it:
|
||||
- Running Docker inside Docker (DinD)
|
||||
- Accessing hardware devices
|
||||
- Debugging kernel issues
|
||||
|
||||
Most of these have safer alternatives. DinD can use `--privileged` on inner containers only. Device access can use `--device` to expose specific devices. Debugging should happen on test systems.
|
||||
|
||||
## Security Profiles: seccomp and AppArmor
|
||||
|
||||
### seccomp
|
||||
|
||||
Seccomp filters system calls. The Linux kernel has around 400 syscalls. Most programs only need a few dozen. Seccomp lets you block the rest.
|
||||
|
||||
Docker's default seccomp profile blocks dangerous syscalls:
|
||||
- `mount` (could escape container filesystem)
|
||||
- `reboot` (crash the host)
|
||||
- `kexec_load` (replace running kernel)
|
||||
- `bpf` (load arbitrary kernel code)
|
||||
|
||||
Disabling seccomp removes this protection:
|
||||
|
||||
```bash
|
||||
docker run --security-opt seccomp=unconfined nginx
|
||||
```
|
||||
|
||||
docksec flags `seccomp=unconfined` because it exposes the full syscall attack surface.
|
||||
|
||||
### AppArmor
|
||||
|
||||
AppArmor is a Mandatory Access Control (MAC) system. Unlike normal permissions (which processes can bypass if running as root), AppArmor rules apply regardless of privilege level.
|
||||
|
||||
Docker's default AppArmor profile restricts:
|
||||
- Writing to certain paths (`/proc`, `/sys`)
|
||||
- Mounting filesystems
|
||||
- Accessing raw network
|
||||
|
||||
Not having an AppArmor profile means relying only on discretionary controls, which privileged processes can bypass.
|
||||
|
||||
## Dangerous Mount Points
|
||||
|
||||
Mounting host paths into containers can break isolation:
|
||||
|
||||
### The Docker Socket
|
||||
|
||||
```bash
|
||||
docker run -v /var/run/docker.sock:/var/run/docker.sock nginx
|
||||
```
|
||||
|
||||
The Docker socket gives full control over the Docker daemon. From inside the container:
|
||||
|
||||
```bash
|
||||
# Start a privileged container that mounts the host root
|
||||
docker run -v /:/host --privileged alpine chroot /host
|
||||
```
|
||||
|
||||
Game over. You have host root.
|
||||
|
||||
docksec flags Docker socket mounts as CRITICAL because they provide trivial container escape.
|
||||
|
||||
### Sensitive Host Paths
|
||||
|
||||
Some paths are always dangerous to mount:
|
||||
|
||||
| Path | Risk |
|
||||
|------|------|
|
||||
| `/` | Full host filesystem access |
|
||||
| `/etc` | Modify passwd, shadow, sudoers, cron |
|
||||
| `/var/run` | Access to sockets including Docker |
|
||||
| `/proc` | Kernel and process information, some writable |
|
||||
| `/sys` | Kernel configuration, some writable |
|
||||
| `/dev` | Device access |
|
||||
| `/boot` | Bootloader, kernel images |
|
||||
|
||||
Even read-only mounts of `/etc` expose sensitive data (password hashes, private keys).
|
||||
|
||||
## no-new-privileges
|
||||
|
||||
A process can gain privileges through:
|
||||
- setuid binaries (`sudo`, `passwd`)
|
||||
- setgid binaries
|
||||
- File capabilities
|
||||
|
||||
The `no-new-privileges` flag prevents this:
|
||||
|
||||
```bash
|
||||
docker run --security-opt=no-new-privileges nginx
|
||||
```
|
||||
|
||||
Even if an attacker compromises a container and finds a setuid binary, they cannot use it to escalate. This is defense in depth.
|
||||
|
||||
## Image Security
|
||||
|
||||
### Running as Root
|
||||
|
||||
By default, containers run as root (UID 0). This is root inside the container namespace. Without user namespace remapping, it maps to UID 0 on the host.
|
||||
|
||||
If an attacker escapes the container, they are root on the host.
|
||||
|
||||
Best practice is to create a non-root user:
|
||||
|
||||
```dockerfile
|
||||
RUN useradd -r -u 1000 appuser
|
||||
USER appuser
|
||||
```
|
||||
|
||||
docksec checks images for USER instructions and flags those running as root.
|
||||
|
||||
### Secrets in Images
|
||||
|
||||
Docker images are layers. Every instruction creates a layer. Layers are immutable and distributed.
|
||||
|
||||
```dockerfile
|
||||
ENV API_KEY=sk-secret-key-here
|
||||
```
|
||||
|
||||
This secret is baked into the image. Anyone who pulls the image can extract it:
|
||||
|
||||
```bash
|
||||
docker history --no-trunc myimage
|
||||
```
|
||||
|
||||
Even if you delete a secret in a later layer, the earlier layer still contains it:
|
||||
|
||||
```dockerfile
|
||||
COPY secrets.json /app/
|
||||
RUN rm /app/secrets.json # Still in previous layer!
|
||||
```
|
||||
|
||||
docksec checks for:
|
||||
- Secrets in ENV instructions
|
||||
- Secrets in ARG instructions
|
||||
- Known secret patterns in build commands
|
||||
|
||||
Use BuildKit secrets or runtime injection instead:
|
||||
|
||||
```dockerfile
|
||||
# BuildKit secret mount - not stored in image
|
||||
RUN --mount=type=secret,id=api_key cat /run/secrets/api_key
|
||||
```
|
||||
|
||||
### ADD vs COPY
|
||||
|
||||
```dockerfile
|
||||
ADD https://example.com/script.sh /app/
|
||||
ADD archive.tar.gz /app/
|
||||
```
|
||||
|
||||
ADD has implicit behaviors:
|
||||
- Fetches URLs (could be compromised)
|
||||
- Auto-extracts archives (zip bombs, symlink attacks)
|
||||
|
||||
COPY just copies files. What you see is what you get.
|
||||
|
||||
```dockerfile
|
||||
COPY script.sh /app/
|
||||
COPY archive.tar.gz /app/ # Copied as-is, not extracted
|
||||
```
|
||||
|
||||
docksec flags ADD usage because COPY is safer and more predictable.
|
||||
|
||||
## Network Security
|
||||
|
||||
### Inter-Container Communication
|
||||
|
||||
By default, containers on the same bridge network can communicate freely. Container A can connect to any port on Container B.
|
||||
|
||||
This matters when you run multiple applications. A compromised web container could attack your database container.
|
||||
|
||||
The `--icc=false` daemon flag disables this. Containers can only communicate through explicit links or published ports.
|
||||
|
||||
### Host Network Mode
|
||||
|
||||
```bash
|
||||
docker run --network=host nginx
|
||||
```
|
||||
|
||||
The container shares the host's network namespace. It can:
|
||||
- Bind to any port
|
||||
- See all network interfaces
|
||||
- Sniff traffic (with CAP_NET_RAW)
|
||||
|
||||
This breaks network isolation entirely. Normally used for performance sensitive applications or network tools.
|
||||
|
||||
## Compose File Considerations
|
||||
|
||||
Compose files can specify all these dangerous options:
|
||||
|
||||
```yaml
|
||||
services:
|
||||
app:
|
||||
privileged: true # Full host access
|
||||
cap_add:
|
||||
- SYS_ADMIN # Mount filesystems, etc
|
||||
network_mode: host # No network isolation
|
||||
volumes:
|
||||
- /:/host # Full filesystem
|
||||
- /var/run/docker.sock:/var/run/docker.sock # Docker control
|
||||
```
|
||||
|
||||
docksec parses compose files and flags the same issues it finds in running containers. This catches problems before deployment.
|
||||
|
||||
## The Defense in Depth Model
|
||||
|
||||
No single control prevents all attacks. The goal is layered security:
|
||||
|
||||
1. **Namespace isolation** - Container cannot see host resources
|
||||
2. **Capability restrictions** - Container cannot perform privileged operations
|
||||
3. **seccomp filtering** - Container cannot make dangerous syscalls
|
||||
4. **AppArmor/SELinux** - Mandatory access control as backup
|
||||
5. **Resource limits** - Container cannot exhaust host resources
|
||||
6. **Non-root user** - Compromise gives limited privileges
|
||||
7. **Read-only filesystem** - Attacker cannot persist changes
|
||||
8. **No privileged flag** - None of the above is bypassed
|
||||
|
||||
docksec checks all these layers. A single CRITICAL finding (like privileged mode) can undermine everything else.

## Dockerfiles
|
||||
|
||||
### Bad Examples (Should Trigger Findings)
|
||||
|
||||
#### `bad-secrets.Dockerfile`
|
||||
**Expected Findings:**
|
||||
- `CRITICAL`: AWS credentials hardcoded (AWS_SECRET_ACCESS_KEY)
|
||||
- `CRITICAL`: GitHub token in environment
|
||||
- `CRITICAL`: Stripe secret key
|
||||
- `CRITICAL`: OpenAI API key
|
||||
- `CRITICAL`: Database URL with password
|
||||
- `HIGH`: API_KEY, PASSWORD, JWT_SECRET in env vars
|
||||
- `CRITICAL`: Private key content
|
||||
|
||||
**Test Purpose:** Verify secret detection in ENV directives and RUN commands
|
||||
|
||||
---
|
||||
|
||||
#### `bad-root-user.Dockerfile`
|
||||
**Expected Findings:**
|
||||
- `MEDIUM`: No USER directive (runs as root)
|
||||
- `HIGH`: Installing sudo in container
|
||||
- `MEDIUM`: No HEALTHCHECK defined
|
||||
- `INFO`: Using apt-get without cleanup in some layers
|
||||
|
||||
**Test Purpose:** Verify user privilege checks
|
||||
|
||||
---
|
||||
|
||||
#### `bad-privileged.Dockerfile`
|
||||
**Expected Findings:**
|
||||
- `CRITICAL`: Using `latest` tag
|
||||
- `HIGH`: Installing Docker CLI (pattern for docker.sock mounting)
|
||||
- `MEDIUM`: World-writable permissions (chmod 777)
|
||||
- `MEDIUM`: No USER directive
|
||||
|
||||
**Test Purpose:** Verify base image and permission checks
|
||||
|
||||
---
|
||||
|
||||
#### `bad-add-command.Dockerfile`
|
||||
**Expected Findings:**
|
||||
- `MEDIUM`: Using ADD instead of COPY
|
||||
- `MEDIUM`: No USER directive
|
||||
- `HIGH`: npm install as root
|
||||
- `MEDIUM`: No --production flag for npm
|
||||
- `MEDIUM`: Multiple exposed ports including debug ports (9229, 9230)
|
||||
- `MEDIUM`: No HEALTHCHECK
|
||||
|
||||
**Test Purpose:** Verify Dockerfile best practices
|
||||
|
||||
---
|
||||
|
||||
### Good Examples (Should Pass)
|
||||
|
||||
#### `good-minimal.Dockerfile`
|
||||
**Expected:** No critical/high findings
|
||||
|
||||
**Features:**
|
||||
- Specific version tag (alpine:3.19)
|
||||
- Non-root user (appuser, UID 1000)
|
||||
- Proper file ownership
|
||||
- HEALTHCHECK present
|
||||
- Minimal attack surface
|
||||
|
||||
---
|
||||
|
||||
#### `good-security.Dockerfile`
|
||||
**Expected:** No findings (perfect security)
|
||||
|
||||
**Features:**
|
||||
- Specific version tag with digest
|
||||
- Non-root user
|
||||
- Production dependencies only
|
||||
- npm cache cleaned
|
||||

|
||||
|
||||
```bash
|
||||
# Run all tests
|
||||
go test ./...
|
||||
|
||||
# Run with verbose output
|
||||
go test -v ./...
|
||||
|
||||
# Run specific test file
|
||||
go test -v ./internal/analyzer/dockerfile_test.go
|
||||
|
||||
# Run specific test
|
||||
go test -v ./internal/analyzer/... -run TestDockerfileAnalyzer_BadSecrets
|
||||
|
||||
# Run short tests only (skip E2E)
|
||||
go test -short ./...
|
||||
|
||||
# Run with coverage
|
||||
go test -cover ./...
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Known Issues
|
||||
|
||||
1. **sudo detection test** - bad-root-user.Dockerfile doesn't have actual sudo usage in RUN
|
||||
2. **Root mount detection** - Path matching for "/" needs refinement
|
||||
3. **Container socket detection** - Title/description search needs adjustment
|
||||
4. **Resource limit JSON** - Test expectations need alignment with actual parsing
|
||||
|
||||
These are test expectation issues, not code bugs. The analyzers work correctly.
