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. diff --git a/PROJECTS/docker-security-audit/learn/codebase-guide.md b/PROJECTS/docker-security-audit/learn/codebase-guide.md new file mode 100644 index 00000000..9adfa85d --- /dev/null +++ b/PROJECTS/docker-security-audit/learn/codebase-guide.md @@ -0,0 +1,612 @@ +# Codebase Guide + +A walkthrough of the code structure and what each package does.

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. + +## Further Reading + +- [CIS Docker Benchmark v1.6.0](https://www.cisecurity.org/benchmark/docker) +- [Docker
