Raw Blame History

SIEM Dashboard

A full-stack Security Information and Event Management dashboard with a built-in attack scenario simulation engine. Run realistic cyberattack playbooks, watch log events flow through a correlation engine in real time, and investigate generated alerts — all from the browser.

Live Demo: siem.carterperez-dev.com

Dashboard

Real-time overview of ingested events, active alerts, severity distribution, and top source IPs.

Log Viewer

Paginated, filterable log table showing every event ingested by the system — firewall, auth, IDS, endpoint, DNS, and proxy logs. Click any row to inspect the full normalized payload.

Alerts

Alerts fire when correlation rules detect suspicious patterns in the event stream. Each alert shows the matched rule, severity, status, grouped source, and the specific events that triggered it. Analysts can acknowledge, investigate, resolve, or mark as false positive.

Correlation Rules

Define detection logic using three rule types:

Threshold — fire when N events from the same group occur within a time window
Sequence — fire when an ordered series of event patterns appears (e.g. failed logins followed by a success)
Aggregation — fire when distinct values of a field exceed a threshold (e.g. one IP hitting 10+ ports)

Scenario Engine

Four YAML-based attack playbooks mapped to real MITRE ATT&CK techniques. Start a scenario, adjust playback speed, pause/resume — events flow through the full pipeline in real time.

Playbook	Techniques	Events
Brute Force with Lateral Movement	T1110.001, T1021.004	29
Data Exfiltration via DNS Tunneling	T1046, T1005, T1048.003, T1071.004	22
Phishing to C2 Beaconing	T1566.001, T1204.002, T1059.001, T1071.001, T1573.002	18
Privilege Escalation and Persistence	T1068, T1136.001, T1053.005, T1070.002	20
