senior-security

Identify security threats across system components and data flows, score their risks, and prioritize mitigations. Run a quick scan for exposed credentials and route requests beyond threat modeling to the appropriate specialist skills.

Use when the user asks for STRIDE threat modeling, DREAD risk scoring, data-flow-diagram threat analysis, or a quick secret scan — or when a security request needs routing to the right specialist skill (pen-testing, incident response, cloud posture, red team, AI security, threat hunting, secure code review). This skill owns threat modeling; everything else routes to a sibling.

Senior Security Engineer — Threat Modeling + Security Router

This skill does exactly one job itself — STRIDE/DREAD threat modeling (plus a quick secret scan) — and routes every other security request to the specialist skill that owns that lane. Do not duplicate sibling content here; route instead.

Routing Table (read this first)

The user wants...Route toWhy that skill owns it
Vulnerability assessment, pen-test methodology, OWASP Top 10 testing../security-pen-testing/Ships vulnerability_scanner.py + dependency_auditor.py with exit-code contracts
Incident triage, SEV classification, forensics, containment../incident-response/SEV1–SEV4 taxonomy, NIST SP 800-61 phases, incident_triage.py
Production outage command (non-security incidents)../incident-commander/Severity classifier + timeline + postmortem tools
Security monitoring, CVE triage SLAs, compliance checks (SOC 2 etc.), security headers../senior-secops/security_scanner.py + compliance_checker.py, CVE SLA table
Hostile/adversarial code review../adversarial-reviewer/3-persona review with BLOCK/CONCERNS/CLEAN verdict
Secure code review as part of general review../code-reviewer/Language dispatch + regression fixtures
Cloud IAM escalation paths, S3 exposure, security groups../cloud-security/cloud_posture_check.py with per-check exit codes
Threat hunting, IOC sweeps, anomaly detection../threat-detection/z-score anomaly + IOC staleness tooling
Red-team engagement planning, ATT&CK kill chains../red-team/engagement_planner.py with authorization gate
LLM/AI attack surface (prompt injection, poisoning)../ai-security/ATLAS-mapped ai_threat_scanner.py

If the request spans lanes (e.g., "secure this new architecture"), do the threat model here first — its output (prioritized threats + mitigations) tells you which siblings to load next. Never bulk-load multiple security skills speculatively.

What This Skill Owns: STRIDE Threat Modeling

Workflow

  1. Scope: assets to protect, trust boundaries, data flows (external entities, processes, data stores, flows).
  2. Generate the threat model per component:
    python3 scripts/threat_modeler.py --component "User Authentication" --assets "credentials,sessions" --json --output threats.json
    
    Output: per-threat STRIDE category, DREAD score (Damage, Reproducibility, Exploitability, Affected users, Discoverability — each 1–10), and suggested mitigations. Repeat per DFD element; --interactive walks scoping questions; --list-threats shows the threat database.
  3. Consume the output: sort threats.json by DREAD score descending; everything ≥ 7 average needs a named mitigation owner before the design ships. Map each mitigation to the responsible sibling lane (e.g., IAM threats → cloud-security, injection threats → code-reviewer).
  4. Quick secret sweep while you have the codebase open:
    python3 scripts/secret_scanner.py /path/to/project --format json --severity high
    
    20+ patterns (AWS keys, GitHub tokens, private keys, generic credentials). Any critical/high finding blocks merge until rotated and moved to a secret manager.
  5. Verification gate: every DFD element has ≥ 1 STRIDE row considered, every threat with DREAD ≥ 7 has an owner + mitigation, and the secret scan exits with zero high/critical findings. Re-run both tools after mitigations land — that re-run is the done signal, not the document.

The architecture and crypto references are kept because no sibling ships them; for operating those controls (scanning, compliance, monitoring) still route to senior-secops.
