security-assessment

Execute threat modeling, vulnerability scanning, and security control validation.

Triggers

• "run security review"
• "security assessment"
• "threat model [component]"
• "validate security controls"
• "security scan"
• "check vulnerabilities"

Purpose

This skill orchestrates comprehensive security assessment through:

• STRIDE threat modeling
• Vulnerability pattern detection
• Security control validation
• Compliance verification
• Risk scoring and prioritization

Behavior

When triggered, this skill:

1. Determines scope:

   • Component-level, system-level, or full assessment
   • Identify assets and trust boundaries
   • Load existing threat model if available

2. Executes threat modeling:

   • Dispatch Security Architect for STRIDE analysis
   • Enumerate threats per component
   • Identify attack vectors

3. Runs vulnerability patterns:

   • Dispatch Security Auditor for pattern scanning
   • Check OWASP Top 10
   • Identify secrets exposure risks
   • Review dependency vulnerabilities

4. Validates controls:

   • Dispatch Security Gatekeeper
   • Map controls to threats
   • Verify implementation
   • Check coverage gaps

5. Assesses privacy:

   • Dispatch Privacy Officer (if PII involved)
   • Check data handling
   • Verify consent mechanisms

6. Generates report:

   • Risk-ranked findings
   • CVSS scores where applicable
   • Remediation guidance
   • Compliance status

STRIDE Threat Categories

Category	Description	Example
Spoofing	Impersonating something/someone	Fake user credentials
Tampering	Modifying data or code	SQL injection
Repudiation	Denying actions	Missing audit logs
Information Disclosure	Exposing information	Data leakage
