    ## Core Capabilities
    
    ### 1. Security Scanner
    
    Scan source code for security vulnerabilities including hardcoded secrets, SQL injection, XSS, command injection, and path traversal.
    
    ```bash
    # Scan project for security issues
    python scripts/security_scanner.py /path/to/project
    
    # Filter by severity
    python scripts/security_scanner.py /path/to/project --severity high
    
    # JSON output for CI/CD
    python scripts/security_scanner.py /path/to/project --json --output report.json
    ```
    
    **Detects:**
    - Hardcoded secrets (API keys, passwords, AWS credentials, GitHub tokens, private keys)
    - SQL injection patterns (string concatenation, f-strings, template literals)
    - XSS vulnerabilities (innerHTML assignment, unsafe DOM manipulation, React unsafe patterns)
    - Command injection (shell=True, exec, eval with user input)
    - Path traversal (file operations with user input)
    
    ### 2. Vulnerability Assessor
    
    Scan dependencies for known CVEs across npm, Python, and Go ecosystems.
    
    ```bash
    # Assess project dependencies
    python scripts/vulnerability_assessor.py /path/to/project
    
    # Critical/high only
    python scripts/vulnerability_assessor.py /path/to/project --severity high
    
    # Export vulnerability report
    python scripts/vulnerability_assessor.py /path/to/project --json --output vulns.json
    ```
    
    **Scans:**
    - `package.json` and `package-lock.json` (npm)
    - `requirements.txt` and `pyproject.toml` (Python)
    - `go.mod` (Go)
    
    **Output:**
    - CVE IDs with CVSS scores
    - Affected package versions
    - Fixed versions for remediation
    - Overall risk score (0-100)
    
    ### 3. Compliance Checker
    
    Verify security compliance against SOC 2, PCI-DSS, HIPAA, and GDPR frameworks.
    
    ```bash
    # Check all frameworks
    python scripts/compliance_checker.py /path/to/project
    
    # Specific framework
    python scripts/compliance_checker.py /path/to/project --framework soc2
    python scripts/compliance_checker.py /path/to/project --framework pci-dss
    python scripts/compliance_checker.py /path/to/project --framework hipaa
    python scripts/compliance_checker.py /path/to/project --framework gdpr
    
    # Export compliance report
    python scripts/compliance_checker.py /path/to/project --json --output compliance.json
    ```
    
    **Verifies:**
    - Access control implementation
    - Encryption at rest and in transit
    - Audit logging
    - Authentication strength (MFA, password hashing)
    - Security documentation
    - CI/CD security controls

    ## Workflows
    
    ### Workflow 1: Security Audit
    
    Complete security assessment of a codebase.
    
    ```bash
    # Step 1: Scan for code vulnerabilities
    python scripts/security_scanner.py . --severity medium
    
    # Step 2: Check dependency vulnerabilities
    python scripts/vulnerability_assessor.py . --severity high
    
    # Step 3: Verify compliance controls
    python scripts/compliance_checker.py . --framework all
    
    # Step 4: Generate combined report
    python scripts/security_scanner.py . --json --output security.json
    python scripts/vulnerability_assessor.py . --json --output vulns.json
    python scripts/compliance_checker.py . --json --output compliance.json
    ```
    
    ### Workflow 2: CI/CD Security Gate
    
    Integrate security checks into deployment pipeline.
    
    ```yaml
    # .github/workflows/security.yml
    name: Security Scan
    
    on:
      pull_request:
        branches: [main, develop]
    
    jobs:
      security-scan:
        runs-on: ubuntu-latest
        steps:
          - uses: actions/checkout@v4
    
          - name: Set up Python
            uses: actions/setup-python@v5
            with:
              python-version: '3.11'
    
          - name: Security Scanner
            run: python scripts/security_scanner.py . --severity high
    
          - name: Vulnerability Assessment
            run: python scripts/vulnerability_assessor.py . --severity critical
    
          - name: Compliance Check
            run: python scripts/compliance_checker.py . --framework soc2
    ```
    
    ### Workflow 3: CVE Triage
    
    Respond to a new CVE affecting your application.
    
    ```
    1. ASSESS (0-2 hours)
       - Identify affected systems using vulnerability_assessor.py
       - Check if CVE is being actively exploited
       - Determine CVSS environmental score for your context
    
    2. PRIORITIZE
       - Critical (CVSS 9.0+, internet-facing): 24 hours
       - High (CVSS 7.0-8.9): 7 days
       - Medium (CVSS 4.0-6.9): 30 days
       - Low (CVSS < 4.0): 90 days
    
    3. REMEDIATE
       - Update affected dependency to fixed version
       - Run security_scanner.py to verify fix
       - Test for regressions
       - Deploy with enhanced monitoring
    
    4. VERIFY
       - Re-run vulnerability_assessor.py
       - Confirm CVE no longer reported
       - Document remediation actions
    ```
    
    ### Workflow 4: Incident Response
    
    Security incident handling procedure.
    
    ```
    PHASE 1: DETECT & IDENTIFY (0-15 min)
    - Alert received and acknowledged
    - Initial severity assessment (SEV-1 to SEV-4)
    - Incident commander assigned
    - Communication channel established
    
    PHASE 2: CONTAIN (15-60 min)
    - Affected systems identified
    - Network isolation if needed
    - Credentials rotated if compromised
    - Preserve evidence (logs, memory dumps)
    
    PHASE 3: ERADICATE (1-4 hours)
    - Root cause identified
    - Malware/backdoors removed
    - Vulnerabilities patched (run security_scanner.py)
    - Systems hardened
    
    PHASE 4: RECOVER (4-24 hours)
    - Systems restored from clean backup
    - Services brought back online
    - Enhanced monitoring enabled
    - User access restored
    
    PHASE 5: POST-INCIDENT (24-72 hours)
    - Incident timeline documented
    - Root cause analysis complete
    - Lessons learned documented
    - Preventive measures implemented
    - Stakeholder report delivered
    ```
