## 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
```
