# Security Incident Response Plan ## Executive Summary This document establishes the Security Incident Response Plan for the Review Bot Automator project. It provides procedures for detecting, responding to, and recovering from security incidents, ensuring consistent and effective handling of security events. **Purpose**: Define processes, roles, and procedures for managing security incidents from detection through resolution and lessons learned. **Scope**: Covers all security incidents affecting the Review Bot Automator project, including: * Code vulnerabilities and exploits * Dependency compromises * Data breaches and leaks * System compromises * Supply chain attacks **Last Updated**: 2025-11-03 **Next Review**: Semi-annually or after major incidents --- ## Incident Classification ### Severity Levels #### CRITICAL (P0) **Response Time**: Immediate (< 1 hour) **Resolution Time**: 24-72 hours #### Examples * Remote code execution vulnerability actively exploited * Complete system compromise * Mass data breach * Supply chain attack affecting production users * Credential theft with evidence of unauthorized access **Escalation**: Immediate notification to security team, maintainers, and stakeholders --- #### HIGH (P1) **Response Time**: < 4 hours **Resolution Time**: 1 week #### Examples: (Critical Severity) * Path traversal vulnerability discovered * Secrets leaked in public repository * Dependency with critical CVE * Unauthorized access to CI/CD pipeline * Code injection vulnerability **Escalation**: Notify security team and maintainers within 1 hour --- #### MEDIUM (P2) **Response Time**: < 1 business day **Resolution Time**: 2 weeks #### Examples: (High Severity) * Information disclosure vulnerabilities * Dependency with high-severity CVE * Security misconfiguration * Denial of service vulnerability * Authentication bypass **Escalation**: Notify security team and schedule fix --- #### LOW (P3) **Response Time**: < 1 week **Resolution Time**: 1 month #### Examples: (Medium Severity) * Minor information disclosure * Low-severity CVEs * Security best practice violations * Non-critical misconfigurations **Escalation**: Track in issue tracker, schedule for next release --- ## Incident Response Phases ### Phase 1: Detection and Reporting #### Detection Methods 1. **Automated Detection** * **CodeQL Analysis**: Scans for security vulnerabilities in code (`.github/workflows/security.yml`) * **Trivy SBOM Scanning**: Detects vulnerabilities in dependencies * **TruffleHog**: Scans for accidentally committed secrets * **Scorecard**: Evaluates security best practices * **ClusterFuzzLite**: Detects crashes, memory issues, and edge cases * **pip-audit**: Identifies known vulnerabilities in Python dependencies * **Bandit**: Static analysis for Python security issues 2. **Manual Detection** * Code review findings * Security researcher reports * User reports via GitHub issues * Internal security audits 3. **External Notifications** * GitHub Security Advisories * CVE alerts from dependencies * Security mailing lists * Disclosure from security researchers #### Reporting Channels ##### Private Disclosure (Preferred) * GitHub Security tab → "Report a vulnerability" * Creates private security advisory * Allows for coordinated disclosure **Email**: * Use for sensitive disclosures * Include detailed reproduction steps * Expect acknowledgment within 48 hours **GitHub Issues**: For non-critical issues * Use "security" label * Do NOT include sensitive details * Public visibility #### Contacts * **Security Team**: * **Project Maintainers**: Listed in CODEOWNERS file * **Emergency**: (24/7 monitoring) --- ### Phase 2: Triage and Assessment #### Initial Assessment (< 1 hour for CRITICAL) ##### Step 1: Acknowledge Receipt * Confirm receipt to reporter within documented SLA * Assign incident ID (format: `SEC-YYYY-NNNN`) * Create private tracking issue (GitHub Security Advisory) #### Step 2: Validate Vulnerability * Attempt to reproduce the issue * Verify exploitability * Assess actual vs theoretical impact * Document reproduction steps ### Step 3: Assign Severity Use CVSS v3.1 scoring (): * **CRITICAL**: CVSS 9.0-10.0 * **HIGH**: CVSS 7.0-8.9 * **MEDIUM**: CVSS 4.0-6.9 * **LOW**: CVSS 0.1-3.9 #### Step 4: Determine Impact Scope * Affected versions * Number of users potentially impacted * Data at risk * Attack complexity * Prerequisites for exploitation #### Assessment Template ```markdown ## Incident: SEC-2025-NNNN **Severity**: [CRITICAL/HIGH/MEDIUM/LOW] **CVSS Score**: [0.0-10.0] **Reported By**: [Name/Anonymous] **Reported Date**: YYYY-MM-DD HH:MM UTC **Acknowledged**: YYYY-MM-DD HH:MM UTC ### Description [Brief description] ### Affected Components * Component: [name] * Versions: [x.y.z - a.b.c] * File(s): [file paths] ### Impact * Confidentiality: [NONE/LOW/HIGH] * Integrity: [NONE/LOW/HIGH] * Availability: [NONE/LOW/HIGH] ### Exploit Complexity * Prerequisites: [list] * Attack Vector: [NETWORK/ADJACENT/LOCAL] * User Interaction: [NONE/REQUIRED] ### Reproduction Steps 1. [Step 1] 2. [Step 2] ... ### Evidence [Screenshots, logs, PoC code] ``` --- ### Phase 3: Containment #### Immediate Actions (CRITICAL/HIGH) ##### Step 1: Stop the Bleeding * If exploit is active, consider emergency actions: * Disable affected features via configuration * Roll back to safe version * Block malicious traffic (if applicable) * Revoke compromised credentials #### Step 2: Prevent Spread * Identify all affected systems * Isolate compromised components * Prevent further exploitation * Monitor for additional indicators of compromise #### Step 3: Preserve Evidence * Capture system state * Save logs and artifacts * Document timeline * DO NOT destroy evidence during containment #### Containment Strategies by Threat Type ##### Code Vulnerability 1. Create hotfix branch 2. Develop and test fix 3. Prepare advisory and patch 4. Coordinate disclosure timeline #### Dependency Compromise 1. Pin to last known-good version 2. Assess impact of vulnerable component 3. Search for alternative dependencies 4. Test with pinned version #### Secret Leakage 1. **IMMEDIATELY** revoke exposed credentials 2. Rotate all potentially affected secrets 3. Audit access logs for unauthorized use 4. Remove secrets from git history (`git filter-branch`) 5. Force push cleaned history (coordination required) #### CI/CD Compromise 1. Disable affected workflows 2. Review recent workflow runs 3. Audit workflow permissions 4. Rotate all GitHub Actions secrets 5. Review recent commits for malicious changes --- ### Phase 4: Eradication #### Root Cause Analysis ##### Questions to Answer 1. What was the vulnerability? 2. How long has it existed? 3. What allowed it to exist? 4. Were there any previous indicators? 5. Could it have been prevented? #### Analysis Methods * Code review of vulnerable component * Git history analysis (`git log --all -- `) * Dependency tree analysis * Timeline reconstruction * Impact assessment #### Fix Development ##### Development Process 1. Create hotfix branch from affected version 2. Develop minimal fix (avoid scope creep) 3. Add regression tests 4. Add security test cases 5. Test fix thoroughly 6. Code review by at least 2 maintainers 7. Security team approval #### Fix Validation * [ ] Vulnerability no longer exploitable * [ ] No new regressions introduced * [ ] Tests pass (unit, integration, security) * [ ] Fuzzing passes (if applicable) * [ ] Code review approved * [ ] Security team approval #### Patch Strategy * Backport to all supported versions (currently 0.1.x) * Create separate fix branches per major version * Test each backport independently * Prepare release notes (without sensitive details) --- ### Phase 5: Recovery #### Deployment ##### CRITICAL/HIGH Severity 1. Prepare emergency release 2. Notify users via: * GitHub Security Advisory * Release notes * Email to known users (if applicable) * Security mailing lists 3. Publish patched versions to PyPI 4. Update documentation 5. Monitor for issues post-deployment #### MEDIUM/LOW Severity 1. Include fix in next regular release 2. Document in changelog 3. Mention in release notes 4. No emergency notification required #### Post-Deployment Monitoring **Monitoring Period**: 7 days for CRITICAL, 3 days for HIGH #### What to Monitor * Error rates * Unexpected behavior reports * Performance metrics * Security scan results * User feedback #### Success Criteria * No new exploitation attempts detected * No regression issues reported * Security scans clear * User adoption of patched version increasing --- ### Phase 6: Post-Incident Review #### Lessons Learned Meeting **Timing**: Within 7 days of incident resolution #### Participants * Security team * Incident responders * Relevant maintainers * (Optional) Security researcher who reported #### Agenda 1. Incident timeline review 2. What went well? 3. What could be improved? 4. Root cause analysis 5. Preventive measures 6.
