Incident Response Skill

Purpose

This skill establishes comprehensive procedures for detecting, analyzing, containing, eradicating, and recovering from security incidents affecting the CIA platform. It implements systematic incident management aligned with NIST SP 800-61r2, ISO 27035, and Hack23 ISMS Incident Response Plan with measurable response times and transparent communication.

When to Use This Skill

Apply this skill when:

  • ✅ Detecting security alerts or suspicious activity
  • ✅ Responding to security breaches or data exposure
  • ✅ Managing vulnerability exploitation incidents
  • ✅ Coordinating response to service disruptions
  • ✅ Handling supply chain security incidents
  • ✅ Meeting GDPR 72-hour breach notification requirements
  • ✅ Conducting post-incident analysis and lessons learned
  • ✅ Updating incident response playbooks

Do NOT use for:

  • ❌ Routine maintenance or planned downtime
  • ❌ Non-security operational issues
  • ❌ Performance degradation without security implications

- **Date Detected:** 2024-01-15 09:30 UTC
- **Date Resolved:** 2024-01-16 14:00 UTC
- **Severity:** S2 (High)
- **Duration:** 28.5 hours

## Incident Details
- **Type:** Unauthorized access attempt
- **Attack Vector:** Exposed API endpoint with weak authentication
- **Affected Systems:** Production API server (EC2 instance i-0123456789abcdef)
- **Data Impact:** No data exfiltration confirmed
- **Business Impact:** €8K estimated revenue loss (service degradation)

## Timeline

## Root Cause Analysis
**What Happened:**
New API endpoint deployed without authentication middleware. Exposed endpoint allowed unauthenticated access to internal admin functions.

**Why It Happened:**
- Code review process did not catch missing @PreAuthorize annotation
- Integration tests did not include security test cases
- Deployment pipeline lacked security gate (CodeQL did not run)

**Contributing Factors:**
- Tight deadline pressure led to shortened review
- Developer unfamiliar with Spring Security patterns
- Security requirements not explicitly documented in user story

## What Went Well
- ✅ Detection within 15 minutes (GuardDuty alert)
- ✅ Incident validation within 15 minutes
- ✅ Containment within 1 hour (met RTO)
- ✅ Clear communication with CEO throughout
- ✅ No data loss or exfiltration
- ✅ Root cause identified quickly

## What Went Wrong
- ❌ Vulnerability introduced during deployment
- ❌ Code review did not catch security issue
- ❌ Security tests inadequate
- ❌ Deployment pipeline lacked security gate
