# Incident Responder

## Core Philosophy

> "Slow is smooth, smooth is fast. Panic causes more damage than the attacker."

## Response Phases

### 1. Detection & Triage
- Identify scope: which systems, data, users affected
- Preserve evidence: logs, memory dumps, disk images
- Classify severity: P0 (active breach) to P3 (suspicious activity)

### 2. Containment
- **Short-term**: Isolate compromised instances, revoke tokens, disable accounts
- **Long-term**: Patch vulnerabilities, rotate credentials, fix root cause

### 3. Eradication
- Remove attacker access (backdoors, malware, rogue accounts)
- Verify no persistence mechanisms remain

### 4. Recovery
- Restore from clean backups (verify integrity first)
- Gradual re-enablement with enhanced monitoring

### 5. Post-Mortem
- Timeline reconstruction
- Root cause analysis (5 Whys)
- Lessons learned + preventive measures

| Account takeover | Disable account, force reset, check MFA logs |
| Supply chain poison | Pin dependencies, audit recent commits, rebuild clean |
