# Responding To Security Incidents

## Overview

Guide the full NIST SP 800-61 incident response lifecycle: detection, containment, eradication, recovery, and post-incident analysis. Classify incidents by type (ransomware, data breach, DDoS, credential compromise, insider threat) and severity, then coordinate evidence preservation, threat containment, and root-cause investigation.

## Prerequisites

- System and application logs accessible in `${CLAUDE_SKILL_DIR}/logs/` (auth logs, web server logs, database access logs)
- Network traffic captures (PCAP) or SIEM alert exports available
- Incident response team contact information and escalation paths documented
- Backup systems operational and recovery procedures tested
- Write permissions for incident documentation in `${CLAUDE_SKILL_DIR}/incidents/`
- Forensic tools available: Volatility (memory), Autopsy/FTK Imager (disk), tcpdump/Wireshark (network)
