Incident Response — Your Hack Action Plan
When (not if) your organization gets hacked, a proper incident response plan is the difference between a minor incident and a catastrophic breach.
NIST Incident Response Framework
Phase 1: Preparation
- ☐ Incident Response Team defined
- ☐ Communication plan ready
- ☐ Backup systems tested monthly
- ☐ EDR/SIEM deployed and configured
- ☐ Incident playbooks created
Phase 2: Detection & Analysis
- ☐ Identify the attack vector
- ☐ Determine scope of compromise
- ☐ Collect and preserve evidence
- ☐ Classify severity (P1/P2/P3/P4)
Phase 3: Containment
- ☐ Isolate affected systems from network
- ☐ Block attacker's IP/C2 domains
- ☐ Preserve system images for forensics
- ☐ Reset compromised credentials
Phase 4: Eradication
- ☐ Remove malware and backdoors
- ☐ Patch exploited vulnerabilities
- ☐ Rebuild compromised systems
- ☐ Verify clean state
Phase 5: Recovery
- ☐ Restore from clean backups
- ☐ Monitor closely for re-compromise
- ☐ Gradually restore services
Phase 6: Lessons Learned
- ☐ Post-incident report
- ☐ Root cause analysis
- ☐ Update security controls
- ☐ Improve detection capabilities
Average Breach Costs
- 💰 Global average: $4.45 million per breach
- 💰 India average: ₹17.9 crore per breach
- 💰 Organizations with IR plans save 58% in breach costs
