Phase 1: Preparation

Identify incident response team members and roles
Document escalation procedures and contact information
Establish relationships with legal counsel and forensics firms
Create communication templates for various scenarios
Implement credential monitoring for early breach detection
Conduct regular tabletop exercises

Phase 2: Detection & Analysis

1
Confirm the Incident

Determine if an actual breach occurred vs. a false positive. Document initial findings.

2
Assess Scope

What systems are affected? What data was exposed? How many records?

3
Preserve Evidence

Capture logs, memory dumps, and system states before any remediation.

Phase 3: Containment & Eradication

Isolate affected systems to prevent spread
Reset credentials for compromised accounts
Block attacker access (IPs, accounts, malware)
Patch vulnerabilities that enabled the breach
Remove any persistence mechanisms

Phase 4: Notification

Legal Requirements
Most jurisdictions require breach notification within specific timeframes (e.g., GDPR requires 72 hours). Consult legal counsel immediately to understand your obligations.
Internal Notifications
  • Executive leadership
  • Legal department
  • HR (if employee data affected)
  • Communications/PR
External Notifications
  • Affected customers
  • Regulatory authorities
  • Law enforcement (if applicable)
  • Cyber insurance carrier

Phase 5: Recovery & Lessons Learned

Restore systems from clean backups
Verify eradication was successful
Monitor for signs of continued compromise
Conduct post-incident review
Update security controls based on findings
Implement additional monitoring (like credential monitoring)
