Prepare Before the Incident Happens

Organizations should not design their incident-response process while an attack is already underway.

Effective incident response requires documented responsibilities, communication channels, decision authorities, technical procedures, evidence-handling practices, recovery plans, and lessons-learned processes.

The Modern Incident Response Lifecycle — IBACTP® recommends organizing incident readiness across the six core operating phases:

01

1. GOVERN & PREPARE

Establish readiness, policies, communication channels, and authority structures before incidents occur.

Preparation activities include:

  • Incident response policy and team charter definition
  • Severity matrix and incident classification standards
  • External legal, regulatory, and PR escalation workflows
  • System and asset inventory maintenance
  • Centralized logging configuration and forensic telemetry
  • Tabletop simulation exercises and backup validation

2. DETECT & ANALYZE

Rapidly identify, validate, and triage anomalous security alerts and indicator signals.

Core analytical questions include:

  • Initial compromise vector and timeline identification
  • Compromised systems, accounts, and privileged credentials
  • Data exposure, exfiltration, or tampering assessment
  • Ongoing malicious actor persistence mechanisms
  • Business operational impact and financial exposure
  • Forensic evidence preservation and chain-of-custody

3. CONTAIN

Limit immediate blast radius and stop lateral movement while preserving critical forensics.

Containment strategies include:

  • Endpoint isolation and affected subnet micro-segmentation
  • C2 infrastructure blocking and DNS firewall filtering
  • Compromised account disablement and session revocation
  • Firewall rule adjustments and perimeter hardening
  • Temporary service degradation versus business continuity
  • Forensic memory dumping and disk imaging before shutdown

4. ERADICATE

Completely eliminate malware, unauthorized footholds, and root causes from the environment.

Eradication measures include:

  • Root-cause vulnerability patching and remediation
  • Malware, web shell, and persistence script removal
  • Rogue account termination and enterprise credential reset
  • Rebuilding compromised servers from trusted baseline images
  • Correction of vulnerable security misconfigurations
  • Secondary validation scanning and threat hunting

5. RECOVER

Safely restore systems and business operations with enhanced monitoring and validation.

Recovery workflows include:

  • System restoration from clean, offline immutable backups
  • Staged reconnect with heightened telemetry and logging
  • Integrity verification of restored files and databases
  • User and customer business-service resumption
  • Stakeholder and regulatory notification management
  • Short-term threat monitoring against re-infection

6. LEARN & IMPROVE

Conduct comprehensive post-incident analysis to strengthen preventive security controls.

Continuous improvement includes:

  • Blameless post-mortem and root-cause analysis sessions
  • Incident timeline reconstruction and control gap discovery
  • Detection signature and alerting rule enhancements
  • Incident response playbook updates and revisions
  • Security awareness training updates based on real attacks
  • Executive risk reporting and strategic posture investment
