3. Incident Response Process

3.1 Preparation

Preventative Measures: - Security awareness training - Vulnerability management - Baseline security configurations - System hardening procedures - Regular security assessments

Preparation Activities: - Maintain and test incident response procedures - Conduct tabletop exercises - Establish communication channels - Prepare necessary tools and resources

3.2 Identification

Detection Sources: - Security monitoring systems - Intrusion detection/prevention systems - Antivirus/antimalware alerts - User reports - Third-party notifications

Initial Assessment: - Verify if event is a security incident - Determine initial scope and impact - Document initial findings - Assign initial severity level

Severity Levels: | Level | Description | Examples | Response Time | |——-|————-|———-|—————| | Critical | Severe impact on critical systems or data | Data breach, ransomware | Immediate | | High | Significant impact on important systems | Targeted attack, system compromise | < 1 hour | | Medium | Limited impact, isolated systems | Malware on non-critical system | < 4 hours | | Low | Minimal impact, easily contained | Policy violation, suspicious activity | < 24 hours |

3.3 Containment

Short-term Containment: - Isolate affected systems - Block malicious IP addresses - Disable compromised accounts - Preserve evidence

Long-term Containment: - Apply temporary fixes - Enhance monitoring - Implement additional security controls - Prepare for eradication

3.4 Eradication

Eradication Activities: - Identify and remove root cause - Scan for additional compromises - Patch vulnerabilities - Rebuild systems if necessary - Validate security posture

3.5 Recovery

Recovery Activities: - Restore systems from clean backups - Gradually restore operations - Implement additional security measures - Monitor for abnormal activity - Verify system functionality

Recovery Prioritization: | Priority | System Type | Recovery Time Objective | |———-|————-|————————-| | 1 | Mission-critical systems | < 4 hours | | 2 | Business-critical systems | < 24 hours | | 3 | Important systems | < 72 hours | | 4 | Non-critical systems | < 1 week |

3.6 Lessons Learned

Post-Incident Review: - Conduct post-incident meeting - Document incident timeline - Identify what worked well - Identify areas for improvement - Update incident response plan

4. Communication Plan

4.1 Internal Communication

Communication Protocols: - Initial notification procedures - Status update frequency - Escalation procedures - Communication methods

4.2 External Communication

Stakeholder Notification: - Customers - Partners - Regulators - Law enforcement

Media Communication: - Designated spokesperson - Approved messaging - Media response procedures

6. Incident Response Documentation

6.1 Incident Tracking

All incidents will be documented in the incident tracking system, including: - Incident ID - Date and time of detection - Nature of the incident - Systems/data affected - Actions taken - Resolution status - Lessons learned

6.2 Documentation Templates

  • Initial incident report
  • Incident log
  • Evidence chain of custody
  • Post-incident report

7. Testing and Maintenance

7.1 Plan Testing

  • Annual tabletop exercises
  • Biannual technical drills
  • Post-incident reviews

7.2 Plan Maintenance
