Unit 737: Incident Response and Disaster Recovery in Cybersecurity

1. Introduction to Incident Response and Disaster Recovery

• Definition and scope of Incident Response (IR) and Disaster Recovery (DR)
• Importance in cybersecurity and organizational resilience
• Differences between Incident Response and Disaster Recovery
• Significance in maintaining business continuity

2. Incident Response Process

• Overview of the incident response lifecycle
• Steps involved:
  • Preparation: policies, tools, training
  • Identification: detection and analysis techniques
  • Containment: short-term and long-term containment strategies
  • Eradication: removing cause and affected elements
  • Recovery: restoring systems and verifying integrity
  • Lessons Learned: documentation and improvement
• Best practices and frameworks (e.g., NIST, SANS)
• Role of communication and documentation throughout the process

3. Incident Classification and Prioritization

• Criteria for classification: type, severity, impact
• Prioritization based on risk and business impact
• Use of incident response metrics and KPIs
• Tools and methodologies for incident classification

4. Threat Intelligence and Incident Detection

• Role of threat intelligence in proactive defense
• Sources of threat intelligence (internal, external, open-source)
• Security tools for monitoring and alerting (IDS/IPS, SIEM, EDR)
• Techniques for timely incident detection
• Importance of early detection in minimizing damage

5. Data Breach Response

• Specific considerations for data breach incidents
• Containment strategies for breaches
• Notification requirements and timelines (legal and regulatory)
• Forensic analysis methods for breach investigation
• Legal implications and managing stakeholder communications

6. Disaster Recovery Planning

• Understanding disaster recovery and its objectives
• Risk assessment and identification of threats
• Business impact analysis (BIA) to prioritize recovery efforts
• Development of recovery strategies (RTO, RPO concepts)
• Plan development: documentation and resource allocation
• Testing and maintenance of the disaster recovery plan

7. Business Continuity Management

• Relationship between incident response, disaster recovery, and business continuity
• Identifying critical business functions
• Continuity strategies to maintain operations during disruptions
• Establishing alternate work arrangements and communication plans
• Continuous improvement of business continuity plans

8. Incident Response Simulation and Tabletop Exercises

• Purpose and benefits of simulations and tabletop exercises
• Designing and conducting effective exercises
• Roles, scenarios, and expected outcomes
• Evaluating team coordination and response effectiveness
• Identifying gaps and areas for improvement

9. Incident Response Team Roles and Responsibilities

• Overview of typical incident response team structure
• Roles and duties:
  • Incident Commander
  • Forensic Analysts
  • Communication Coordinators
  • Legal Advisors
  • Other support roles
• Importance of coordination and clear responsibilities

10. Data Backup and Recovery

• Importance of regular data backups for disaster recovery
• Backup strategies: full, incremental, differential
• Technologies and tools for backup
• Best practices to ensure data integrity and availability

11. Incident Response Tools and Technologies

• Overview of key tools:
  • Security Information and Event Management (SIEM) systems
  • Incident response platforms
  • Forensic analysis tools
• How tools assist in detection, containment, and recovery

12. Legal and Regulatory Considerations in Incident Response

• Overview of data breach notification laws
• Industry-specific regulations and compliance standards (e.g., GDPR, HIPAA)
• Legal challenges in incident response
• Documentation and evidence preservation
• Ensuring compliance throughout the incident lifecycle
