Topic Synopsis
This element equips learners with the systematic approach to managing cyber security incidents from detection to recovery. It covers the establishment and operation of a Cyber Emergency Response Team (CERT), the integration of Disaster Recovery and Business Continuity Management to ensure organisational resilience, and the forensic investigative techniques required to analyse major security breaches. Mastery of these areas is essential for protecting digital assets and maintaining business operations during and after cyber attacks.
Key Concepts & Core Principles
- Confidentiality, Integrity, and Availability (CIA) Triad: The foundational model for security policies, ensuring data is accessible only to authorised users, remains unaltered, and is available when needed.
- Risk Management: The process of identifying, assessing, and prioritising risks, followed by coordinated application of resources to minimise, monitor, and control the impact of security incidents.
- Network Security Controls: Firewalls, intrusion detection/prevention systems (IDS/IPS), and VPNs that protect network perimeters and internal segments from unauthorised access and threats.
- Incident Response Lifecycle: Preparation, detection and analysis, containment/eradication/recovery, and post-incident activity – a structured approach to handling security breaches.
- Security Governance: Policies, procedures, and frameworks (e.g., ISO 27001) that define how an organisation manages and oversees its cyber security strategy and compliance.
Exam Tips & Revision Strategies
- Always align your incident response plan with a recognised framework such as NIST SP 800-61 or ISO/IEC 27035, and explicitly reference it in your assessment.
- When discussing investigations, use the correct forensic terminology: volatility order, chain of custody, write-blockers, and imaging to show deep understanding.
- In scenario-based questions, begin by prioritising containment to prevent further damage before moving to eradication and recovery.
- Integrate DR/BCM by explaining how Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) guide the restoration of services.
Common Misconceptions & Mistakes to Avoid
- Confusing Business Continuity Management with Disaster Recovery, treating them as identical rather than complementary disciplines.
- Overlooking the preparation phase of incident response, focusing only on reactive steps and neglecting proactive measures like playbook development and training.
- Failing to preserve evidence properly during an investigation, leading to contamination and inadmissible forensic findings.
- Assuming that a CERT operates only during an incident, without recognising the need for ongoing threat intelligence and simulation exercises.
- Neglecting communication protocols and stakeholder management, which can cause delays and misinformation during an incident.
Examiner Marking Points
- Award credit for clearly explaining the six-step incident response lifecycle (Preparation, Identification, Containment, Eradication, Recovery, Lessons Learned) and applying it to a given scenario.
- Credit demonstration of understanding CERT roles and responsibilities, including the designation of incident commander, technical analysts, and communication leads.
- Assess ability to distinguish between Disaster Recovery (IT-focused restoration) and Business Continuity Management (organisation-wide resilience) and describe how they support incident response.
- Look for evidence of planning a post-incident investigation, including preserving digital evidence, chain of custody, and using forensic tools.
- Reward practical application of documentation standards, such as incident logs, impact assessments, and post-incident reports.
