This curriculum spans the design and operationalization of an ISO 27001-aligned incident response function, comparable in scope to a multi-phase internal capability program that integrates with audit, legal, and security operations across the enterprise.
Module 1: Aligning Incident Response with ISO 27001:2022 Control Objectives
- Determine which ISO 27001:2022 Annex A controls (e.g., A.5.24, A.8.16) require integration with incident response procedures and map them to response workflows.
- Define the scope of incident response within the Statement of Applicability (SoA) to reflect organizational risk appetite and control exclusions.
- Establish formal linkages between incident response outcomes and management review inputs as required by Clause 9.3.
- Implement documented decision criteria for triggering incident response based on control failure detection (e.g., failed access control logs).
- Integrate incident classification levels with the organization’s risk assessment methodology to ensure consistent prioritization.
- Configure monitoring mechanisms for control effectiveness post-incident, such as retesting access controls after a breach.
- Assign responsibility for incident response activities in the SoA using RACI matrices aligned with control ownership.
- Update asset inventories (A.8.1.1) dynamically during incident investigations to maintain accuracy in impact assessment.
Module 2: Designing an Incident Response Team with Clear Accountability
- Appoint a formally designated Incident Response Manager with documented authority to escalate and allocate resources during crises.
- Define cross-functional team roles (e.g., forensic analyst, legal liaison, PR officer) and embed them in organizational charts and job descriptions.
- Establish escalation paths for incidents involving third-party vendors, specifying contractual obligations for notification and cooperation.
- Implement a duty roster to ensure 24/7 coverage, including backup personnel and succession planning for key roles.
- Conduct role-specific training for legal and compliance staff on handling evidence to meet admissibility standards.
- Document decision logs during incidents to support post-event accountability and audit trails.
- Negotiate pre-approved authority levels for team members to take actions such as isolating systems or suspending user accounts.
- Integrate incident response roles with business continuity and crisis management teams to avoid duplication and gaps.
Module 3: Developing an Incident Classification and Prioritization Framework
- Define classification criteria based on data sensitivity, system criticality, and regulatory exposure (e.g., PII vs. public data).
- Implement a scoring model (e.g., CVSS adapted for business impact) to assign severity levels to incidents consistently.
- Set thresholds for reporting incidents to senior management and external regulators based on classification outcomes.
- Map classification levels to predefined response playbooks to ensure appropriate resource allocation.
- Revise classification criteria annually or after major incidents to reflect changes in threat landscape or business operations.
- Train help desk and SOC analysts to apply classification rules during initial triage without over-classifying.
- Document exceptions where low-severity incidents require elevated handling due to reputational or legal risk.
- Integrate classification outcomes into the organization’s risk register for ongoing monitoring.
Module 4: Implementing Detection and Reporting Mechanisms
- Configure SIEM correlation rules to detect anomalies that align with known attack patterns in the organization’s environment.
- Establish mandatory reporting procedures for employees, including anonymous channels, with clear examples of reportable events.
- Integrate endpoint detection and response (EDR) tools with the incident management platform for automated alert ingestion.
- Define SLAs for initial assessment of reported incidents (e.g., 15 minutes for critical, 4 hours for low).
- Implement automated enrichment of alerts with asset criticality and user role data to accelerate triage.
- Validate detection coverage across cloud workloads, on-prem systems, and third-party services to identify blind spots.
- Conduct quarterly false positive analysis to refine detection rules and reduce analyst fatigue.
- Document and test procedures for receiving alerts from external sources such as CERTs or law enforcement.
Module 5: Executing Containment, Eradication, and Recovery Procedures
- Select containment strategies (e.g., network segmentation, account disabling) based on incident type and potential collateral impact.
- Pre-approve forensic imaging procedures and tools to preserve volatile data without violating privacy policies.
- Define criteria for when to isolate systems versus allowing controlled monitoring for threat intelligence gathering.
- Coordinate with IT operations to schedule eradication and recovery during maintenance windows to minimize business disruption.
- Validate clean backups before initiating recovery, including integrity checks and malware scanning.
- Implement change control procedures for post-incident system reconfiguration to prevent configuration drift.
- Document all actions taken during containment and eradication for audit and legal defensibility.
- Conduct post-recovery vulnerability scans to confirm that exploited weaknesses have been remediated.
Module 6: Conducting Post-Incident Reviews and Root Cause Analysis
- Facilitate blameless post-mortems within 72 hours of incident resolution to capture accurate recollections.
- Use structured root cause analysis methods (e.g., 5 Whys, Fishbone) to distinguish between technical failures and process gaps.
- Assign ownership and deadlines for corrective actions identified during the review, tracking them in a centralized system.
- Compare actual response performance against predefined KPIs such as mean time to detect (MTTD) and contain (MTTC).
- Update incident response playbooks based on lessons learned, including new detection signatures or communication templates.
- Share anonymized incident summaries with relevant departments to improve organizational awareness.
- Integrate findings into the organization’s internal audit plan to verify implementation of corrective actions.
- Archive incident records in accordance with data retention policies and legal requirements.
Module 7: Integrating Legal, Regulatory, and Compliance Requirements
- Determine notification timelines for data breaches under GDPR, HIPAA, or other applicable regulations based on jurisdiction and data type.
- Establish a legal review checkpoint before external communications or regulatory filings are released.
- Maintain a registry of all regulatory reporting obligations and assign responsibility for each.
- Coordinate with outside counsel to manage privileged communications during investigations.
- Document decisions to not report incidents, including justification based on risk assessment and legal advice.
- Implement data subject request procedures that align with breach notification timelines.
- Preserve chain of custody for digital evidence in accordance with jurisdictional legal standards.
- Conduct annual reviews of incident response procedures against changes in regulatory frameworks.
Module 8: Managing Communication and Stakeholder Engagement
- Develop pre-approved messaging templates for internal staff, customers, regulators, and media based on incident severity.
- Define a single point of contact for external communications to ensure message consistency.
- Implement secure communication channels (e.g., encrypted email, dedicated chat) for incident response team coordination.
- Conduct briefings for executive leadership at defined intervals during prolonged incidents.
- Train customer support teams on how to respond to inquiries without disclosing sensitive details.
- Document all external communications for regulatory and audit purposes.
- Establish criteria for when to engage public relations or crisis communication specialists.
- Validate communication plans through tabletop exercises involving legal, PR, and executive stakeholders.
Module 9: Testing, Maintaining, and Auditing the Incident Response Capability
- Schedule annual full-scale incident response exercises involving technical, legal, and executive teams.
- Design scenario-based tests that reflect realistic threats to the organization’s critical assets.
- Use red team engagements to evaluate detection and response capabilities under real-world conditions.
- Track and trend incident response metrics over time to identify performance degradation or improvement.
- Conduct unannounced drills to assess readiness and team availability.
