Description

This curriculum spans the design, execution, and governance of an ISO 27001-aligned incident response function, comparable in scope to a multi-phase internal capability buildout involving cross-functional teams, legal integration, technical tooling, and audit coordination across complex enterprise environments.

Module 1: Establishing the Foundation for Incident Response Governance

Define the scope of incident response activities across business units, including subsidiaries and third-party providers, to align with ISO 27001:2022 control 5.24.
Select and document criteria for classifying incidents based on business impact, data sensitivity, and regulatory exposure.
Assign formal roles within the Computer Security Incident Response Team (CSIRT), including escalation paths and decision rights during crisis events.
Integrate incident response planning with existing risk assessment outcomes from the ISMS to prioritize response capabilities.
Determine thresholds for declaring a formal incident versus operational disruption, minimizing false positives while ensuring timely activation.
Establish governance oversight mechanisms, such as quarterly CSIRT performance reviews by the Information Security Steering Committee.
Develop a process for maintaining response plan currency amid organizational changes, including M&A activity or cloud migration.
Align incident response objectives with business continuity and disaster recovery timelines to avoid conflicting recovery priorities.

Module 2: Legal and Regulatory Alignment in Response Planning

Map mandatory breach notification timelines (e.g., GDPR 72 hours, HIPAA 60 days) into incident response escalation workflows.
Engage legal counsel to pre-approve communication templates for regulators, minimizing delays during active incidents.
Define data preservation protocols that meet chain-of-custody requirements for potential litigation or regulatory audits.
Implement jurisdiction-specific handling rules for cross-border data transfers during forensic collection.
Document decision criteria for involving law enforcement, including thresholds for financial loss or national security implications.
Integrate regulatory change monitoring into the ISMS review cycle to update response playbooks accordingly.
Establish a legal hold process to suspend routine data deletion schedules upon incident detection.
Coordinate with external counsel on jurisdictional liability exposure when third-party vendors are involved in an incident.

Module 3: Designing the Incident Response Team Structure and Escalation Framework

Define primary and backup personnel for critical CSIRT roles, including technical lead, communications officer, and business liaison.
Implement a 24/7 escalation tree with verified contact methods (e.g., secure messaging, dial-in bridges) and failover procedures.
Specify decision authority levels for actions such as system isolation, external disclosure, or ransom payment evaluation.
Conduct role-based access provisioning for incident response tools (e.g., SIEM, EDR) with audit logging enabled.
Establish cross-functional liaison roles with IT operations, legal, PR, and executive management for coordinated response.
Develop a process for onboarding temporary or external experts (e.g., forensics consultants) with pre-vetted access agreements.
Define criteria for activating crisis management teams during incidents affecting critical business functions.
Implement periodic revalidation of team member availability and contact information to ensure reliability.

Module 4: Developing and Maintaining Incident Response Playbooks

Construct playbooks for high-risk scenarios (e.g., ransomware, insider threat, cloud account compromise) with step-by-step actions.
Embed decision trees for containment strategies, including network segmentation, credential rotation, or service shutdown.
Integrate playbook steps with existing monitoring tools to trigger automated alerts and evidence collection.
Define playbook ownership and review cycles, requiring updates after each major incident or control change.
Include communication templates for internal stakeholders, customers, and regulators within each playbook.
Specify evidence collection procedures that preserve forensic integrity without disrupting business operations.
Map playbook actions to ISO 27001 controls (e.g., 8.16, 5.7) to demonstrate compliance during audits.
Version-control playbooks and maintain a change log accessible to authorized personnel only.

Module 5: Integration with Detection and Monitoring Capabilities

Configure SIEM correlation rules to trigger predefined incident response workflows based on threat intelligence feeds.
Define thresholds for alert prioritization to reduce noise and ensure critical events reach response personnel.
Implement automated enrichment of alerts with asset criticality, user role, and data classification metadata.
Establish feedback loops from responders to SOC analysts to refine detection logic after incident resolution.
Integrate endpoint detection and response (EDR) tools to enable remote isolation and memory capture from affected systems.
Validate monitoring coverage across hybrid environments, including SaaS applications and remote workforce endpoints.
Define retention periods for logs required for forensic reconstruction, aligned with legal and operational needs.
Conduct quarterly validation of detection-to-response handoff timing to identify process bottlenecks.

Module 6: Communication and Stakeholder Management Protocols

Develop role-specific communication templates for executives, board members, customers, and regulators.
Assign a designated spokesperson to control external messaging and prevent conflicting statements.
Implement a secure internal communication channel (e.g., encrypted collaboration platform) for incident coordination.
Define approval workflows for public statements, requiring joint sign-off from legal, PR, and security leadership.
Establish a process for notifying affected individuals in compliance with data protection laws.
Conduct pre-incident media training for key spokespeople to ensure consistent messaging under pressure.
Log all external communications for audit and regulatory review purposes.
Coordinate with third-party vendors on joint communication plans when shared systems are involved.

Module 7: Evidence Handling and Forensic Readiness

Define forensic data acquisition procedures for cloud environments, including API-based log extraction and snapshot preservation.
Establish secure storage locations for forensic images with access restricted to authorized personnel.
Document chain-of-custody forms for physical and digital evidence, including timestamps and handler signatures.
Pre-negotiate contracts with external forensic labs to reduce mobilization time during incidents.
Validate forensic tool compatibility with organizational systems (e.g., virtualization platforms, container runtimes).
Implement write-blockers and hashing procedures to maintain evidence integrity during analysis.
Define criteria for when to engage law enforcement with forensic findings versus internal resolution.
Conduct periodic validation of forensic tool licenses and software update status.

Module 8: Testing, Exercising, and Performance Measurement

Design tabletop exercises focused on high-impact scenarios, with injects simulating real-time decision pressure.
Conduct live fire drills in isolated environments to validate technical containment and eradication steps.
Measure mean time to detect (MTTD) and mean time to respond (MTTR) across incident types for performance tracking.
Document gaps identified during exercises and assign remediation owners with deadlines.
Include third-party vendors in joint testing scenarios when they are part of critical response workflows.
Use red team findings to update response playbooks and detection rules.
Report exercise outcomes and improvement metrics to the Information Security Steering Committee quarterly.
Implement post-exercise debriefs with structured feedback collection from all participants.

Module 9: Continuous Improvement and Audit Readiness

Integrate incident response performance data into the ISMS management review process.
Conduct root cause analysis for all declared incidents to identify systemic control deficiencies.
Update risk treatment plans based on incident trends and emerging threat intelligence.
Maintain an incident repository with anonymized details for training and trend analysis.
Prepare audit packages demonstrating compliance with ISO 27001 controls 5.24, 8.16, and 5.7.
Implement corrective action tracking for findings from internal audits and external assessments.
Align response plan updates with organizational changes such as technology refresh or business expansion.
Conduct annual benchmarking against industry frameworks (e.g., NIST SP 800-61) to identify capability gaps.
