Module 3: Designing IT Controls from Annex A
- Select appropriate access control mechanisms (RBAC, ABAC, or hybrid) based on application architecture and user population size.
- Implement encryption for data at rest and in transit, choosing key management approaches aligned with organizational capability.
- Configure logging levels on critical systems to capture authentication, privilege changes, and data access events.
- Define backup frequency and retention periods for databases based on recovery point objectives (RPO) and legal requirements.
- Establish secure configuration baselines for operating systems and network devices using CIS benchmarks or internal standards.
- Implement segregation of duties in privileged access systems to prevent single-user control over critical operations.
- Design monitoring rules for detecting unauthorized changes to firewall rules or DNS configurations.
- Integrate mobile device management (MDM) policies with A.9 controls for remote access and lost device scenarios.
Module 4: IT Governance and Management Structure
- Define reporting lines between CISO, CIO, and data protection officer to clarify decision authority on security incidents.
- Establish an IT security steering committee with representation from legal, compliance, and business units.
- Assign control ownership for each Annex A control to specific IT managers with operational responsibility.
- Develop escalation procedures for IT incidents that impact multiple systems or exceed defined severity thresholds.
- Implement formal change advisory boards (CAB) to evaluate security impact of infrastructure and application changes.
- Define service level agreements (SLAs) for incident response and patch deployment across IT teams.
- Introduce balanced scorecards to measure IT security performance against ISMS objectives.
- Conduct quarterly reviews of control effectiveness with IT leadership using audit findings and KPIs.
Module 5: Third-Party and Cloud Service Governance
- Classify cloud service providers by risk level based on data processed and integration depth with internal systems.
- Negotiate audit rights and access to compliance reports (e.g., SOC 2, ISO 27001) in contracts with critical vendors.
- Map shared responsibility models for IaaS, PaaS, and SaaS services to identify control ownership gaps.
- Implement continuous monitoring of third-party security posture using automated vendor risk assessment tools.
- Define acceptable encryption key management arrangements for data stored with cloud providers.
- Enforce secure API usage policies for integrations between internal applications and external platforms.
- Conduct due diligence on subcontractors used by primary vendors to ensure end-to-end control coverage.
- Establish exit strategies for cloud services, including data extraction and sanitization requirements.
Module 6: Incident Management and IT Response Operations
- Define criteria for classifying IT security incidents (e.g., malware, data exfiltration, DDoS) based on business impact.
- Integrate SIEM alerts with ticketing systems to ensure timely investigation of potential security events.
- Document forensic data collection procedures for compromised servers and endpoints in accordance with legal requirements.
- Establish communication protocols for notifying IT teams, management, and external parties during active incidents.
- Conduct post-incident reviews to identify control failures and update runbooks for recurring attack patterns.
- Test incident response plans annually using tabletop exercises focused on ransomware and supply chain attacks.
- Preserve logs and system images for a defined period to support regulatory investigations and litigation holds.
- Coordinate with external CSIRTs or MSSPs during large-scale incidents while maintaining internal oversight.
Module 7: Change Management and Secure System Development
- Enforce mandatory security reviews for all changes to production environments, including emergency changes.
- Integrate static and dynamic application security testing (SAST/DAST) into CI/CD pipelines for web applications.
- Define approval workflows for deployment of code changes based on system criticality and change impact.
- Implement segregation between development, testing, and production environments to prevent configuration drift.
- Require threat modeling for new applications that process personal or financial data.
- Enforce secure coding standards and conduct periodic code reviews for in-house developed software.
- Track open security defects in development projects and define remediation timelines based on severity.
- Validate that patches and updates are tested in staging environments before production rollout.
Module 8: Monitoring, Logging, and Technical Auditing
- Define log retention periods for different system types based on legal requirements and forensic needs.
- Centralize logs from firewalls, servers, and applications into a SIEM with write-once storage for integrity.
- Configure correlation rules to detect multi-stage attacks such as lateral movement or privilege escalation.
- Conduct quarterly technical audits of user access rights on critical systems to identify orphaned accounts.
- Validate that system clocks are synchronized across the environment using NTP for accurate log correlation.
- Implement automated alerts for failed login attempts, privilege changes, and unauthorized configuration modifications.
- Perform regular reviews of firewall rule sets to eliminate unused or overly permissive entries.
- Use vulnerability scanning tools to identify unpatched systems and enforce remediation timelines.
Module 9: Continuous Improvement and ISMS Reviews
- Analyze internal audit findings to prioritize improvements in high-risk IT control areas.
- Update the Statement of Applicability (SoA) based on changes in IT infrastructure or business operations.
- Conduct management review meetings with IT leadership to assess ISMS performance and resource needs.
- Track control effectiveness using metrics such as mean time to patch, incident recurrence rates, and false positive alerts.
- Revise risk assessments annually or after significant IT events like mergers or data center migrations.
- Implement corrective actions for nonconformities identified during external certification audits.
