This curriculum spans the full lifecycle of an ISO 27001 ISMS implementation, equivalent in depth to a multi-workshop advisory engagement, covering scoping, risk treatment, control deployment, audit preparation, and ongoing governance across diverse organizational units and third-party relationships.

Module 1: Establishing the ISMS Framework

  • Selecting the scope of the Information Security Management System (ISMS) based on business units, geographic locations, and regulatory boundaries.
  • Defining top management roles and responsibilities for ISMS oversight, including appointment of an ISMS manager with documented authority.
  • Conducting a formal gap analysis between current security practices and ISO 27001:2022 requirements.
  • Developing a documented ISMS policy aligned with organizational risk appetite and strategic objectives.
  • Establishing criteria for risk assessment methodology, including asset valuation, threat likelihood, and impact scales.
  • Integrating ISMS planning with existing enterprise risk management (ERM) frameworks.
  • Setting measurable objectives for information security with defined metrics and timelines.
  • Creating a documented statement of applicability (SoA) that justifies inclusion or exclusion of Annex A controls.

Module 2: Risk Assessment and Treatment

  • Identifying information assets by business function, ownership, and criticality to operations.
  • Selecting and applying a risk assessment methodology (qualitative vs. quantitative) based on organizational maturity and data availability.
  • Conducting threat and vulnerability analysis using industry benchmarks and internal incident data.
  • Assigning risk owners for each identified high-risk scenario and documenting their accountability.
  • Developing risk treatment plans with specific actions: mitigate, accept, transfer, or avoid.
  • Validating risk treatment effectiveness through control testing and residual risk reviews.
  • Establishing thresholds for acceptable risk based on business impact and regulatory requirements.
  • Documenting risk acceptance decisions with sign-off from authorized personnel and review schedules.

Module 3: Annex A Control Implementation

  • Mapping selected Annex A controls to identified risks and business processes.
  • Configuring access control policies (A.9) based on role-based access (RBAC) and least privilege principles.
  • Implementing encryption standards (A.10) for data at rest and in transit, aligned with regulatory mandates.
  • Establishing secure development practices (A.14) for in-house software and vendor-supplied systems.
  • Deploying network security controls (A.13) including segmentation, firewall rules, and intrusion detection.
  • Configuring logging and monitoring controls (A.16) to ensure event traceability and incident response readiness.
  • Implementing supplier security requirements (A.15) through contractual clauses and audit rights.
  • Enforcing physical security measures (A.11) for data centers and offices, including access logs and surveillance.

Module 4: Policy Development and Documentation

  • Drafting an information security policy suite covering acceptable use, data handling, and remote work.
  • Aligning security policies with legal, statutory, and contractual obligations across jurisdictions.
  • Establishing a document control process for versioning, review cycles, and access permissions.
  • Integrating policy exceptions into the risk register with documented justification and review dates.
  • Mapping policy requirements to specific roles and responsibilities in job descriptions.
  • Creating policy awareness mechanisms such as digital acknowledgments and training triggers.
  • Ensuring policy language is enforceable and consistent with disciplinary procedures.
  • Conducting periodic policy reviews triggered by incidents, audits, or regulatory changes.

Module 5: Internal Audit and Compliance Monitoring

  • Designing an internal audit schedule based on risk profile, control criticality, and business changes.
  • Selecting qualified internal auditors with independence from the functions being audited.
  • Developing audit checklists aligned with ISO 27001 clauses and the organization’s SoA.
  • Conducting sample testing of control implementation and effectiveness across departments.
  • Reporting audit findings with root cause analysis and assigning corrective action owners.
  • Tracking non-conformities to closure using a formal corrective action management system.
  • Integrating compliance monitoring with continuous controls monitoring tools (e.g., SIEM, GRC platforms).
  • Preparing for external audits by validating evidence availability and audit trail completeness.

Module 6: Management Review and Continuous Improvement

  • Scheduling formal management review meetings with defined agenda items per ISO 27001 clause 9.3.
  • Presenting performance metrics such as incident rates, control effectiveness, and audit results.
  • Evaluating changes in internal and external issues affecting the ISMS (e.g., mergers, new regulations).
  • Reviewing resource adequacy for maintaining and improving the ISMS.
  • Updating ISMS objectives based on performance data and strategic shifts.
  • Documenting management decisions and action items with assigned owners and deadlines.
  • Assessing the effectiveness of previous corrective actions and improvement initiatives.
  • Ensuring review outputs are traceable to subsequent changes in policy, scope, or risk treatment.

Module 7: Incident Management and Business Continuity

  • Defining incident classification criteria based on impact, data type, and regulatory reporting thresholds.
  • Establishing an incident response team with defined roles, escalation paths, and communication protocols.
  • Integrating the ISMS incident response plan with existing IT service management (ITSM) processes.
  • Conducting post-incident reviews to identify control gaps and update response procedures.
  • Testing incident response plans through tabletop exercises and simulated breaches.
  • Aligning ISMS continuity requirements with organizational business continuity management (BCM) plans.
  • Ensuring backup procedures (A.12.3) are tested regularly and meet recovery time objectives (RTO).
  • Documenting and reporting security incidents to regulators where required by law (e.g., GDPR, HIPAA).

Module 8: Third-Party and Supply Chain Risk

  • Classifying suppliers based on data access, criticality, and security risk exposure.
  • Conducting security assessments of high-risk vendors using standardized questionnaires or audits.
  • Embedding security requirements in procurement contracts, including right-to-audit clauses.
  • Monitoring supplier compliance through periodic reviews and performance scorecards.
  • Managing cloud service provider risks in alignment with CSA CCM and ISO 27017.
  • Establishing processes for onboarding and offboarding suppliers with security checks.
  • Integrating supplier incidents into the organization’s risk and incident management processes.
  • Ensuring subcontractor oversight by requiring prime vendors to flow down security obligations.

Module 9: Certification and External Audit Preparation

  • Selecting an accredited certification body based on industry reputation and audit scope expertise.
  • Conducting a pre-certification readiness assessment to validate documentation and control operation.
  • Preparing evidence files for all ISMS controls, including logs, policies, and training records.
  • Coordinating site access and stakeholder availability for the external audit team.
  • Responding to certification audit findings with corrective action plans and evidence of resolution.
  • Negotiating the scope of certification to reflect actual operational boundaries and exclude test environments.
  • Managing surveillance audit schedules and maintaining evidence continuity between audits.
  • Updating the ISMS following certification to reflect audit feedback and organizational changes.

Module 10: Sustaining and Scaling the ISMS

  • Integrating ISMS updates into change management processes for M&A, divestitures, or new technologies.
  • Scaling the ISMS to new business units by conducting localized risk assessments and scoping.
  • Automating control monitoring and evidence collection using GRC or integrated security platforms.
  • Establishing key performance indicators (KPIs) for ISMS maturity and executive reporting.
  • Conducting periodic benchmarking against industry standards and peer organizations.
  • Managing staff turnover by embedding security roles into HR onboarding and offboarding workflows.
  • Updating training programs based on control gaps identified in audits or incidents.
  • Aligning ISMS evolution with emerging threats, technological changes, and updated regulatory landscapes.
