PlannedCertified Information Security Manager
My condensed notes across all four CISM domains, following the ISACA review manual. One long page — use the table of contents or Ctrl+F.
I worked through the ISACA review manual domain by domain, condensed each into the rail notes below, and focused on the manager's lens — governance and risk over hands-on technique. These are personal study notes — verify anything exam-critical against official material. No exam content is reproduced here.
D1
Information security governance
17% · Aligning the security program with business strategy through governance structures and clear accountability.
Governance fundamentals
- Governance sets direction and oversight; management executes — the board owns risk appetite, the CISO runs the program.
- A security strategy must trace to business objectives — every control answers to a business driver, not the reverse.
- Governance value drivers — strategic alignment · risk management · value delivery · resource optimisation · performance measurement.
Roles and responsibilities
- Define accountability with a
RACI— board · steering committee · CISO · data owners · custodians · users. - The steering committee bridges business and security, prioritising investment against risk.
Frameworks and standards
- Map the program to a recognised framework —
ISO/IEC 27001·NIST CSF·COBIT 2019. - Governance, risk, and compliance (GRC) tooling keeps policy, risk, and control evidence in one place.
D2
Information security risk management
20% · Identifying, assessing, and treating information risk to a level the business accepts.
Risk concepts
- Inherent versus residual risk; risk appetite (how much you’ll pursue) versus tolerance (how much you’ll bear).
- Quantitative terms —
SLE(single loss expectancy) ·ARO(annual rate of occurrence) ·ALE = SLE × ARO.
Risk assessment
- Identify assets, threats, and vulnerabilities; assess likelihood and impact (qualitative or quantitative).
- Keep a living risk register — owner · score · treatment · review date — not a one-off spreadsheet.
Risk treatment
- Treat each risk explicitly — accept · avoid · transfer · mitigate — then monitor the residual.
- Spend on controls in proportion to asset value and exposure; a control must cost less than the risk it removes.
D3
Information security program
33% · Building and running the program — resources, controls, metrics, and assurance. The heaviest domain.
Program development
- A program turns strategy into a roadmap — people · process · technology — with a defined operating model.
- Align control objectives to the framework; baseline with standards such as
NIST SP 800-53and tailor to context.
Controls and operations
- Layer administrative, technical, and physical controls; prefer preventive, detect what you cannot prevent.
- Define an awareness program — phishing simulation · role-based training · measurable behaviour change.
Metrics and assurance
- Measure with
KPIs (performance) andKRIs (risk) that a business audience can read — not raw tool output. - Use independent assessment — internal audit ·
SOC 2· penetration tests — to validate the program, not just self-attest.
Third-party and supply-chain risk
- Assess vendors before onboarding and on a cycle; bake security terms, audit rights, and breach notification into contracts.
- Track the residual risk a provider carries on your behalf — outsourcing the work never outsources the accountability.
D4
Incident management
30% · Preparing for, detecting, responding to, and recovering from security incidents — and learning from them.
Incident response lifecycle
- Prepare → detect and analyse → contain → eradicate → recover → post-incident review (
NIST SP 800-61). - Define severity tiers and escalation up front; an incident is no time to invent the decision tree.
Preparation and detection
- Stand up an incident response plan, a trained team (CSIRT), and tested playbooks before you need them.
- Centralise detection —
SIEM· continuous monitoring · threat intelligence — and tune for signal over noise.
Business continuity and recovery
- Tie response to continuity metrics —
RTO(downtime) ·RPO(data loss) ·MTD(maximum tolerable downtime). - Test the plan with tabletop and failover exercises; an untested plan is an assumption, not a capability.
Communication and lessons learned
- Pre-agree who speaks to executives, customers, and regulators, and on what timeline — breach laws set hard clocks.
- Close every incident with a blameless review that feeds concrete fixes back into the program.
