Memory hook: Protect the mission before optimizing the toolset.
Must remember
- Identify business-critical assets, likely threats, impact and recovery objectives before selecting controls. Prioritize ransomware resilience around recoverable backups, privileged-access protection, patching and containment.
- Zero Trust means verify explicitly, use least privilege and assume breach. It is an architectural approach spanning identities, devices, networks, applications, data and workloads, not one purchased appliance.
- Microsoft Cybersecurity Reference Architectures map security capabilities; the Microsoft Cloud Security Benchmark supplies control guidance. Use them to identify gaps and ownership, not as evidence that deployment is already compliant.
- Cloud Adoption Framework guides adoption/governance; Well-Architected evaluates workload tradeoffs; landing zones establish scalable identity, network, subscription and policy foundations.
- BCDR must include isolated/immutable recovery where appropriate, clean identity recovery, keys, dependencies and restoration tests. Backups controlled by the same compromised administrator can be at risk.
- Secure AI adoption adds model/tool identities, data boundaries, prompt-injection defenses, evaluation and human oversight. DevSecOps brings threat modeling, code/dependency checks and release controls into the development lifecycle.
Choose under exam pressure
| Requirement | Choice and reason |
|---|---|
| Budget is limited after a ransomware assessment | Prioritize critical recovery paths and privileged-access risks with measurable impact. |
| New cloud subscriptions appear inconsistently | Governed landing zones with policy and delegated ownership. |
Traps
- A high security score is not proof the business can recover.
- Zero Trust does not mean denying every request or trusting only an internal network.
Active recall
1. What determines security priorities?
Business impact, threat likelihood, critical assets and control effectiveness.
2. Why isolate recovery access?
A compromise of production administration should not destroy every recovery option.
3. What does a reference architecture provide?
A structured capability/control model to adapt, not an automatically deployed solution.
4. Why test restore end to end?
Data recovery alone may fail if identity, keys, applications or dependencies are unavailable.
5. How does DevSecOps reduce risk?
By finding and addressing security issues throughout design, build, release and operation.
