Microsoft Security SC-500 cheat sheet for key facts, traps, service mappings, and final review.
Use this cheat sheet for Microsoft Cloud and AI Security Engineer route (SC-500) after you know the basics but before you start a timed practice block. The goal is not to memorize a vendor catalog; the goal is to classify the scenario and reject attractive wrong answers quickly.
| Lane | Decision rule | Reject when |
|---|---|---|
| Identity and access | Protect users, apps, service principals, managed identities, privileged roles, and conditional access. | Solving every problem with network controls when identity is the first failure point. |
| Cloud posture and governance | Use policy, posture management, compliance evidence, regulatory controls, and remediation workflow. | Choosing a detective tool when the requirement is enforcement or prevention. |
| Data, network, and compute protection | Secure storage, databases, endpoints, virtual networks, containers, servers, and application paths. | Opening broad access for convenience or ignoring key and secret boundaries. |
| Defender, Sentinel, and incident response | Connect alerts, logs, automation, playbooks, and investigation flow to operational response. | Collecting telemetry without triage, ownership, or response action. |
| AI workload security | Protect model endpoints, prompt/data flows, agent tools, retrieval stores, and sensitive output. | Treating AI security as only content filtering instead of identity, data, network, and governance together. |
Use this when the stem mixes identity, policy, data protection, detection, or AI workload security.

| Trap | Better instinct |
|---|---|
| Confusing visibility with control | Match monitor, alert, enforce, remediate, and investigate to the exact requirement. |
| Bypassing least privilege | Scope identities, roles, secrets, and managed identities before adding broad permissions. |
| Missing data movement | Track where prompts, documents, embeddings, logs, and outputs are stored and accessed. |
| No response workflow | Security answers should leave evidence, ownership, and a way to contain or remediate. |
| If the stem says | Start with |
|---|---|
| least privilege, private access, compliance, or audit | identity scope, data boundary, policy enforcement, logging, and ownership |
| least operational effort | managed service, native integration, simple workflow, and fewer moving parts |
| high availability, recovery, or outage | failure domain, recovery objective, health check, rollback, and validation |
| performance, scale, or cost | bottleneck evidence, traffic pattern, sizing, caching, batching, and quotas |
| troubleshoot, diagnose, or investigate | symptom, recent change, logs, metrics, status, dependency, and smallest safe test |

Security questions usually want the minimum effective control with identity, data boundary, telemetry, and response ownership.
