Security checklist

Area	What to know	Common trap
Access	IAM, service accounts, least privilege, identity boundaries	granting Owner because a narrow role is missing from memory
Network security	firewall rules, private access, segmentation, perimeter controls	treating identity controls as network controls
Data protection	encryption, key management, DLP, storage controls	assuming encryption alone solves access and governance
Detection and response	logging, monitoring, threat signals, incident workflow	collecting logs without knowing what action they support
Compliance	policy, audit evidence, retention, governance mapping	claiming compliance from a tool name alone

Must-know distinctions

IAM role versus service account: roles grant permissions; service accounts provide workload identity.
Encryption at rest versus key management: encryption may be automatic, but key control and rotation can be separate requirements.
Organization policy versus detective control: policy prevents or constrains; detection finds and alerts.
Public access prevention versus firewall rule: storage exposure and network traffic are different risk paths.
Incident containment versus eradication: first limit impact, then remove root cause and restore safely.

Common traps

Solving every problem with broader access.
Ignoring auditability and evidence in compliance scenarios.
Treating logs as useful without alerting, ownership, or response.
Confusing network reachability with authorization.

Practice strategy

For each question, identify the asset, identity, network boundary, data sensitivity, and evidence requirement. The best answer usually reduces risk while preserving a workable operations path.
