Use these visual guides to connect the key ideas before answering the questions.

Connect the roles in Security Logs and Event SourcesKeep event source, timestamp context, identity context, and log collection as separate roles.
Connect the roles in Security Logs and Event SourcesA topic-specific model connects four distinct roles used to reason about security logs and event sources.
Event serviceService creates records about system activity
Evidence timelineClock records time zone and event order
Sign-in contextIdentity connects account device and session
Journal recordsRecords move into protected central storage
Verify Retention and AccessConnect retention and access with its topic-specific inspection, expected outcome, and safety boundary.
Verify Retention and AccessA verification model for security logs and event sources connects the final decision to evidence, outcome, and a protected boundary.
Retention boundaryDecision limits log lifetime and reader access
Starting checkInspect retention boundary evidence
Expected resultVerify retention boundary result
