CYBERSECURITY ANALYST ROADMAP · STAGE 03 OF 04
Security monitoring and investigation
Interpret alerts and logs, preserve context, and investigate suspicious activity using authorized data.
Build a repeatable investigation narrative that separates observed facts from hypotheses.
CORE SKILLS
Key concepts in security monitoring and investigation
Logs and telemetry
Understand what endpoint, identity, and network events can establish and what they cannot prove on their own.
Topics include
- Event sources and timestamps
- Normalization and retention
- Coverage gaps and data quality
Alert triage
Assess alert context, affected assets, and corroborating evidence before escalating an event.
Topics include
- Severity and confidence
- False-positive review
- Escalation criteria
Detection concepts
Describe a defensive detection as observable behavior and validate it against benign and suspicious cases.
Topics include
- Indicators versus behavior
- Detection logic and tuning
- Testing for missed and noisy alerts
Threat intelligence context
Use credible threat information to enrich an investigation without treating an indicator match as proof.
Topics include
- Source reliability and freshness
- Indicators and their limitations
- Mapping activity to defensive knowledge bases
APPLY WHAT YOU LEARN
Practical project
Analyze a public, benign sample log set or synthetic events and write a timeline that labels facts, assumptions, and follow-up checks.
CHECK YOUR UNDERSTANDING
You are ready to move on when
- Can support conclusions with recorded evidence.
- Can communicate uncertainty and avoid claiming attribution without evidence.
