Certifications get interviews. Practical skills get offers and promotions. This guide covers the blue-team skills that separate certified candidates from ones who can actually do the job.
Labs
- Build a small Active Directory lab with a domain controller and two clients
- Add attack simulation tools — Atomic Red Team, Caldera
- Run scenarios end-to-end: initial access, lateral movement, exfiltration
SIEM
Deploy Wazuh or Elastic in your lab, ingest Windows and Linux logs, and write your own dashboards. Understanding data flow beats memorising a vendor UI.
Threat Hunting
- Start with a hypothesis, not a tool
- Map every hunt to a MITRE ATT&CK technique
- Document assumptions and outcomes — hunts that find nothing are still evidence
Detection Engineering
- Write Sigma rules for common attack techniques
- Test rules against Atomic Red Team executions
- Measure noise, false positives, and mean time to detect
Blue Team Skills
- Incident response process and evidence handling
- Log analysis with grep, awk, and jq
- Basic scripting in Python or PowerShell
- Clear technical writing for post-incident reports
Frequently Asked Questions

Rotations, SOC internships, and CTFs like BTLO and CyberDefenders build muscle memory before your first real incident.
