عن هذا المسار

Defenders work backwards from evidence. This path puts you in the responder's seat: given logs, a captured network trace, and a host that was pulled offline after suspicious activity, you reconstruct what the attacker did and recover what they tried to hide. You practise the day-to-day skills of a Security Operations Centre — log triage, timeline building, and spotting persistence.

لمن هذا المسار

Analysts and aspiring defenders who want hands-on incident-response practice: reading logs, following an intrusion through the artefacts it leaves, and understanding attacker techniques from the defender's side.

المتطلّبات المسبقة

Comfort on a Linux shell (cat, grep, less) and reading common log formats. A little base64/XOR decoding helps. The Pre-Security path is a good warm-up.

ما الذي ستتمكّن من فعله

  • Triage authentication and web-server logs to separate noise from the real intrusion
  • Build an incident timeline from disparate evidence
  • Detect and read attacker persistence (systemd units, cron, scripts)
  • Recover staged or deleted artefacts from a live host
  • Reverse simple real-world obfuscation to read what was exfiltrated
