DAY 4 · MODULE 3
Security Log Analysis
Read timestamps, users, source IPs and event types to reconstruct suspicious activity.
Understand the concept
Authentication logs
Web logs
Timestamps
Usernames
Source IP
Event sequences
Indicators
Why this matters
Logs provide evidence for understanding what occurred before, during and after a security event.
See what happens internally
Interactive visualization loads here.
Stage 2 Interactive Lab
Open Interactive LabOperate this concept in a larger realtime simulation and save your practical score.
Perform the activity
- Review the live incident timeline.
- Count failed logins.
- Identify the suspicious source.
- Build a short incident timeline from the prepared events.
Workshop safety: Activities involving scanning, web vulnerabilities or security testing must be performed only on the assigned training target or intentionally vulnerable lab.
Read and understand the working example
10:01 LOGIN_FAILED admin 10.0.0.20
10:02 LOGIN_FAILED admin 10.0.0.20
10:04 LOGIN_SUCCESS admin 10.0.0.20This example is shown for guided learning. Real host/network execution is reserved for the isolated cyber-range stage.
Prove your understanding
From the prepared events, identify the suspicious sequence and write a three-line incident summary.
