SOC › Module 3 › Lesson 4
Lab — SIEM
Pack pipeline, vendor, and query cards — SIEM literacy file from $SOC_LAB only.
Visual · t29_siem_lab
Lab: SIEM pack. $SOC_LAB only. Original Cyberlium.
Opening
SIEM pack merges pipeline to vendors to queries — paperwork before log sources module.
Lessons 3-1–3-3 named SIEM pipeline, Splunk/Elastic vocabulary, and query patterns. This lab merges three cards with optional jq output from YOUR $SOC_LAB auth sample. Optional: run jq count on failed auth in lab JSON — log command and UTC only; no stranger cluster. Next: Quiz — SIEM Literacy.
1. Lab contract: SIEM pack
Create $HOME/cyberlium-lab/t29-m03-l04-siem-lab.txt merging pipeline, vendor, and query sections with $SOC_LAB file paths and M1 ethics cross-reference.
Optional: paste redacted jq one-liner output — no real usernames from production exports.

═══ INSTALL ═══
Linux (Debian/Ubuntu):

brew install jq
Windows:

═══ LINUX / macOS ═══
Command — copy this
export SOC_LAB=${SOC_LAB:-$HOME/cyberlium-lab/t29-soc}
cat > "$SOC_LAB/notes/siem-query-cheatsheet.txt" <<'EOF'
YOUR lab jq queries (mimics SIEM thinking):
failed logons: jq -c 'select(.event_id==4625)' logs/auth.jsonl
by src_ip count: jq ... | sort | uniq -c
rare external IP: jq 'select(.src_ip|startswith("203."))' logs/auth.jsonl
SPL equivalent literacy: index=win EventCode=4625 | stats count by src_ip
never: run hydra/brute — detect pattern in YOUR seeded logs only
EOFCommand — copy this
jq -c 'select(.src_ip|startswith("203."))' "$SOC_LAB/logs/auth.jsonl"
grep -E 'failed logons|never' "$SOC_LAB/notes/siem-query-cheatsheet.txt"═══ WINDOWS ═══
Command — copy this
Get-Content $HOME/cyberlium-lab/t29-soc/logs/auth.jsonl | Select-String '"result":"failure"' Write-Output 'Filter YOUR auth.jsonl — detection literacy only, no brute-force tools'
Primary tools to practice this lesson: jq, grep. Reference sites: Elastic detection rules (https://www.elastic.co/guide/en/security/current/prebuilt-rules.html); MITRE T1110.001 (https://attack.mitre.org/techniques/T1110/001/); Sigma (https://github.com/SigmaHQ/sigma). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Cross-check ethics
Grep for Splunk token, Elastic API key, production index names — remove. Pack must label all queries as $SOC_LAB conceptual only.
Confirm time-bound language appears in every query example.
3. Lock the proof
chmod 600 on the pack. Quiz next — then Windows Auth Logs.
SIEM literacy feeds log-source lessons in M4.
4. What you ship: SIEM literacy pack for $SOC_LAB
Merged pipeline, vendor, query sections. $SOC_LAB named. NO stranger cluster. chmod 600.
5. What you record before the next lesson
Date. SIEM pack path. $SOC_LAB named. File t29-m03-l04-siem-lab.txt chmod 600.
6. Wrong vs right: stranger SIEM vs YOUR sample logs
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Include production Splunk index name in pack. Skip query intent section.
Right
Write YOUR SIEM literacy pack for $SOC_LAB. chmod 600. Next: Quiz — SIEM Literacy.
Mission: freeze YOUR SIEM literacy pack
1) Merge M3 literacy sections. 2) Confirm zero production tenant refs. 3) Link M1 ethics cross-ref. 4) chmod 600.
