Remediation Recs
Prioritized remediation and detection recommendations from $LAB_RT findings — actionable for blue and leadership.
Visual · t21_remediation_recs
Remediation = specific fix + owner + priority. From $LAB_RT gaps. Original Cyberlium.
Opening
Findings without fixes waste the exercise — give blue and IT specific next steps tied to techniques you emulated in lab.
Remediation recommendations translate purple gaps into prioritized actions: detection rule deploy, segmentation fix, credential tiering, persistence hardening, DLP tuning — each linked to ATT&CK row and $LAB_RT evidence. Use P1/P2/P3 or program severity scale; assign owner role (SOC, AD team, endpoint); include retest method on lab bench. Refuse vague 'be secure,' refuse recommending log clearing or evasion tools, refuse fixes that require attacking strangers to verify. Cyberlium teaches actionable closure on authorized exercises — stakeholders fund what is specific and measured.
1. Recommendation rows
Gap, root cause, recommended control, owner, priority, retest on $LAB_RT, target date placeholder.
Mix preventive (segmentation) and detective (Sigma idea) controls per gap.
Command guide
Try these commands — Recommendation rows
═══ LINUX / macOS (Terminal Practice) ═══
Check system state and user context
Command — copy this
id whoami uname -a
Inspect network sockets listening for connections
Command — copy this
ss -tuln 2>/dev/null || netstat -tuln
Audit active processes
Command — copy this
ps aux | grep -v "\[" | head -15
═══ WINDOWS (POWERSHELL) ═══ Query user identity and system information
Command — copy this
whoami /all Get-ComputerInfo | Select-Object CsName, OsName, OsVersion
Primary tools to practice this lesson: grep, curl. Reference sites: Remediation recommendations (https://www.cisa.gov/resources-tools/resources/red-team-exercises); Sigma detections (https://sigmahq.io/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Purple alignment
Each missed detection from Module 8 map becomes ≥1 recommendation — close the loop.
Celebrate detections that fired — reinforce good rules.
3. Refusal lines
No remediation that violates law (deploy spyware on strangers, steal creds to verify).
No anti-forensics as compensating control — ever.
4. What you ship: remediation table
≥5 prioritized rows linked to ATT&CK/evidence + retest method each.
5. What you record before the next lesson
Remediation table path.
6. Wrong vs right: stranger phishing vs authorized RT lab
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Recommend 'clear logs faster' as SOC improvement.
Right
Remediation table from purple gaps. Next: Report Lab.
Mission: remediation table
1) List gaps from detections map. 2) Write ≥5 recommendation rows. 3) Assign priority and owner role. 4) Define retest on $LAB_RT.
