Findings for Blue
Write AD findings for blue team from $LAB_AD — structured rows, observed vs inferred, ATT&CK and Event ID links, no attack cookbooks.
Visual · t25_findings_for_blue
Findings for blue = defender-ready report rows. $LAB_AD sourced. Original Cyberlium.
Blue needs a finding they can ticket — not a stranger-domain attack montage with Mimikatz screenshots.
AD finding structure for blue: title, affected object ($LAB_AD domain/OU/account), misconfiguration class (ACL path, weak SPN, tier violation, missing Guard), observed evidence (log excerpt, graph edge name, config read — from authorized lab), ATT&CK technique ID, recommended detection (Event ID + alert name from Module 8), severity in lab context. Observed vs inferred labels mandatory. Cyberlium findings from $LAB_AD and authorized purple exercises — NOT findings from unauthorized prod AD tests, NOT attach full Kerberoast/DCSync command transcripts against strangers, NOT publish live cred dumps as severity proof. chmod 600 under $HOME/cyberlium-lab/reports. Feeds capstone evidence pack.
1. Finding row template
Summary, asset, misconfig class, evidence, ATT&CK, detection, severity, owner recommendation.
Blue-readable: ticket title suggestion in summary line.

Primary tools to practice this lesson: python3, grep. Reference sites: Findings for blue (https://www.cisa.gov/resources-tools/resources/active-directory-security-best-practices); MITRE ATT&CK (https://attack.mitre.org/); Microsoft security operations (https://learn.microsoft.com/en-us/security/operations/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Evidence hygiene
Redact paths; lab domain only; graph edge names OK — stranger hostnames refused.
Log lines synthetic or $LAB_AD — label source.
3. Scope integrity
$LAB_AD RoE block in every report pack.
Refused: dramatized DA takeover video from unauthorized AD.
4. What you ship: blue finding template
Finding row fields + observed/inferred rule + sample row from lab.
5. What you record before the next lesson
Blue finding template path.
6. Wrong vs right: stranger-domain attacks vs lab AD literacy
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
- Wrong: Finding includes DCSync output from employer DC as evidence.
- Right: Blue finding template from $LAB_AD work. Next: Remediation Recs.
Mission: blue finding template
1) List finding row fields. 2) Write observed vs inferred rule. 3) Draft one finding from paths lab. 4) Link Event ID detection.
