OPSEC Basics
OPSEC named literacy covers threat modeling, compartmentation, metadata awareness, and need-to-know handoff — draft OPSEC rows on YOUR $DW_LAB fictional scenarios before identity compartment lesson.
Visual · t39_opsec_named
OPSEC named literacy. $DW_LAB only. Original Cyberlium.
Anonymity tools fail without OPSEC — literacy teaches threat model vocabulary so $DW_LAB notes document what you protect and from whom, not criminal target profiling.
OPSEC — Operations Security — asks who the adversary is, what you protect, what you accept as risk, and how metadata leaks deanonymize even encrypted content. On Cyberlium you practice on fictional scenario rows in YOUR $DW_LAB — lab persona alert stubs, placeholder metadata fields — never real target profiling, doxxing, or victim PII. Cyberlium maps OPSEC named row on YOUR $DW_LAB — threat model summary, compartmentation note, metadata awareness, need-to-know handoff boundary. Next: Identity Compartment.
1. OPSEC components (named)
Threat model: identify adversary, assets to protect, and accepted risks on YOUR fictional scenario. Compartmentation: separate identities, devices, and accounts — lab vocabulary for privacy engineering. Metadata: timing, location, billing, device fingerprints — not just message content. Need-to-know: share minimum for defender handoff through legal channels only.
On $DW_LAB, write OPSEC named row — adversary, asset, metadata field example, handoff boundary.
Command guide
Try these commands — OPSEC components (named)
═══ 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, python3. Reference sites: EFF SSD (https://ssd.eff.org/); Tor Project (https://www.torproject.org/); NIST privacy (https://www.nist.gov/privacy-framework). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Why OPSEC precedes hardened OS literacy
Tails and Whonix address technical isolation — OPSEC addresses behavioral and organizational leaks. Defenders triaging dark-web alerts need metadata vocabulary to scope corroboration without over-collection.
Students draft lab OPSEC rows on notes — production OPSEC follows org policy and authorized monitoring programs.
3. Lab boundary
Forbidden: real target profiling, doxxing exercises, criminal persona research blending with employer credentials. Allowed: OPSEC named card — fictional scenario rows with $DW_LAB FAKE/LAB labels.
Ship: OPSEC named row for YOUR lab notes. Next: Identity Compartment.
4. What you ship: OPSEC named row for $DW_LAB
Threat model, compartmentation, metadata, need-to-know. $DW_LAB named. chmod 600.
5. What you record before the next lesson
Date. OPSEC named row. $DW_LAB named. File t39-m03-l01-opsec-named.txt chmod 600.
6. Wrong vs right: criminal markets vs YOUR OPSEC lab
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
- Wrong: Profile real individuals for OPSEC lab exercise. Skip adversary definition because 'it's obvious.'
- Right: Write OPSEC named row for fictional scenario on YOUR $DW_LAB. Next: Identity Compartment.
Mission: draft OPSEC vocabulary on YOUR lab notes
1) Name adversary and asset in fictional scenario. 2) Write one metadata leak example. 3) Add need-to-know handoff boundary. 4) chmod 600.
