Lab — Segments
Pack microseg overview, east-west matrix, and policy groups — network/microseg file from $ZT_LAB.
Visual · t40_microseg_lab
Lab: microseg pack. $ZT_LAB only. Original Cyberlium.
Opening
Microseg pack merges tier diagram, east-west flows, and policy groups into LAB-ZT-001/network/microseg-pack.md.
Merge M5 lessons into one microseg pack with combined architecture diagram showing segments, flows, and policy group legend. No lateral movement validation, unauthorized scanning, or employer network exports. Next: Quiz — Microsegmentation.
1. Lab contract: microseg pack
microseg-pack.md: overview + east-west matrix + policy groups + combined diagram.
LAB SAMPLE label and link to identity/device packs.
Command guide
Try these commands — Lab contract: microseg pack
═══ 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

Primary tools to practice this lesson: grep, curl. Reference sites: NIST SP 800-207 (https://csrc.nist.gov/publications/detail/sp/800-207/final); CISA ZTMM Networks (https://www.cisa.gov/zero-trust-maturity-model). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Cross-check
Grep exploit, nmap internal, mimikatz, real subnet CIDRs from employer — remove.
Confirm fictional example.zt.local addressing only.
3. Lock
chmod 600. Quiz next — ZTNA Named.
Microseg pack feeds ZTNA boundary design in M6.
4. What you ship: microseg pack
Merged microseg artifacts in LAB-ZT-001/network/. $ZT_LAB. NO attack tools. chmod 600.
5. What you record before the next lesson
Date. Microseg pack path. $ZT_LAB named. File t40-m05-l04-microseg-lab.txt chmod 600.
6. Wrong vs right: bypass cookbooks vs YOUR ZT design
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Add internal pentest script appendix. Paste employer datacenter diagram.
Right
Write microseg pack for $ZT_LAB. Next: Quiz — Microsegmentation.
Mission: microseg pack
1) Merge M5 sections. 2) Combined segment diagram. 3) Ethics cross-refs. 4) chmod 600.
