SOC Handoff
Sharing boundary literacy — need-to-know stub, partner NDA literacy, ISAC participation stub, public disclosure gate, intel retirement — named sharing rows on YOUR `$DW_LAB` fictional org.
Visual · t39_sharing_boundaries
Sharing boundaries = named distribution rows. $DW_LAB. Original Cyberlium.
Opening
Not every IOC belongs everywhere — name sharing boundary rows on YOUR lab org before leaking restricted intel publicly or sharing stranger org findings without authorization.
Sharing boundary literacy names: need-to-know distribution stub category, partner NDA literacy stub category, ISAC or ISAO participation stub category, public disclosure gate category, and intel retirement category. Analyst documents sharing boundaries card on `$DW_LAB` fictional org — five sharing rows linked to Module 8-1 TLP and Module 8-2 export control — without public posting of TLP-AMBER/RED intel, without sharing stranger org findings without authorization, without including crime how-tos in partner packs, without indefinite IOC retention without retirement review. Cyberlium teaches sharing vocabulary on YOUR notes. Refused: public restricted intel leak, unauthorized partner sharing, crime enablement in intel packs. Lab row: sharing boundaries card (five rows, disclosure gate, retirement stub, LAB label).
1. Named sharing rows
Need-to-know, partner NDA, ISAC stub, public disclosure gate, intel retirement — five anchors.
Each row cites `$DW_LAB` fictional org sharing policy — not live employer intel without authorization.

Sharing boundaries literacy:
TLP: label before share — WHITE/GREEN/AMBER/RED semantics
Need-to-know: dark-web IOCs may be AMBER — legal review for external share
Refused: paste live marketplace URLs in public Discord
Lab: mark all stubs TLP:WHITE + LAB-SAMPLE label
EOFCommand — copy this
grep -E 'TLP|Refused|LAB-SAMPLE' "$DW_TI/sharing-boundaries.txt"
python3 -c "print('TI sharing: TLP labels on YOUR $DW_LAB stubs only')"Primary tools to practice this lesson: grep, python3. Reference sites: FIRST sharing (https://www.first.org/global-sigs/trusted-introducer); TLP (https://www.first.org/tlp/); CISA (https://www.cisa.gov/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Disclosure discipline
Public disclosure gate requires review stub — not silent Twitter IOC dumps.
Intel retirement stub prevents stale IOC noise — link Module 8-2 triage.
3. Refused
No public TLP-RED/AMBER leaks; no unauthorized partner sharing; no crime how-tos in intel packs.
Sharing literacy supports trust — not intel carelessness.
4. What you ship: sharing boundaries card
Five sharing rows + disclosure gate + retirement stub + LAB label + NEVER public restricted intel line.
5. What you record before the next lesson

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
Post TLP-RED dark-web IOCs to public social channel as 'sharing boundaries awareness lab.'
Right
Sharing boundaries card from `$DW_LAB` template. Next: TI Handoff Lab.
Mission: sharing boundaries card
1) Name five sharing boundary literacy rows. 2) Disclosure gate linked to Module 8-1 TLP. 3) Intel retirement stub documented. 4) Write NEVER public restricted intel line.
