Purple › Module 1 › Lesson 1
Why Purple
Purple teaming literacy means red-blue collaboration vocabulary, detection engineering focus, and lab ethics on YOUR $PURPLE_LAB — not stranger-network attack simulations or unauthorized offensive campaigns.

Opening
Detection gaps hide in handoffs — Cyberlium teaches purple vocabulary and lab ethics on hosts YOU own, not attack simulations against networks you do not operate.
Purple teaming bridges offensive simulation and defensive detection — red exercises produce telemetry, blue engineers rules, purple coordinates feedback loops that close coverage gaps. Analysts need vocabulary to read exercise plans, Sigma drafts, and ATT&CK coverage matrices — not to run attack sims against stranger networks or third-party cloud tenants. Cyberlium Topic 35 teaches on $PURPLE_LAB — YOUR personal lab hosts, courseware simulation packs, and self-authored detection notes under $HOME/cyberlium-lab/t35-purple/. You will name purple concepts and lab boundaries — never stranger-network attack simulations or unauthorized offensive campaigns. Next: Lab Hosts Only.
1. What purple teaming covers (named)
Purple teaming includes collaborative exercise design, authorized simulation on owned assets, detection engineering, rule testing, coverage mapping, and feedback loops between red and blue functions. One governed exercise can validate ten detection rules when telemetry and expectations are documented.
Literacy means you can name these activities when reading a purple team charter or job description — not that you can run attack simulations against stranger ISP links or third-party SaaS tenants without authorization.

Reference sites: MITRE ATT&CK (https://attack.mitre.org/); Sigma (https://sigmahq.io/); Atomic Red Team (https://github.com/redcanaryco/atomic-red-team); Elastic detection rules (https://www.elastic.co/guide/en/security/current/rules-ui.html). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Who needs purple vocabulary
Detection engineers author Sigma and SIEM rules from exercise telemetry. Red team operators run scoped simulations on lab hosts. Blue analysts tune alerts from purple findings. Students practice scope and ethics on personal lab hosts before touching employer production exercises.
Cyberlium assumes YOU practice on $PURPLE_LAB — personal lab VMs, labeled courseware simulation packs, self-authored detection notes — not employer production networks without ticket scope or offensive sims against stranger networks.
3. What this topic will never call practice
Stranger-network attack simulations, running Atomic Red Team against third-party cloud tenants, sharing live victim breach replay scripts in public chat, impersonating adversaries against unauthorized targets, or deploying destructive payloads outside YOUR lab hosts.
Ship a sentence: Topic 35 here means detection engineering literacy on MY $PURPLE_LAB with lab hosts only. Next lesson: Lab Hosts Only.
4. What you ship: purple topic scope scoped to $PURPLE_LAB literacy
Write literacy vs unauthorized simulation in one paragraph. Dest = $PURPLE_LAB lab hosts. NEVER stranger-network attack sims. Notes chmod 600.
5. What you record before the next lesson

6. Wrong vs right: stranger networks vs YOUR purple lab
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Run attack sim against stranger cloud tenant 'for purple learning.' Treat Topic 35 as a free pass to simulate against third-party networks.
Right
Define purple literacy and name $PURPLE_LAB as the only practice surface. Next: Lab Hosts Only.
Mission: define Topic 35 for YOUR purple lab
1) Write literacy vs unauthorized simulation in one paragraph each. 2) Write a NEVER list (stranger-network attack sims, third-party tenant targeting, unauthorized offensive campaigns). 3) Name $PURPLE_LAB as your placeholder. Never aim attack simulations at networks outside your scoped lab hosts.
