Fail Secure
Privacy by design literacy names data minimization, purpose limitation, default privacy settings, and placeholder data classes — document privacy row on YOUR $ARCH_LAB; educational, not legal advice.

Privacy by design literacy. $ARCH_LAB only. Original Cyberlium.
Security architecture without privacy defaults over-collects — literacy teaches privacy-by-design principles for fictional org processing on $ARCH_LAB with placeholder data only.
Privacy by design embeds data protection into architecture — collect minimum necessary, limit use to stated purpose, default to restrictive sharing, encrypt sensitive placeholders, document retention. On Cyberlium you use fictional data classes on LAB-ARCH-001 templates — never real customer PII, EU citizen records, or employer live ROPA exports in lab notes. Cyberlium writes privacy row on YOUR $ARCH_LAB — processing activity, placeholder data type, minimization control, retention note for one fictional LAB-ARCH-001 service. Next: SBD Lab.
1. Privacy by design principles (named, educational)
Minimization: collect only fields needed for fictional LAB-ARCH-001 feature. Purpose limitation: use data only for labeled training scenario. Defaults: restrictive sharing on new fictional accounts. Retention: delete placeholder records on lab schedule — consult counsel for real obligations.
On $ARCH_LAB, write privacy row — activity, placeholder data class, minimization control, retention sentence.

Try these commands — Privacy by design principles (named, educational)
═══ 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

Primary tools to practice this lesson: grep, python3. Reference sites: NIST Zero Trust (https://csrc.nist.gov/publications/detail/sp/800-207/final); Microsoft Zero Trust (https://learn.microsoft.com/en-us/security/zero-trust/); OWASP ASVS (https://owasp.org/www-project-application-security-verification-standard/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Why privacy belongs in architecture not bolt-on
Retrofit anonymization on wide tables costs more than narrow schema at design. Privacy impact discussions start with processing inventory on fictional org templates. Documented defaults survive design review sampling on lab artifacts.
Students draft lab privacy notes — production programs follow DPO and legal review.
3. Lab boundary
Forbidden: using real personal data in lab templates, claiming Cyberlium satisfies legal privacy duties. Allowed: privacy by design card — educational vocabulary with $ARCH_LAB placeholder data only.
Ship: privacy by design row for YOUR lab service. Next: SBD Lab.
4. What you ship: privacy by design row for $ARCH_LAB
Processing activity, placeholder data, minimization, retention. $ARCH_LAB named. chmod 600.
5. What you record before the next lesson
Date. Privacy row. $ARCH_LAB named. File t41-m03-l03-privacy-by-design.txt chmod 600.
6. Wrong vs right: offensive playbooks vs YOUR threat models
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
- Wrong: Paste real customer emails into lab processing inventory. Skip retention because 'lab data doesn't matter.'
- Right: Write privacy by design row for YOUR $ARCH_LAB. Next: SBD Lab.
Mission: draft privacy by design on YOUR lab
1) Name one fictional LAB-ARCH-001 processing activity. 2) Use placeholder data class only. 3) Write minimization and retention controls. 4) chmod 600.
