STRIDE Named
STRIDE named literacy covers Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, and Elevation of privilege — map STRIDE row on YOUR $ARCH_LAB fictional component for design review.

STRIDE named literacy. $ARCH_LAB only. Original Cyberlium.
Opening
Threat categories without names scatter review — literacy teaches STRIDE vocabulary so fictional org components on $ARCH_LAB get structured threat analysis for defensive design.
STRIDE — Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, Elevation of privilege — organizes threat thinking for architecture and design review. On Cyberlium you apply STRIDE to fictional LAB-ARCH-001 components — lab API gateway, example.local auth service — to document mitigations, not to draft attack cookbooks against live targets. Cyberlium writes STRIDE row on YOUR $ARCH_LAB — component name, one STRIDE category, example mitigation for LAB-ARCH-001. Next: Trust Boundaries.
1. STRIDE categories (named)
Spoofing: fake identity on YOUR fictional auth endpoint. Tampering: unauthorized data change in transit or at rest. Repudiation: missing audit trail on LAB-ARCH-001 admin action. Information disclosure: data leak across trust boundary. Denial of service: availability attack on example.local service. Elevation of privilege: gaining unauthorized role.
On $ARCH_LAB, write STRIDE row — component, category, mitigation example for one fictional element.
Command guide
Try these commands — STRIDE categories (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: curl, grep. Reference sites: Microsoft STRIDE (https://learn.microsoft.com/en-us/azure/security/develop/threat-modeling-tool); OWASP Threat Modeling (https://cheatsheetseries.owasp.org/cheatsheets/Threat_Modeling_Cheat_Sheet.html); Microsoft SDL (https://www.microsoft.com/en-us/securityengineering/sdl/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Why STRIDE supports architecture review
Design reviews need shared threat vocabulary — STRIDE maps categories to control types. Documented mitigations survive sprint and architecture board questions on lab templates. STRIDE here means defensive analysis — not offensive exploit steps against real systems.
Students draft lab STRIDE notes — production threat models follow org methodology and authorized scope.
3. Lab boundary
Forbidden: converting STRIDE notes into step-by-step attack cookbook against live domains. Allowed: STRIDE named card — category and mitigation with $ARCH_LAB fictional component.
Ship: STRIDE row for YOUR lab component. Next: Trust Boundaries.
4. What you ship: STRIDE row for $ARCH_LAB
Component, STRIDE category, mitigation example. $ARCH_LAB named. chmod 600.
5. What you record before the next lesson
Date. STRIDE row. $ARCH_LAB named. File t41-m04-l01-stride-named.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
Write STRIDE as exploit walkthrough against real company. Skip mitigation column entirely.
Right
Write STRIDE row for YOUR $ARCH_LAB fictional component. Next: Trust Boundaries.
Mission: draft STRIDE on YOUR lab component
1) Name one fictional LAB-ARCH-001 component. 2) Pick one STRIDE category. 3) Write defensive mitigation example. 4) chmod 600.
