Zero Trust Fit

Microservices security literacy names service identity, mTLS, API gateways, secrets management, and observability — draft microservice row on YOUR $ARCH_LAB before cloud reference patterns.

Microservices security literacy. $ARCH_LAB only. Original Cyberlium.

Monolith assumptions fail in service meshes — literacy teaches microservices security patterns so fictional org services on $ARCH_LAB get identity and boundary controls.

Microservices multiply trust boundaries — each service needs identity, authenticated inter-service calls, centralized secrets rotation, API gateway policy enforcement, and distributed tracing for security events. On Cyberlium you map fictional LAB-ARCH-001 services — example.local orders API, inventory worker — under $ARCH_LAB, not employer production Kubernetes exports without scope. Cyberlium writes microservice row on YOUR $ARCH_LAB — service name, identity method, inter-service control, observability note for one fictional LAB-ARCH-001 pair. Next: Cloud Reference Patterns.

1. Microservices security components (named)

Service identity: workload SPIFFE or IAM role on YOUR fictional cluster. mTLS: encrypted authenticated service-to-service on LAB-ARCH-001 mesh. API gateway: external authZ and rate limits at edge. Secrets: vault or managed secrets — no hardcoded keys in lab templates. Observability: security event correlation across services.

On $ARCH_LAB, write microservice row — service pair, identity, inter-service control, log/trace note.

Command guide

Try these commands — Microservices security components (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: grep, python3. Reference sites: C4 model (https://c4model.com/); Microsoft SDL (https://www.microsoft.com/en-us/securityengineering/sdl/); 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 microservices change architecture review

East-west traffic dominates — perimeter firewall alone misses service-to-service abuse. Shared service security vocabulary aligns platform and application teams. Documented identity patterns survive design review on lab templates.

Students draft lab microservice notes — production patterns follow platform engineering and change control.

3. Lab boundary

Forbidden: copying real employer service mesh config with live secrets into lab. Allowed: microservices security card — fictional services with $ARCH_LAB placeholders.

Ship: microservice security row for YOUR lab services. Next: Cloud Reference Patterns.

4. What you ship: microservices security row for $ARCH_LAB

Service pair, identity, inter-service control, observability. $ARCH_LAB named. chmod 600.

5. What you record before the next lesson

Date. Microservice row. $ARCH_LAB named. File t41-m05-l02-microservices-security.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: Hardcode API keys in lab template because 'it's fictional.' Skip service identity because 'internal only.'
Right: Write microservices security row for YOUR $ARCH_LAB fictional services. Next: Cloud Reference Patterns.
