Security Engineering Bridge Review

Complete before Module 1. It diagnoses prerequisites; it does not waive required work.

Closed-book gate​

Explain process and memory isolation, TCP/TLS boundaries, DNS, authentication versus authorization, database transactions, cloud IAM, containers, CI/CD, observability, and incident SLOs.

Then:

  1. draw a service data flow and three trust boundaries;
  2. implement a negative authorization test;
  3. inspect a certificate and authenticated protocol;
  4. trace one request through application and infrastructure logs;
  5. package the test in a reproducible isolated environment.

Route gaps to Semesters 4, 5, 6, and 9. Submit diagnosis, remediation evidence, and readiness decision.
