Foundations, Cryptography, Identity, and Authorization

Module Readiness: Learner-ready

The complete concept, adversarial practice, assessment, transfer, and source-routing path is available.

Selective Reading Rule​

The guide is the primary teacher. Full-book reading is not required; use the module reading guide and linked standards or primary sources to resolve a named question.

Competency​

Model adversaries and assets; use cryptographic primitives through safe protocols and libraries; design authentication, sessions, authorization, and key lifecycle.

Required Evidence​

  • asset inventory
  • protocol analysis
  • authorization matrix
  • key-rotation drill

Completion Gate​

Reproduce the threat or failure, implement the control, verify it with negative evidence, and state the remaining risk. Scanner output without triage does not count.

Source Policy​

Use current official standards and curated local book routes selectively. The completed guide must remain the primary teacher.
