Highlights

  • Focus on authz correctness (prevent IDOR / broken access control)
  • Threat model + mitigations mapped to practical controls
  • Evidence: test cases, logs, and defensive validation patterns

Audience

Coming soon.

Problem / Goal

Coming soon.

Approach

Coming soon.

Threats (What I design against)

  • Broken access control / IDOR
  • Token leakage and replay
  • Abuse via automation and rate-limit bypass attempts

Controls (How I mitigate)

  • Centralized authorization checks
  • Strict validation + safe error handling
  • Rate limits + logging for investigation

Evidence

WRITEUPWriteup (coming soon)(Planned)
Evidence links will be added as artifacts are published (screenshots, configs, scan results, writeups).

Next steps

  • Create the project writeup with concrete examples
  • Add test cases and screenshots
  • Add a threat model table mapped to controls
