The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack the required granularity

How to prevent it (1 mitigation)

  1. Architecture and Design, Implementation, Testing

    - Access-control-policy protections must be reviewed for design inconsistency and common weaknesses.

    - Access-control-policy definition and programming flow must be tested in pre-silicon, post-silicon testing.
