How to prevent it (1 mitigation)

  1. Architecture and Design, Implementation, Testing

    - Security lock bit protections must be reviewed for design inconsistency and common weaknesses.

    - Security lock programming flow and lock properties must be tested in pre-silicon and post-silicon testing.
