Các biện pháp giảm thiểu tiềm năng

Phases : Architecture and Design
Security identifier decoders must be reviewed for design consistency and common weaknesses.
Phases : Implementation
Access and programming flows must be tested in pre-silicon and post-silicon testing in order to check for this weakness.

Ghi chú ánh xạ lỗ hổng

Lý do : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Bình luận : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
