Các biện pháp giảm thiểu tiềm năng
Phases : Architecture and DesignEnsure that the design of volatile-memory protections is enough to prevent modification from an adversary or untrusted code.
Phases : Testing
Test the volatile-memory protections to ensure they are safe from modification or untrusted code.
Phương pháp phát hiện
Manual Analysis
Ensure the volatile memory is lockable or has locks. Ensure the volatile memory is locked for writes from untrusted agents or adversaries. Try modifying the volatile memory from an untrusted agent, and ensure these writes are dropped.Hiệu quả : High

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.

| CAPEC-456 | Infected Memory
An adversary inserts malicious logic into memory enabling them to achieve a negative impact. This logic is often hidden from the user of the system and works behind the scenes to achieve negative impacts. This pattern of attack focuses on systems already fielded and used in operation as opposed to systems that are still under development and part of the supply chain. |
