潜在的な緩和策
Phases : Architecture and Design
Identify data that needs to be protected from swapping and choose platform-appropriate protection mechanisms.
Phases : Implementation
When using potentially risky functions such as mlock() or VirtualLock(), check return values to ensure that locking operations are successful.
脆弱性マッピングノート
理由 : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
コメント : 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.
