脆弱性マッピングノート

理由 : 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.
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.

ノート

Issues related to state and cache - creation, preservation, and update - are a significant gap in CWE that is expected to be addressed in future versions. It likely has relationships to concurrency and synchronization, incorrect behavior order, and other areas that already have some coverage in CWE, although the focus has typically been on independent processes on the same operating system - not on independent systems that are all a part of a larger system-of-systems.
