이름: Improperly Preserved Integrity of Hardware Configuration State During a Power Save/Restore Operation
The product performs a power save/restore
operation, but it does not ensure that the integrity of
the configuration state is maintained and/or verified between
the beginning and ending of the operation.

잠재적 완화 방법
Phases : Architecture and DesignInside the IP, incorporate integrity checking on the configuration state via a cryptographic hash. The hash can be protected inside the IP such as by storing it in internal registers which never lose power. Before powering down, the IP performs a hash of the configuration and saves it in these persistent registers. Upon restore, the IP performs a hash of the saved configuration and compares it with the saved hash. If they do not match, then the IP should not trust the configuration.
Phases : Integration
Outside the IP, incorporate integrity checking of the configuration state via a trusted agent. Before powering down, the trusted agent performs a hash of the configuration and saves the hash in persistent storage. Upon restore, the IP requests the trusted agent validate its current configuration. If the configuration hash is invalid, then the IP should not trust the configuration.
Phases : Integration
Outside the IP, incorporate a protected environment that prevents undetected modification of the configuration state by untrusted agents. Before powering down, a trusted agent saves the IP's configuration state in this protected location that only it is privileged to. Upon restore, the trusted agent loads the saved state into the IP.
취약점 매핑 메모
근거 : 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.댓글 : 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-176 | Configuration/Environment Manipulation
An attacker manipulates files or settings external to a target application which affect the behavior of that application. For example, many applications use external configuration files and libraries - modification of these entities or otherwise affecting the application's ability to use them would constitute a configuration/environment manipulation attack. |
