Finding ID	Version	Rule ID	IA Controls	Severity

Description
Unauthorized changes to information can occur due to errors or malicious activity (e.g., tampering). Information includes metadata, such as security attributes associated with information. State-of-the-practice integrity-checking mechanisms (e.g., parity checks, cyclical redundancy checks, cryptographic hashes) and associated tools can automatically monitor the integrity of information systems and hosted applications. Security-relevant events include, for example, the identification of a new threat to which organizational information systems are susceptible and the installation of new hardware, software, or firmware. Transitional states include, for example, system startup, restart, shutdown, and abort. This requirement applies to integrity verification tools that are used to detect unauthorized changes to organization-defined information.
