Description
If audit data were to become compromised, competent forensic analysis and discovery of the true source of potentially malicious system activity would be difficult, if not impossible, to achieve. In addition, access to audit records provides information an attacker could use to their advantage. To ensure the veracity of audit data, the information system and/or the application must protect audit information from all unauthorized access. This includes read, write, copy, etc. Satisfies: SRG-APP-000118-DB-000059, SRG-APP-000119-DB-000060, SRG-APP-000120-DB-000061
