VCPG-67-000005 - VMware Postgres database must protect log files from unauthorized access and modification.

Details

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 potentially use to his or her advantage.



To ensure the veracity of audit data, the information system and/or the application must protect audit information from any and all unauthorized access. This includes read, write, copy, etc.
