Description
If audit data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity is difficult, if not impossible, to achieve. In addition, access to audit records provides information an attacker could potentially use to his or her advantage. Application servers contain admin interfaces that allow reading and manipulation of audit records. Therefore, these interfaces should not allow for the unfettered access to those records. Application servers also write audit data to log files which are stored on the OS, so appropriate file permissions must also be used to restrict access. Audit information includes all information (e.g., audit records, audit settings, transaction logs and audit reports) needed to successfully audit information system activity. Application servers must protect audit information from unauthorized modification.

Check Text ( C-44117r1_chk )
Review the configuration settings to determine if the AS audit features protect audit information from unauthorized modification. Review file system settings to verify the AS sets secure file permissions on audit log files so as to prevent unauthorized modification. If the AS does not protect audit information from unauthorized modification, this is a finding.

Fix Text (F-40317r1_fix)
Configure the AS to protect audit information from unauthorized modification.
