The ColdFusion log information must be protected from any type of unauthorized modification by having file ownership set properly.

Allowing any user to modify log messages provides a method for an attacker to hide his attack and go unnoticed. Log modification also makes forensic investigation difficult, if not impossible, as the information needed to recreate the event is either deleted or modified to hide what actions took place. Users are unable to modify log data through the Administrator Console, so the protection from modification is only relevant by enforcing protections from modification at the OS level. This is performed by properly setting file permissions and enforcing user logons that match each user's job role.
