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

When a system is attacked, one of the tasks of the attacker is to cover his tracks by deleting log files or log data. This enables the attacker to go unnoticed and to make later forensic analysis of the attack difficult, if not impossible. To protect the log information from deletion and discover the attacker quickly, the log files must be protected. This protection must take place at both the Administrator Console and at the OS level. Within the Administrator Console, the protection can be performed by giving users the proper roles and only giving log deletion to those that need that capability to perform their job duties. At the OS level, protecting the logs from deletion is performed by assigned the proper privileges to the log files and also giving OS users limited roles.
