Title

The Tomcat server must protect log information from unauthorized deletion. (Cat II impact)

Discussion

If log 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. Application servers contain admin interfaces that allow reading and manipulation of log records. Therefore, these interfaces should not allow for unfettered access to those records. Application servers also write log data to log files which are stored on the OS, so appropriate file permissions must also be used to restrict access. Log information includes all information (e.g., log records, log settings, transaction logs, and log reports) needed to successfully log information system activity. Application servers must protect log information from unauthorized deletion.

Check Content

Check the permissions on all log files in CATALINE_HOME/logs: The permissions should be 640 or less permissive. If they are more permissive, this is a finding.

Fix Text

Configure the application server to protect log information from unauthorized deletion.
