Vulnerability discussion

Log files help establish a history of activities, and can be useful in detecting attack attempts or determining tuning adjustments to improve availability. Audit log content must always be considered sensitive, and in need of protection. Successful exploit of an application server vulnerability may well be logged by monitoring or audit processes when it occurs. By writing log and audit data to a separate partition where separate security contexts protect them, it may offer the ability to protect this information from being modified or removed by the exploit mechanism.

Check content

Obtain the Email Domain Security Plan (EDSP) and locate the audit logs assigned partition. By default the logs are located on the application partition in '\Program Files\Microsoft\Exchange Server\V14\Logging\'. If the log files are not on a separate partition from the application, this is a finding.

Fix text

Configure the audit log location to be on a partition drive separate from the application. Document the location in the EDSP.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
