Vulnerability discussion

Logging or auditing of failed access attempts is a necessary component for the forensic investigation of security incidents. Without logging there is no way to demonstrate that the access attempt was made or when it was made. Additionally a pattern of access failures cannot be demonstrated to assert that an intended attack was being made as apposed to an accidental intrusion.The IAO/NSO will ensure that all attempts to any port, protocol, or service that is denied are logged.

Check content

The reviewer will, with the assistance of the IAO/NSO, verify that all attempts to any port, protocol, or service that is denied are logged.

Fix text

Develop a plan to implement the logging of failed or rejected ports, protocols or services requests. The plan should include a projection of the storage requirements of the logged events. Obtain CM approval of the plan and execute it.

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.
