TCP_CVS invalid repository response

 

Code: p531

Severity: Notice

 

Description: CVS is the Concurrent Versions System, commonly used to help manage software development.

Impact: This may be an intelligence gathering activity or an attempt to connect to a CVS repository containing code not publicly available.

Corrective: Disable the CVS daemon in the file /etc/inetd.conf. Run the CVS daemon as a user other than root that does not have a valid login to the machine. Disable anonymous access to the cvs server where appropriate. Maintain checks on the password database and the CVS repository logs.
