Vulnerability discussion

Filesystem logging, especially for NFS exported file systems, can be critical to detecting data misuse and possible hardware/system errors that may, otherwise, go unnoticed.

Check content

To enable NFS server logging the log option must be applied to all exported file systems in the /etc/dfs/dfstab. Perform the following to verify NFS is enabled. # share The preceding command will display all exported filesystems. Each line should contain a log entry to indicate logging is enabled. If the log entry is not present, this is a finding. If the share command does not return anything, then this is not an NFS server and this is considered not applicable. NFS version 4 does not support server logging. Verify NFS_SERVER_VERSMAX in /etc/default/nfs. # grep NFS_SERVER_VERSMAX /etc/default/nfs If NFS_SERVER_VERSMAX is commented out or set to any value but 2 or 3, this is a finding.

Fix text

Edit /etc/dfs/dfstab and add the log option to all exported filesystems. Run the shareall command for the changes to take effect. NFS version 2 or 3 must be forced by updating the NFS_SERVER_VERSMAX variable appropriately in /etc/default/nfs and restarting the NFS daemon.

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.
