Disable Printer Browsing Entirely if Possible

An XCCDF Rule

Description

By default, CUPS listens on the network for printer list broadcasts on UDP port 631. This functionality is called printer browsing. To disable printer browsing entirely, edit the CUPS configuration file, located at /etc/cups/cupsd.conf, to include the following:

Browsing Off
BrowseAllow none

Rationale

The CUPS print service can be configured to broadcast a list of available printers to the network. Other systems on the network, also running the CUPS print service, can be configured to listen to these broadcasts and add and configure these printers for immediate use. By disabling this browsing capability, the system will no longer generate or receive such broadcasts.
