Verify Permissions on the Open vSwitch Persistent System ID
An XCCDF Rule
Description
To properly set the permissions of /etc/openvswitch/system-id.conf, run the command:
$ sudo chmod 0644 /etc/openvswitch/system-id.conf
Rationale
CNI (Container Network Interface) files consist of a specification and libraries for writing plugins to configure network interfaces in Linux containers, along with a number of supported plugins. Allowing writeable access to the files could allow an attacker to modify the networking configuration potentially adding a rogue network connection.
