Client firewalls can be used to specify rules based on the path or checksum of the process that is trying to connect to the Internet. To make this possible, you must first add a device definition that specifies the values of the path, and/or checksum of the process. There are two variables that can be used in device definitions that is used by client firewalls. These are:
- clientfirewall-path
- clientfirewall-checksum
Only device definitions containing these variables can be used in the client firewall rules.
