The Fapolicy module must be configured to employ a deny-all, permit-by-exception policy to allow the execution of authorized software programs and to prevent unauthorized software from running.
Utilizing a whitelist provides a configuration management method for allowing the execution of only authorized software. Using only authorized software decreases risk by limiting the number of potential vulnerabilities. Verification of whitelisted software occurs prior to execution or at system startup. Proceed with caution with enforcing the use of this daemon. Improper configuration may render the system non-functional. The "fapolicyd" API is not namespace aware and can cause issues when launching or running containers.
fapolicyd needs be configured so that users cannot give access to their home folders to other users.
Users' home directories/folders may contain information of a sensitive nature. Non-privileged users should coordinate any sharing of information with a System Administrator (SA) through shared resources. fapolicyd can confine users to their home directory, not allowing them to make any changes outside of their own home directories. Confining users to their home directory will minimize the risk of sharing information.
The fapolicyd package can be installed with the following command:
$ sudo dnf install fapolicyd
fapolicyd (File Access Policy Daemon) implements application whitelisting to decide file access rights.
The File Access Policy service should be enabled.
The fapolicyd service can be enabled with the following command:
$ sudo systemctl enable fapolicyd.service
