Nutanix OS must have the fapolicyd.service installed and active.

Control of program execution is a mechanism used to prevent execution of unauthorized programs. Some operating systems may provide a capability that runs counter to the mission or provides users with functionality that exceeds mission requirements. This includes functions and services installed at the operating system level. Some of the programs, installed by default, may be harmful or may not be necessary to support essential organizational operations (e.g., key missions, functions). Removal of executable programs is not always possible; therefore, establishing a method of preventing program execution is critical to maintaining a secure system baseline. Methods for complying with this requirement include restricting execution of programs in certain environments, while preventing execution in other environments; or limiting execution of certain program functionality based on organization-defined criteria (e.g., privileges, subnets, sandboxed environments, or roles).

Verify in Nutanix OS that fapolicyd is installed and active using the following command. $ sudo yum list installed fapolicyd Installed Packages fapolicyd.x86_64 $ sudo systemctl status fapolicyd.service fapolicyd.service - File Access Policy Daemon Loaded: loaded (/usr/lib/systemd/system/fapolicyd.service; enabled; vendor preset: disabled) Active: active (running) If fapolicyd is not installed and active, this is a finding.
