Description
To ensure Solidcore clients are only configured to STIG and organization-specific settings, organization-specific ePO policies must be applied to all organization workstation endpoints. The McAfee Application Control installs with two Default Rules policies. The McAfee Default Rules policy includes the whitelist for commonly used applications to the platform. The McAfee Applications Default Rules policy include the whitelist for McAfee applications. Both of these policies are at the "My Organization" level of the System Tree and must be inherited by all branches of the System Tree. Organization-specific applications would be whitelisted with an organization-specific policy combined with the two Default policies into one effective policy.
