Checklist Summary:

This Trellix Application Control Security Technical Implementation Guide (STIG) is intended to provide guidance for Trellix Application Control on DOD workstation endpoints. Trellix Application Control is a portion of the Trellix Application/Change Control product. This STIG does not include guidance for servers or for Trellix Change Control. This STIG is only applicable in an Endpoint Security Solutions (ESS) managed environment. The current baseline version of Trellix Application Control is 8 and above. This STIG reflects requirements as they relate to Trellix Application Control 8 and above. Trellix Application Control is a Trellix ePolicy Orchestrator (ePO) managed software and is capable of blocking unauthorized applications and code on servers, corporate desktops, and fixed-function devices using centrally managed application allowlist(s). Trellix Application Control’s dynamic trust model and security features block advanced persistent threats (APTs) without requiring signature updates or list management. Trellix Application Control configuration for a centrally managed client is accomplished via ePO policies deployed to the client. While the Trellix Application Control can be configured by the Command Line Interface (CLI), the CLI is required to be disabled on a centrally managed Trellix Application Control installation. The Trellix Application Control STIG provides security policy and configuration requirements. The ESS STIG Overview provides an overview of all Trellix ESS products and services. Both documents can be referenced on the Cyber Exchange website at https://cyber.mil or https://public.cyber.mil.
