Which security post is responsible for controlling access to Federal facilities?

The Access Control Post is specifically tasked with controlling entry to Federal facilities. This function involves verifying the identity of individuals seeking access, ensuring they have the necessary credentials or permission, and monitoring the flow of people entering and exiting the premises. By managing access, this post plays a crucial role in maintaining security and safeguarding sensitive areas from unauthorized entry.

While other posts such as the Control Center Operations Post and the Patrol and Response Post have important security roles, they focus more on monitoring and responding to incidents or situations rather than directly managing access. The Visitor Processing Post primarily handles the administrative aspects of visitor management, such as registration and providing visitor badges, but it does not encompass the broader responsibilities of access control that are specifically designated to the Access Control Post. Therefore, the Access Control Post is the most accurate answer, as it directly relates to the fundamental responsibility of controlling and monitoring access to Federal facilities.
