Episode 145: Network Access Control and Endpoint Protection (Domain 4)

Controlling access at the point of connection is one of the most effective ways to prevent unauthorized entry, and in this episode, we explore the implementation of Network Access Control (NAC) and endpoint protection systems. NAC evaluates devices before they’re allowed onto the network, verifying compliance with security policies—such as having up-to-date antivirus, system patches, or correct configurations—before granting access. We examine agent-based and agentless NAC deployments, posture assessments, and dynamic policy enforcement that adapts based on user role, location, or device health. We also cover Endpoint Detection and Response (EDR) tools that continuously monitor activity on endpoints, looking for signs of compromise, malware behavior, or lateral movement. When integrated, NAC and EDR provide a comprehensive access control and monitoring framework that allows organizations to enforce trust and visibility from the moment a device connects. Together, they ensure that every endpoint is both authorized and continuously evaluated.
