Endpoint and Network Access Control: EDR, XDR, Antivirus, Captive Portals, 802.1X, and Posture (4.1)

This episode explains how endpoint protection and network access control help determine whether a device should be trusted, monitored, restricted, or blocked. Antivirus focuses on known malicious files and behavior, while endpoint detection and response provides deeper investigation, containment, and response capabilities on endpoints. Extended detection and response correlates signals across endpoints, networks, identity, cloud, and other sources to improve visibility. Captive portals control user access before allowing network use, 802.1X supports port-based network authentication, and posture checks evaluate device health, configuration, patch status, or management state. For Security+ scenarios, students should connect these tools to device trust, conditional access, containment, and reducing unmanaged endpoint risk.
