Episode 143: Advanced Security Mechanisms — NAC, Honeypots, and Authentication Models

Beyond basic firewalls and access controls, advanced security mechanisms offer deeper visibility and proactive defense. In this episode, we explore Network Access Control (NAC), a system that evaluates a device’s health and compliance status before granting access to the network. NAC solutions can quarantine non-compliant systems, require updates, or redirect them to remediation zones. We explain how 802.1X, RADIUS, and posture assessments enable these capabilities.We also cover honeypots—decoy systems designed to lure attackers away from critical assets—and how they help in threat detection, analysis, and even legal investigations. Finally, we review different authentication models like federated identity, SSO (Single Sign-On), and token-based systems used in modern enterprise environments. This episode showcases the tools and concepts that go beyond the basics and into adaptive, context-aware security design.
