Welcome to Shree Learning Academy! In this video, we delve into the essential concept of Network Access Control (NAC) and its significance in managing access to systems and environments by enforcing robust security policies. Join us as we explore the objectives of NAC, including thwarting zero-day attacks, ensuring consistent security policy enforcement, and leveraging user identities for access control.

Discover how NAC serves as an automated system for real-time detection and response, keeping all monitored systems up to date with patches, updates, and the latest security configurations. Gain insights into the deployment options of NAC, including pre-admission and post-admission approaches, and understand how NAC can incorporate elements from both philosophies to meet specific deployment requirements.

Explore the considerations involved in choosing between a client/system agent or agentless approach in implementing NAC. Understand the differences between out-of-band and in-band monitoring methods and the challenges associated with remediation, quarantine, or captive portal strategies.

In a typical agent-based NAC system, we explore the process of installing NAC monitoring agents on managed systems and how these agents ensure compliance by comparing system configurations against baseline requirements. Learn how non-compliant systems are placed in a quarantined subnet for remediation, and how NAC agents bring systems into compliance before seamlessly reintegrating them into the production network.

Discover the NAC products and offerings from industry-leading organizations such as Cisco, McAfee, Symantec, and others. Additionally, we highlight the availability of open-source solutions in the market.

Understand the distinction between dissolvable and permanent NAC agents and their respective functionalities. Learn how NAC systems conduct host health checks to evaluate the security and performance status of monitored systems, enabling trend monitoring and baseline establishment.

Explore the differences between agent-based and agentless NAC systems, their advantages, and considerations. Gain insights into the volume of data provided by agent-based systems and the reliability of data provided by agentless systems.

Join us on this educational journey to master the intricacies of Network Access Control (NAC) and enhance your organization's security infrastructure.
