FAQ: What Is A Nac In Cybersecurity?


What is NAC cyber security?

Network Access Control ( NAC ) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.

What does a NAC do?

Network Access Control ( NAC ) helps enterprises implement policies for controlling devices and user access to their networks. NAC can set policies for resource, role, device and location-based access and enforce security compliance with security and patch management policies, among other controls.

How does NAC authentication work?

This is what’s known as zero-trust security. During authentication, the NAC system prompts the user to enter credentials to verify their identity. This could be done through either a username/password check or a biometric scan.

How does Cisco NAC work?

NAC works with antivirus, patch management, and Personal Firewall software to assess the condition, called the posture, of a client before allowing that client network access. NAC helps ensure that a network client has an up-to-date virus signature set, the most current operating system patches, and is not infected.

What is NAC configuration?

NAC is part of the Cisco Self-Defending Network Initiative that helps you identify, prevent, and adapt to security threats in your network. NAC Layer 2 IP validation operates on edge switches but has different methods for validation initiation, message exchange, and policy enforcement from the NAC Layer 2 IEEE 802.1x.

Is network access control still relevant?

Hence, the resurrection of NAC continues to be upon us. At this point in 2019, over 60% of enterprise data is stored in cloud applications (public cloud, private cloud and a hybrid of both).
