NAC solutions identify, authenticate, and assess the security posture of devices attempting to connect to the network, and subsequently grant or deny access based on predefined policies. NAC can also be employed for ongoing monitoring and enforcement of network security policies, allowing organizations to apply dynamic policies that account for user roles, device types, location, and other factors. NAC is useful for preventing unauthorized access, maintaining compliance, and detecting and mitigating potential security risks.
Guide on Network Access Control (NAC)
What is Network Access Control (NAC)? Network Access Control (NAC) is a security solution that enforces policy on devices that try to access network resources. By granting or denying network access based on a device's compliance with policy, it helps organizations secure their networks and protect sensitive data.
Why is it Important? NAC plays a critical role in ensuring that only authorized and compliant devices access your network resources. It helps to prevent security threats like malware, hacking, and data breaches.
How it works? NAC works by authenticating and authorizing devices before they can access network resources. It can either permit, deny, or restrict access based on the device's compliance level.
