It involves a set of technologies, protocols, and processes that verify the identity, trust, and compliance of devices and users before granting them network access. NAC solutions can authenticate users, check the security posture of their devices, and apply appropriate policies based on user roles, device types, and other factors. NAC improves the security of wireless and mobile devices by ensuring that only authorized and compliant devices can access sensitive resources, helping to prevent unauthorized access, malware infection, and data leakage.
Guide on Network Access Control (NAC)
In the fields of Computer Networking and Cybersecurity, Network Access Control (NAC) is a crucial concept. What is NAC?
