Network Security Protocols Questions
Network access control (NAC) is a network security concept that involves implementing measures to control and manage access to a network. It ensures that only authorized users and devices are granted access to the network resources, while unauthorized users or devices are denied access. NAC typically involves the use of authentication mechanisms, such as usernames and passwords, digital certificates, or biometric authentication, to verify the identity of users and devices before granting access. Additionally, NAC may also involve the use of network access policies and enforcement mechanisms to enforce security rules and restrictions on network access. This helps to prevent unauthorized access, protect sensitive data, and maintain the overall security and integrity of the network.
