Network Access Control Defined
NAC makes it possible to determine which users have permission to access a network, what they can see and who is restricted from accessing the network.
For instance, all employees within a company will require access to the company network. But not everyone should have permission to view sensitive data, such as the company’s financial information or proprietary data. Guests, such as contractors and freelancers, will only need limited access and control. For example, guests may be able to view documents but have no editing ability. Network access control is one method that companies can use to ensure that only employees who require access can gain access and to prevent malicious traffic from accessing the network.
