Network access control
Network access control is the act of keeping unauthorized users and devices out of a private network. Organizations that provide occasional network access to certain devices or users outside the organization can use network access control to ensure that these devices comply with corporate security compliance standards.
Why is it important
Organizations are now accounting with the exponential growth of mobile devices accessing their networks and the security risks that come with them, it’s critical to have the tools that provide the visibility, access control, and compliance capabilities required to strengthen your network’s security infrastructure. A NAC system can deny network access to noncompliant devices, place them in a quarantined area, or give them only restricted access to computing resources, thus preventing insecure nodes from infecting the network.
