Network Access Control

Network Access Control

Wireless access points, conference room ethernet ports, travelling laptops.  These are all entries into your network *behind* your firewalls.  And they bring risk.  Malicious activity, unknown programs, viruses, all can be released into the corporate network by simply connecting to it.  Or, corporate confidential information can be taken out of the network by connecting a malicious computer and downloading from the network file servers.

 

Network Access Control (NAC) products (also referred to as Network Admission Control, Network Access Protection (NAP), or Network Quarantine) protect networks by authenticating and authorizing users and computers prior to granting access to the network.  The implementation by each product varies widely, using solutions such as DHCP servers, VPNs, or switch hardware.  Some solutions require endpoint software be installed on each client.
