Cisco Network Admission Control
Cisco Clean Access (CCA)
Washington State University (WSU) has implemented a network access system called Cisco Network Admission Control Appliance (NAC), also known as Cisco Clean Access (CCA), that services all computers connected to WSU's Residence Hall wired ("ResNet") and wireless ("WSU ResNet") networks and the Yakama Village Apartments.
CCA helps to protect the WSU campus network by checking to see that each Windows computer has an up to date antivirus program and current operating system updates prior to connecting to the network. Malicious software such as viruses and worms can cause data loss, data theft, and can render a computer unusable and affect network performance for other users. Cisco Clean Access ensures that computers connected to the network are protected, providing all users with a safer, more secure, and reliable network.
To use CCA, Windows users must install the CCA Agent software on their computers. The CCA Agent ensures that each computer has all necessary operating system updates, automatic updates enabled, and sufficient antivirus software installed. If the computer fails to meet one or more of these requirements, the CCA Agent helps the user acquire and install all necessary components. Computers are granted full access to the network after they have been fully updated and protected.
Users with other operating systems (MacOS, Linux, etc) will be required to authenticate on the network but an agent will not be required.
