A common security concern in many organisations is that users can easily connect infected or compromised machines into the network and cause widespread damage. Network Access Control (NAC) solutions were born to address this concern and ensure the health of the machines that connect to the network.
NAC, also called network admission control, is a method of bolstering the security of a network by ensuring the health of devices connecting to the network; NAC restricts the availability of network resources to endpoint devices that comply with a defined security policy.
Once the defined level of security posture is met, the computer can have access to pre-defined network resources according to the policies defined by the NAC. These policies are easily deployed on a “per device” level to either wired or wireless devices. Network access control is an ideal solution to help you optimise the productivity and accessibility of your network without compromising your enterprise security.
Defined policies can include, user group, device group, anti-virus protection level, system update level and configuration. While the computer is being checked by a pre-installed software agent, it can only access resources that can remediate (resolve or update) any issues. Once the policy is met, the computer is able to access network resources and the Internet, within the policies defined within the NAC system.
NAC has many benefits including, full network access-layer port lock-down and dynamic provisioning of access-layer ports. The team at Cube Cyber has extensive experience in the designing and implementing large-scale NAC deployments in both enterprise and medical grade network environments.
