Network Access Control (NAC) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.
Fortinet’s new network access controller, FortiNAC, diminishes the security risks associated with unsecured devices accessing the network by giving organizations total visibility of endpoints, users, trusted and untrusted devices and applications. Once visibility has been achieved, FortiNAC establishes dynamic controls that ensure that all devices, whether wired or wirelessly connected, are authenticated or authorized, and are subject to a context-driven policy that defines who, what, when and where connectivity is permitted. This ensures that only the appropriate people and devices can connect to and access appropriate applications, infrastructure and assets. Additionally, FortiNAC can enforce company policies on device patching and firmware version. FortiNAC also contains powerful network orchestration capabilities for delivering automated responses to identified threats and can perform threat containment in seconds, where a manual process could take days or weeks.
