Network Access Control
What is Network Access Control (NAC)?
Network access control (NAC) is an approach to network and security management that enforces security, compliance and access control management policies to a network. It is a networking solution that allows only compliant, authenticated, and trusted devices and point nodes to access network infrastructure and resources. It also monitors and controls their activity once they are on the network.
HOW NAC SECURES YOUR NETWORK
Today, network access for multiple device types or temporary users is an expectation, not an exception. Modern Enterprise network requirements include:
- some level of access, no matter who or where you are
- access for guests such as sub-contractors, partners and remote employees
- access control for a new range of connected devices, for example smartphones, tablets and digital cameras
Allied Telesis LAN switches meet these emerging requirements, with comprehensive NAC features and integration. Used in conjunction with appropriate server-side and client-side software tools, they provide a remarkable level of control over the security status of the devices that connect to your network. The Allied Telesis NAC implementation is Trusted Computing Group’s Trusted Network Connect (TCG-TNC) standards-based, to guarantee interoperability with the major third-party suppliers of NAC software, such as Microsoft and Symantec. This provides customers with the confidence to create a comprehensive NAC solution from trusted vendors.
At the heart of using NAC for your network security are three key elements:
- no (or very limited) access without identification
- the quarantine and remediation of non-compliant devices
- setting the level of access to network resources based on a device’s authenticated identity
