Security Overview
Network security is one of the most important aspects of any enterprise-class network. Security
provides authentication and authorization for both access to the network and management access to the
network devices. Network administrators must protect their networks from unauthorized external
access as well as from internal access to sensitive company information. Extreme Networks products
incorporate multiple security features, such as IP access control lists and virtual LANs (VLANs), to
protect enterprise networks from unauthorized access.
EPICenter provides multiple features that control and monitor the security features on Extreme
Networks products. Using EPICenter, you can set up VLANs, configure security policies, and monitor
security aspects of your network.
Management Access Security
Along with securing the traffic on your network, you must set up your network switches to allow only
authorized access to the switch configuration and traffic monitoring capabilities. This requires securing
the switch to allow only authenticated, authorized access, and securing the management traffic between
the switch and the administrator's host to ensure confidentiality.
