Security Features Overview


Security is a term that covers several different aspects of network use and operation.

One general type of security is control of the devices or users that can access the network. Ways of doing this include authenticating the user at the point of logging in, controlling access by defining limits on certain types of traffic, or protecting the operation of the switch itself. Security measures in this last category include routing policies that can limit the visibility of parts of the network or denial of service protection that prevents the CPU from being overloaded. Another general type of security is data integrity and confidentiality, which is provided by the MACsec protocol. Finally, management functions for the switch can be protected from unauthorized use. This type of protection uses various types of user authentication.
