Prevent the connection of unregistered portable media
The connection of private devices, which may be infected or not up to date, is a very real threat for a business network. Connection management (via a Network Access Control - NAC) only allows connections from official devices that are known and documented.
By filtering connections to the network (NAC) at the switch, non-official devices are denied access. These devices cannot be used to gather information about the network infrastructure.
Deactivate the possibility of using non-encrypted media.
