SECURING ACCESS

mode disables the port, not allowing any traffic to pass through. The drop mode allows the
port to remain enabled during a security violation and drop only packets that are coming
in from insecure hosts. This is useful when there are other network devices connected to
the MultiLink ML810 Managed Edge Switch. If there is an insecure access on the secondary
device, the MultiLink ML810 Managed Edge Switch allows the authorized users to continue
to access the network; the unauthorized packets are dropped preventing access to the
network.
Network security hinges on the ability to allow or deny access to network resources. This
aspect of secure network services involves allowing or disallowing traffic based on
information contained in packets, such as the IP address or MAC address. Planning for
access is a key architecture and design consideration. For example, which ports are
configured for port security? Normally rooms with public access (e.g. lobby, conference
rooms, etc.) should be configured with port security. Once that is decided, the next few
decisions are: Who are the authorized and unauthorized users? What action should be
taken against authorized as well as unauthorized users? How are the users identified as
authorized or unauthorized?
