EASURES
You can configure this switch to authenticate users logging into the system
for management access using local or remote authentication methods.
Port-based authentication using IEEE 802.1X can also be configured to
control either management access to the uplink ports or client access to
the data ports. This switch provides secure network management access
using the following options:
u
– Use local or remote authentication to configure access rights,
specify authentication servers, configure remote authentication and
accounting.
u
– Manually configure access rights on the switch for
specified users.
u
– Allows stations to authenticate and access the
network in situations where 802.1X or Network Access authentication
methods are infeasible or impractical.
u
- Configure MAC authentication and dynamic VLAN
assignment.
u
– Provide a secure web connection.
u
– Provide a secure shell (for secure Telnet access).
u
– Access Control Lists provide packet filtering for IP frames (based
on address, protocol, Layer 4 protocol port number or TCP control
code).
u
– Security feature that validates the MAC Address
bindings for Address Resolution Protocol packets. Provides protection
against ARP traffic with invalid MAC to IP Address bindings, which forms
the basis for certain “man-in-the-middle” attacks.
u
– Filters management access to the web, SNMP or Telnet
interface.
u
– Configure secure addresses for individual ports.
u
– Use IEEE 802.1X port authentication to control
access to specific ports.
u
– Filters untrusted DHCP messages on insecure ports
by building and maintaining a DHCP snooping binding table.
