| Security Measures
AAA (Authentication, Authorization and Accounting)
– 276 –
◆ ND Snooping – Maintains an IPv6 prefix table and user address binding table.
These tables can be used for stateless address auto-configuration or for address
filtering by IPv6 Source Guard.
◆ IPv4 Source Guard – Filters IPv4 traffic on insecure ports for which the source
address cannot be identified via DHCPv4 snooping nor static source bindings.
◆ IPv6 Source Guard – Filters IPv6 traffic on insecure ports for which the source
address cannot be identified via ND snooping, DHCPv6 snooping, nor static
source bindings.
◆ ARP Inspection – 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.
◆ Application Filter – Discards CDP or PVST packets.
Note:
The priority of execution for the filtering commands is Port Security, Port
Authentication, Network Access, Web Authentication, Access Control Lists, IP
Source Guard, and then DHCP Snooping.
AAA (Authentication, Authorization and Accounting)
The authentication, authorization, and accounting (AAA) feature provides the main
framework for configuring access control on the switch. The three security
functions can be summarized as follows:
◆ Authentication — Identifies users that request access to the network.
◆ Authorization — Determines if users can access specific services.
◆ Accounting — Provides reports, auditing, and billing for services that users
have accessed on the network.
The AAA functions require the use of configured RADIUS or TACACS+ servers in the
network. The security servers can be defined as sequential groups that are applied
as a method for controlling user access to specified services. For example, when the
switch attempts to authenticate a user, a request is sent to the first server in the
defined group, if there is no response the second server will be tried, and so on. If at
any point a pass or fail is returned, the process stops.
The switch supports the following AAA features:
◆ Accounting for IEEE 802.1X authenticated users that access the network
through the switch.
