ADVANCED SECURITY

The Cisco Catalyst 4500 Series offers a rich set of industry-leading, integrated security features to proactively lock down your critical network

infrastructure. It reduces security risks with 802.1x-based user authentication, authorization, and accounting (AAA). The security policy enforcement

is uncompromised with the wire-rate, dedicated access control lists (ACLs) to fend off ever-increasing virus and security attacks. The Cisco Catalyst

4500 Series offers powerful, easy-to-use tools to effectively prevent the untraceable man-in-the-middle attacks, IP spoofing, and flooding attacks,

without any change to the end-user or host configurations. Secure remote access and network management is accomplished with the Secure Shell

(SSH versions 1 and 2) Protocol and SNMPv3.
