How Cisco IT Upgraded Intrusion Detection to Improve Scalability and Performance

Overview

Comprehensive network security has no substitute. Firewalls are Cisco IT's first line of network defense, protecting against most intrusions from outside the network and intrusions into data centers. Firewalls are effective but limited in scope. Cisco IT needed more security at the network perimeter. Cisco deployed 35 Cisco IDS 4230 sensors worldwide. These sensors protect the network perimeter, alert IT staff when an intruder has penetrated the firewalls (or is within the firewalls), and captures data to help identify the IP address of the intruder.
