With more than 1,200 faculty members, 7,900 staff and 27,000 students, UCI is the fourth-largest campus of the University of California system. Maintaining proper “defense in depth” security architecture against the rising number of new, complex, and elusive network-based attacks is a significant responsibility for UCI’s Network and Academic Computing Services (NACS) security group, Network Planning and Security. Trying to keep up with cleaning the University systems that have been hacked or compromised started to become a major issue, requiring additional personnel to deal with the security breaches. Network Planning and Security’s Computer Security Officer, Mike Iglesias, decided to upgrade the security infrastructure at the campus border to improve NACS’ ability to monitor network traffic while having no impact on network performance. As part of a comprehensive overhaul of UCI’s network security, building an intelligent monitoring layer with the use of a Top Layer IDS Balancer (3500 and 4508 product families) benefited the University in several ways.
