Webcast: Application-layer firewalling -- Raise your perimeter IQ

Crystal I. Ferraro

Traditional perimeter firewalls perform Layer 3 and 4 port and protocol filtering, stateful inspection, NAT and VPN. Now, firewall vendors are introducing new technologies to perform application-layer filtering in both proxy- and stateful configurations. This new perimeter intelligence enables more granular intrusion prevention at the perimeter.

In this webcast, speaker Joel Snyder uncovers "hype vs. reality" of application-layer firewalling, exploring issues such as cost/benefit, technology maturity, configuration and administration challenges, and integration with existing intra-LAN security devices. You will learn: How application-layer firewalls can increase your perimeter defense; How app intelligence affects network performance; Similarities and differences between application-layer filtering, intrusion prevention and intrusion detection; When introducing application-layer filtering is a smart move for your organization -- and when the costs outweigh the benefits.

Speaker Joel Snyder is a senior partner with Opus One, a consulting firm in Tucson, Ariz. He has worked with networks since 1980, when he signed on with CompuServe Research and Development, and has been a member of the ISO and ITU communities, which write network standards, for over a decade. He is a frequent contributor to Information Security magazine as well as a member of the magazine's Test Alliance.
