4. SECURITY SERVER AND WAN OPTIMIZATION Cisco offers a scalable hardware based integrated SSL and compression solution SSL the industry standard for secure transport of traffic from client browsers to Web servers presents two critical challenges for today s e business infrastructure First because SSL encrypts data and headers it obscures the request specific information on which Layer 4 to 7 switching decisions are made Second SSL authentication places a high processing load for each SSL flow setup The Cisco CSS 11500 with integrated SSL modules meets both of these challenges by combining leading SSL acceleration technology with the Cisco WebNS technology In addition to superior price performance the SSL module simplifies the management of digital certificates The latest hardware module to be added to the Cisco CSS 11500 product line is capable of supporting both SSL acceleration and HTTP compression independently or simultaneously This combination of supporting SSL transaction and compression in the same module delivers the following benefits e Server based compression and SSL termination intensive processes that can rob server performance needed for computational tasks with this new module network designers can offload these processes to the Cisco CSS 11500 e Both secure and non secure client traffic can enjoy the improved server response times associated with HTTP compression e SSL and compression capacity can be scaled by
