Abstract
A data center provides secure handling of HTTPS traffic using backend SSL decryption and encryption in combination with a load balancer such as a content switch. The load balancer detects HTTPS traffic and redirects it to an SSL offloading device for decryption and return to the load balancer. The load balancer then uses the clear text traffic for load balancing purposes before it redirects the traffic back to the SSL offloading device for re-encryption. Thereafter, the re-encrypted traffic is sent to the destination servers in the data center. In one embodiment, the combination with the back-end SSL with an intrusion detection system improves security by performing intrusion detection on the decrypted HTTPS traffic.
