Abstract

Techniques for providing layer 4 transparent secure transport for end-to-end application protection are described herein. According to one embodiment, a packet of a network transaction is received from a client over a first network, where the packet is destined to a server of a data center having a plurality of servers over a second network. The packet includes a payload encrypted without encrypting information needed for a layer 4 of OSI (open system interconnection) layers of network processes. The layer 4 process is performed on the packet without having to decrypting the payload to determine whether the packet is eligible to access the destined server over the second network based on the unencrypted layer 4 information. Other methods and apparatuses are also described.
