A method, system and computer program product for retrieving both sensitive and non-sensitive content in a secure manner. After a proxy server establishes a secure connection between a client device and a web server, the client device receives the requested sensitive content, which includes an index file that contains a hash value that was generated by the web server. The web browser of the client device further issues a request to the proxy server to establish a non-secure connection to retrieve non-sensitive static content from the web server. After receiving the requested content, the web browser of the client device generates a hash value over the received content. If this generated hash value is equal to the hash value contained in the index file, then the web browser accepts the received non-sensitive static content. In this manner, both sensitive and non-sensitive content can be retrieved in a secure manner.

Retrieving both sensitive and non-sensitive content in a secure manner

A system, method and apparatus for securing communications between a trusted network and an untrusted network are disclosed. A perimeter client is deployed within the trusted network and communicates over a session multiplexing enabled protocol with a perimeter server deployed within a demilitarized zone network. The perimeter client presents requests to make available and communication initiation requests to the perimeter server which presents corresponding sockets to the entrusted network. The session multiplexing capabilities of the protocol used between the perimeter server and perimeter client permit a single communication session therebetween to support a plurality of communication sessions between the perimeter server and untrusted network. In the event data flows across the communication sessions are encrypted, decryption of the data flows is left to the components at the end points of the communication session, thereby restricting exposure of privileged information to areas within trusted networks.
