20100077216METHOD FOR ENHANCING NETWORK APPLICATION SECURITY - A method for securing communications between a server and an application downloaded over a network onto a client of the server is disclosed. A first request is received from the client, and in response a session credential security token is generated and sent to the client. A second request is received from the client to download the application and includes the value of the session credential security token. The server verifies that the value of the session credential security token is valid and, if so, generates a second security token that is tied to the session credential security token. The second token is embedded in application code and then the application code is sent to the client. A subsequent request for data from the application running on the client includes the value of the session credential security token and the value of the embedded security token. Verification of validity of the values of the session credential security token and the second security token received with the data request then occurs at least in part by determining that the values are cryptographically tied to one another. Upon verification, the requested data is sent to the client.03-25-2010

20100332837WEB APPLICATION SECURITY FILTERING - User inputs and/or Uniform Resource Identifier (URI), historically and popularly referred to as Universal Resource Locator (URL), requests in a content description language are passed through a security service (Web application firewall or a reverse Web proxy server) that is placed in front of Web application servers in order to protect the servers from hacking attempts.
