SYSTEM AND METHOD FOR LIMITING DATA LEAKAGE IN AN APPLICATION FIREWALL

摘要

System and methods for connection processing with limited data leakage. The system records state associated with a connection request in a connection state engine, records state associated with a connection acknowledgement in the connection state engine, stores data sent after the connection acknowledgement in a buffer and determines, without a proxy, whether to allow or deny a connection as a function of the data stored in the buffer.

主权项

1. A system for determining whether to allow a connection between a first computer and a second computer, comprising:
a receiver, operable to receive data into a buffer from one of the first computer or the second computer; and a connection state engine, operable to:
record connection state information responsive to receipt of an acknowledgement by the second computer of a connection request from the first computer;read the data from the buffer;apply a security policy to the data; anddeny use of the connection between the first computer and the second computer without forwarding the data, based on the application of the security policy to the data.
