A method for performing security functions in a computer system hosting a network-facing server application includes receiving, by a service request processor, a service request to an application adapted to process the service request; responsive to the service request being a first request for the application to communicate over a network, processing the service request with a first process isolated in memory from the application; responsive to the service request being a second request for the application to access a physical storage device, processing the service request with a second process isolated in memory from the application; and responsive to a determination that the processed service request will not adversely affect the application, providing the processed service request to the application.

System and method for protecting service-level entities

A method for secure comparison of encrypted symbols. According to one embodiment, a user may encrypt two symbols, share the encrypted symbols with an untrusted third party that can compute algorithms on these symbols without access the original data or encryption keys such that the result of running the algorithm on the encrypted data can be decrypted to a result which is equivalent to the result of running the algorithm on the original unencrypted data. In one embodiment the untrusted third party may perform a sequence of operations on the encrypted symbols to produce an encrypted result which, when decrypted by a trusted party, indicates whether the two symbols are the same.
