Abstract
A data processing apparatus can perform HTTP traffic monitoring and filtering of HTTP requests from clients and responses from servers. Example apparatus comprises a processor; a first network interface to a protected network; a second network interface to an external network; a core hypertext transfer protocol (HTTP) proxy coupled to the processor and coupled to a content cache, wherein the HTTP proxy is configured to receive an HTTP request from a client computer in the protected network, send the request to a network resource in the external network on behalf of the client, and receive an HTTP response from the network resource on behalf of the client computer; and a plurality of spyware scanning engines (SSEs), wherein each of the SSEs is coupled to stored content signatures, and wherein each of the SSEs is configured to detect a particular kind of malicious software in an HTTP response.
