Abstract:
1. A system for providing protection from exploits to devices connected to a network, comprising: (a) a content filter that receives a message that is directed to at least one of the devices and that includes a header, a body, and an attachment, wherein the content filter determines an encapsulation that has been applied to the attachment prior to the system receiving the message and unencapsulates the attachment; (b) a decompression component that is coupled to the content filter and that performs at least one decompression of the attachment when the attachment is compressed; (c) a scanner component that is coupled to the decompression component and that determines whether the header includes an exploit, wherein exploit protection software from at least two vendors is employed and wherein the header includes a field having a defined size and the scanner determines that the header includes the exploit when a size of data in the field is other than the defined size; (d) a quarantine component that is coupled to the scanner component and that holds the message when the message includes an exploit; and (e) a device that receives messages that are directed to the network and that employs at least the scanner component to provide exploit protection for at least one of the messages.
