Abstract
An embedded security processor is used in conjunction with a main processor to provide security for a computer system that is accessible via a computer network. In a preferred embodiment of the present invention, an expansion board is provided that has an embedded security processor dedicated to network communications security tasks. The embedded security processor is controlled by the main processor and intercepts all communications from external untrusted or unverified network systems (i.e., unsecure networks) and verifies that the attempted communication is permissible before allowing the external network communication traffic to access the main processor, or other networked computer resources accessible via a secure network.
