Flyer - The exe-Guard project focuses on developing malware protection technology that takes advantage of the low amount of change required for control system devices after deployment to baseline and whitelist executing code and guard that it doesn't change. Whitelist antivirus methods establish a security baseline and automatically search for and deny deviations from that baseline, including attempts to inject malicious code or alter settings without proper authentication. The whitelist process also eliminates the need for frequent decommissioning to install security patches and signature updates in order to keep up with newly released malware. Instead, updates are only needed when firmware updates are preformed, allowing for the security baseline to be determined before the system returns to service.
