  • Publication number: 20230418928
    Abstract: In one implementation, a method for providing security on an externally connected controller includes launching, by the controller, a security layer that includes a whitelist of permitted processes on the controller, the whitelist including (i) signatures for processes that are authorized to be executed and (ii) context information identifying permitted controller contexts within which the processes are authorized to be executed; determining, by the security layer, whether the particular process is permitted to be run on the controller based on a comparison of the determined signature with a verified signature for the particular process from the whitelist; identifying, by the security layer, a current context for the controller; determining, by the security layer, whether the particular process is permitted to be run on the controller based on a comparison of the current context with one or more permitted controller contexts for the particular process from the whitelist.

  • Publication number: 20230199010
    Abstract: In one implementation, a method for providing security on externally connected controllers includes receiving, at a reporting agent that is part of a security middleware layer operating on a controller, an indication that a process has been blocked; obtaining, by the reporting agent, trace information for the blocked process; determining, by the reporting agent, a code portion in an operating system of the controller that served as an exploit for the blocked process; obtaining, by the reporting agent, a copy of malware that was to be executed by the blocked process; generating, by the reporting agent, an alert for the blocked process that includes (i) the trace information, (ii) information identifying the code portion, and (iii) the copy of the malware; and providing, by the reporting agent, the alert to a network interface on the controller for immediate transmission to a backend computer system.
