Abstract: The present disclosure provides systems and methods for increasing the cybersecurity of a control subject of an industrial technological system. In an exemplary aspect, the method comprises installing a protected Operating System (OS) on a control subject of the industrial technological system, receiving, by the protected OS, a plurality of log files from the control subject, analyzing, by the protected OS, the plurality of log files to determine if a suspicious action has been applied to the control subject, wherein the control subject is configured to apply a controlling action to the object of control, intercepting, by the protected OS, network packets transmitted by an application launched in a guest OS to the control subject, and preventing, by the protected OS, an interaction between the application and the control subject, in response to determining that the suspicious action has been applied to the control subject.

Abstract: In a computer system having a plurality of software components, a security system for controlling interactions between the software components, the security system including at least one constraint associated with the interaction; and at least one attribute associated with the software components. The attributes and interaction parameters are bound to the constraint. The security system reaches a verdict permitting or forbidding the interaction, by resolving the constraint, based on value of the attribute and values of the parameters. The security system uses constraints and attributes specified during different life stages of each software component, where constraints are incrementally added during each subsequent life stage.
