For displaying a node of a tree structure, a processor receives an anchor node creation command for a given node of a tree structure of nodes. The given node has one or more branches of parent nodes. The processor further removes the one or more branches of parent nodes and branches of sibling nodes of the given node from a display of the tree structure. In addition, the processor displays the given node as a topmost node of the tree structure.

Apparatus and method for displaying a node of a tree structure

An industrial control system hardened against malicious activity monitors highly dynamic control data to develop a dynamic thumbprint that can be evaluated to detect deviations from normal behavior of a type that suggest tampering or other attacks. Evaluation of the dynamic thumbprint may employ a set of ranges defining normal operation and reflecting known patterns of interrelationship between dynamic variables.

Security system for industrial control infrastructure using dynamic signatures

An industrial controller resistant to malicious attacks may provide a graduated response employing the elements of the control system to reduce access to the control system, log data, and announce intrusion based on a dynamically evolving assessment of the severity of any detected security issues.

Active response security system for industrial control infrastructure

An industrial control system providing security against tampering or modification generates periodic state thumbprints defining a state of control elements that may be forwarded to a security or safety appliance for comparison to a benchmark thumbprint indicating no tampering. The transmitted state thumbprint may capture not only programs but also configuration and environmental states of the control element.

Security system for industrial control infrastructure

A computer system, and related components including network interface devices, as well as methods for implementing and/or operating network interface devices to achieve network-based communications, are disclosed. In at least one embodiment, the computer system includes a network interface device, and a bus driver in communication with the network interface device. The bus driver has access to a plurality of driver programs, and the bus driver is capable of causing an installation of one such driver program on the network interface device. Also, in at least some embodiments, the bus driver facilitates communications between multiple network interface devices and an operating system of the computer system, and/or between the network interface devices and user mode applications implementing graphical user interfaces. Further, in at least some embodiments, the bus driver governs operation of the network interface devices, for example, in relation to power management and/or interrupt handling.
