Embodiment Construction

[0060] As mentioned earlier, the OT system faces the risk of network attacks, especially when accessing the OT system remotely, the OT system may face various network security threats due to the failure to take effective security protection measures.

[0061] The embodiment of the present invention provides an access control method and device, which are applied in a process of remote access to a system, such as an OT system, to provide an effective security protection method for the system. The method and device fully consider the practical requirements of the system operator, have the advantages of simple use, plug and play, and effectively reduce the security risk of the system.

[0062] Hereinafter, a system that uses OT technology is called an "OT system", and ICS and industrial control systems can be regarded as examples of OT systems.

[0063] The method and equipment provided by the embodiments of the present invention will be described in detail below with reference to the ac...

Abstract

The invention relates to the technical field of industrial safety, in particular to access control device and method, which can provide effective safety protection in the remote access process of a system. An access control device (50) comprises a front-end firewall (501), a first network port (51) is provided to be connected with a remote computer (20); a bastion host (502) connected with the front-end firewall (501); a rear-end firewall (503) connected with the bastion host (502) and provides a second network port (52) to be connected with the system (10); and a back-end firewall (503) which scans resources allowed to be remotely accessed in the system (10) through the second network port (52) and determines the resources which can be remotely accessed by a computer (20) from the resources; and the bastion host (502) provides information that the computer (20) can remotely access resources to the computer (20) through the front-end firewall (501) via the first network port (51). The invention has the advantages of safety and simplicity in use and plug-and-play performance.

Description

Technical field [0001] The present invention relates to the technical field of industrial security, in particular to an access control device, method, computer program product and computer readable medium. Background technique [0002] According to Gartner's definition, Operational Technology (OT) integrates hardware and software to directly monitor and / or control physical equipment to detect or trigger process changes or events in the enterprise. OT uses a computer to monitor or change the physical state of, for example, Industrial Control System (ICS). Among them, industrial control systems are facilities, systems and equipment based on computer implementations that are used to remotely monitor and / or control key industrial processes to achieve physical functions. The term "OT" is used to distinguish industrial control systems and traditional information technology (Information Technology, IT) systems in terms of technical implementation and function. Systems using OT technol...
