Problems solved by technology

[0003] At present, relatively mature industrial control honeypot tools, such as Conpot, CryPLH, XPOT, etc., Conpot tools are easy to be identified because they cannot dynamically adjust simulation parameters; CryPLH is a high-interaction honeypot that can simulate PLC devices under the Siemens S7 protocol. Obtain the fingerprint of the TCP / IP operating system through Nmap, judge whether it is the same as the real PLC device, and thus be identified; XPOT can simulate Siemens SIMATIC S7 314C-2 PN / DP products, and can also simulate almost any other S7-300 / 400 Model, XPOT supports the execution of PLC programs, but requires compilation time before executing program instructions, and the supported program instructions are limited, so it is easy to be identified from the perspective of time and instructions

Abstract

One or more embodiments of the invention provide an industrial control honeypot method and device, and the method comprises the steps: carrying out the traffic monitoring of a message accessing the industrial Internet, and recognizing the abnormal traffic; analyzing the message of the abnormal traffic, and determining an attack behavior of an attacker; and performing behavior detection and / or feedback processing according to the attack behavior. According to the industrial control honeypot method and device, the concealment of the industrial control honeypot can be improved.

Description

technical field [0001] One or more embodiments of this specification relate to the field of information security technology, and in particular to an industrial control honeypot method and device. Background technique [0002] As an active security defense technology, honeypots are usually deployed on the public network to attract attackers to scan and attack them, capture attacker behavior data, and track and analyze attackers accordingly. Industrial control honeypots are honeypots used in the industrial Internet composed of industrial control systems. They can collect threatening attack behaviors and attack frequencies in the network environment, and help to discover security problems in industrial control systems in a timely manner. [0003] At present, relatively mature industrial control honeypot tools, such as Conpot, CryPLH, XPOT, etc., Conpot tools are easy to be identified because they cannot dynamically adjust simulation parameters; CryPLH is a high-interaction hone...
