Embodiment Construction

[0047] The purpose of the present invention is to provide an audit method and system for a manufacturing execution system, so as to ensure the data security of the manufacturing execution system.

[0048] In order to make the above objects, features and advantages of the present invention more comprehensible, the invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] Such as figure 1 As shown, the present invention provides a manufacturing execution system audit method, the audit method includes the following steps:

[0050] Step 101, based on the trusted execution environment on the manufacturing execution system, collect login user identity information.

[0051] When the MES is started, the TEE module will automatically run, and when the user sends an application for operation authority through the system's interactive interface, the client will pop up the user login interface.

[0052] Step 102,...

Abstract

The invention discloses an auditing method and system for a manufacturing execution system, and the method comprises the following steps: collecting the identity information of a login user based on atrusted execution environment on the manufacturing execution system; performing matching verification on the login user identity information and historical user identity information stored in a trusted execution environment to obtain a verification result; when the verification result is passed, giving a management authority of the login user to the audit log; when the verification result does not pass, judging whether the verification failure frequency is less than a preset threshold value or not: if so, returning to the step of 'acquiring login user identity information based on a trusted execution environment on the manufacturing execution system', and continuing to verify; if not, setting the verification failure frequency to be 1, giving an alarm and locking the user interaction interface. And when the user identity information is unknown, the user operation interface is automatically alarmed and locked, so the safety coefficient of the system for information management is greatly improved.

Description

technical field [0001] The invention relates to the technical field of protection of manufacturing execution systems, in particular to an audit method and system of manufacturing execution systems. Background technique [0002] Manufacturing Execution System (MES), as an important part of the intelligent manufacturing industry, is an integration of real-time production information and an optimization system of the production process. The management and control of MES involves the planning and execution of the production process, which requires real-time dynamic monitoring during the production execution process, and coordination and adjustment according to the monitoring information, so as to make the production process run stably. [0003] The MES audit system meets the above requirements. It can collect the log information of the factory's network devices, hosts, operating systems, and user business systems in real time and continuously, assist administrators in analysis a...
