AI Technical Summary

Problems solved by technology

That is to say, the relative closeness of the industrial control system in the physical environment and the specificity of the software and hardware of the industrial control system will be broken. It will be possible to obtain more detailed information about the relevant industrial control system through the Internet or the intranet, and then In addition, the security awareness of enterprises operating industrial control systems is generally poor, which creates opportunities for hostile governments, terrorist organizations, commercial espionage, internal criminals, and external illegal intruders.

Embodiment Construction

[0035] 1 Eliminate all known security vulnerabilities: such as compiling software with the GS compilation option to eliminate buffer overflow vulnerabilities as much as possible; such as implementing the SEH verification mechanism; applying OS patches in time, upgrading the software to a safe version, etc.;

[0036] 2 Make sure the local protection function of the operating system is enabled

[0037] 2.1 Enable DEP

[0038] In Computer Properties ---> System ---> Performance Properties ---> Data Execution Prevention, turn on the DEP settings; enable the operating system, services, and applications to enable the DEP function.

[0039] 2.2 Using an operating system with ALSR enabled

[0040]Now the mainstream operating systems basically implement ALSR: OpenBSD, Linux2.6.12 and later, windowserver 2008, windows 7, Vista, Windows Server 2008R2, MAC OS X, IOS 4.3.

Abstract

The invention discloses a dynamic protection method of an implementation process of industrial configuration monitoring software, and belongs to the technical fields of industrial control and information. Firstly, the inherent space of a program is measured by means of a dynamic integrity measuring method, so that the program integrity and operation of the program in the condition that the program is not damaged are ensured, an alarm is sounded once it is found that the program integrity is damaged, and the program process is ended if necessary; secondly, extrinsic memory space is prevented in a memory allocation link, and injection of remote codes is prevented; by means of the two links, a monitoring and protection mechanism is provided for the process operation spatial environment, and it is ensured that the process operates in the correct state.

Description

technical field [0001] The invention belongs to the field of industrial control and the field of information technology, in particular to a process memory dynamic measurement and memory enhancement protection method. Background technique [0002] With the continuous cross-integration of industrialization and informatization, more and more information technologies have been applied to the industrial field. At present, industrial control systems have been widely used in electric power, water power, petrochemical, pharmaceutical, food manufacturing, transportation, aerospace and other industrial fields. Among them, more than 80% of the key infrastructure related to the national economy and people's livelihood rely on industrial control systems to realize automatic operations. The industrial control system has become an important part of the country's key infrastructure, and the security of the industrial control system is related to the country's strategic security.
