工业物联网（IIoT）背景下的PLC控制系统安全加固方案

摘要

随着工业物联网（IIoT）技术的迅速发展，传统的PLC控制系统逐渐面临越来越复杂的安全威胁。PLC作为工业控制系统的核心，承担着自动化生产、设备监控和实时控制等重要任务。PLC控制系统通常缺乏有效的安全防护，容易成为黑客攻击和恶意软件侵入的目标。本研究旨在探讨在工业物联网背景下，如何通过多种安全加固措施提升PLC控制系统的安全性。通过对现有安全漏洞的分析与评估，提出了一系列安全加固方案，涵盖网络隔离、身份验证、数据加密等措施，旨在构建更为安全的PLC控制系统架构，以保障工业生产的稳定性和安全性。

Abstract

With the rapid development of Industrial Internet of Things (IIoT) technology, traditional PLC control systems are gradually facing increasingly complex security threats. As the core of industrial control systems, PLCs undertake important tasks such as automated production, equipment monitoring, and real-time control. PLC control systems typically lack effective security protection, making them vulnerable targets for hacker attacks and malicious software intrusions. This study aims to explore how to enhance the security of PLC control systems through various security reinforcement measures in the context of IIoT. By analyzing and evaluating existing security vulnerabilities, a series of security reinforcement schemes are proposed, covering measures such as network isolation, authentication, and data encryption. The goal is to construct a more secure PLC control system architecture to ensure the stability and safety of industrial production.
