物联网设备安全漏洞分析与防护对策
摘 要
随着物联网技术的快速发展，其设备安全漏洞问题日益凸显，对个人隐私、企业数据和国家安全构成严重威胁。本研究旨在系统分析物联网设备面临的安全风险，并提出有效的防护对策。通过文献综述和案例研究，本文首先梳理了物联网设备的主要安全漏洞类型，包括固件漏洞、通信协议缺陷和身份认证机制薄弱等。其次，采用模糊测试和静态代码分析相结合的方法，对典型物联网设备进行了深入的安全评估，发现了多个未知的高危漏洞。基于此，本文创新性地提出了一种基于区块链技术的分布式安全认证框架，该框架能够有效防止中间人攻击和数据篡改。研究结果表明，所提出的防护对策在提升设备安全性方面具有显著效果，特别是在抵御零日攻击和保护用户隐私方面表现突出。

SECURITY VULNERABILITY ANALYSIS AND PROTECTION COUNTERMEASURES OF INTERNET OF THINGS DEVICES
ABSTRACT
With the rapid development of the Internet of Things technology, the problem of its device security vulnerabilities is becoming increasingly prominent, posing a serious threat to personal privacy, enterprise data and national security. The purpose of this study is to systematically analyze the security risks faced by IoT devices and propose effective protective countermeasures. Through the literature review and case study, this paper first combs the main types of security vulnerabilities of IoT devices, including firmware vulnerabilities, communication protocol defects, and weak identity authentication mechanism. Secondly, the combination of fuzzy test and static code analysis was used to conduct an in-depth security evaluation of typical IoT devices, and several unknown high-risk vulnerabilities were found. Based on this, this paper innovatively proposes a distributed security authentication fr amework based on blockchain technology, which can effectively prevent middleman attacks and data tampering. The results show that the proposed protection countermeasures have a significant effect in improving the security of equipment, especially in resisting zero-day attacks and protecting user privacy.
