Abstract
With the rapid development of information technology, network security issues have become a global focus of attention. This article explores the importance, current status, and improvement strategies of network security protocols from the perspective of network security protocols, aiming to enhance the security and reliability of network transactions. Firstly, the article outlines the basic concepts, main functions, and mainstream protocols of network security protocols such as SSL/TLS, IPsec, and DNSSEC. Furthermore, the importance of network security protocols was analyzed, highlighting their critical role in defending against network threats, adapting to technological developments and changes in user needs, and maintaining stable operation in cyberspace. The article further analyzes network security protocols in detail from both security and performance perspectives, including key points such as encryption algorithms, identity authentication, data integrity, transmission efficiency, and resource consumption. Through case analysis, successful and failed cybersecurity practices have been revealed, providing empirical support for theory. In the problem diagnosis section, this article discusses in detail the technical and management issues of network security protocols, such as encryption algorithm vulnerabilities, identity authentication vulnerabilities, key management risks, incomplete security policies, weak security awareness, and lack of security auditing. In response to these issues, the article finally proposes a series of improvement strategies. On a technical level, it is recommended to optimize encryption algorithms, enhance identity authentication mechanisms, and innovate key management. At the management level, emphasis is placed on improving security policies and processes, enhancing security awareness and training, and strengthening security audits and monitoring. This study not only systematically analyzes the current status and challenges of network security protocols, but also proposes specific improvement measures, aiming to provide guidance for network security practices and promote the stability and security of the network environment. Through continuous technological innovation and policy improvement, we are expected to build a more secure and reliable cyberspace, protect user information from threats, and promote the healthy development of the digital economy.
