Abstract:
With the rapid development of the Internet, Web services have become an indispensable part of modern society. By providing rich functionalities and convenient operations, Web services have greatly promoted the dissemination and sharing of information. However, with the widespread application of Web services, issues related to their security and performance have become increasingly prominent. How to ensure the security of Web services and improve their performance has become a hot topic of current research. This paper aims to explore the strategies for enhancing the security and optimizing the performance of Web services. By analyzing existing security threats and performance bottlenecks, corresponding solutions are proposed. Firstly, this paper reviews the major security threats faced by Web services, including SQL injection, Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), and analyzes the causes and hazards of these threats. Secondly, this paper discusses key aspects of performance optimization, such as caching mechanisms, load balancing, and database optimization, and proposes a series of specific optimization measures. Finally, through practical case studies and experimental verification, the effectiveness and feasibility of the proposed strategies are demonstrated. The research in this paper is of great significance for improving the security and performance of Web services, as well as ensuring the safety of user data and business operations.
