AUTHENTICATION PRINCIPLES AS SECURITY ASPECTS OF WEB DEVELOPMENT

This article examines modern authentication and authorization methods, emphasizing their critical role in web systems security. It estimates traditional approaches, such as Basic Authentication, and compares them to more advanced techniques like OAuth and JSON Web Tokens (JWT). The authors focus on the growing complexity of web systems, necessitating stronger and more flexible security mechanisms.Particular attention is paid to the weaknesses of password-based systems and the advantages of token-based solutions, with a strong emphasis on JWT as the most appropriate choice for the majority of current web development. The compact and self-contained nature of JWT, combined with its scalability and security, makes it a preferred method for both authentication and authorization in diverse web environments.The article also highlights the risks associated with token management, such as interception and misuse, while offering practical strategies for mitigating these threats. The authors states that, for most modern web systems, JWT provides a more efficient and secure alternative to traditional methods, balancing security needs with performance and convenience in use.In conclusion, the study recommends the adoption of JWT as a flexible and scalable solution that meets the security demands of evolving web systems. Practical recommendations are provided for the secure implementation of JWT to ensure the protection of user data and enhance overall cybersecurity.
