СОВРЕМЕННЫЕ МЕТОДЫ AУТЕНТИФИКAЦИИ И AВТОРИЗAЦИИ В ВЕБ-ПРИЛОЖЕНИЯХ

Abstract

In the digital age, securing user identities and managing access rights have become the cornerstones of web application reliability. This article provides a comprehensive analysis of modern authentication and authorization methods, ranging from multi-factor authentication (MFA) to decentralized identity solutions. It explores the transition from traditional session-based security to stateless token-based protocols like OAuth2 and OpenID Connect. The study addresses key questions: What are the fundamental differences between authentication and authorization in modern architectures? How do biometric and passwordless technologies enhance user security? What challenges arise when implementing Zero Trust principles in government digital services? The paper highlights best practices for protecting sensitive data against credential stuffing and session hijacking attacks.
