Authentication Failure Explained with Practical Examples

  Identification and Authentication Failures in Web Applications In modern web applications, authentication plays a critical role in protecting user accounts and sensitive data. Authentication is the process of verifying the identity of a user before granting access to a system or application. If authentication mechanisms are not implemented properly, attackers may exploit these weaknesses to gain unauthorized access. One of the major web security risks identified by the Open Web Application Security Project is Identification and Authentication Failures . This vulnerability occurs when applications incorrectly implement authentication and session management, allowing attackers to compromise accounts, steal data, or perform unauthorized actions. What is Authentication? Authentication is the process used to confirm that a user is who they claim to be. Most web applications implement authentication using login credentials such as: Username and Password One-Time Password (OTP)...
