How do I handle and prevent session fixation attacks in my web application?
Session fixation attacks are a type of security vulnerability in which an attacker can hijack a user’s session by fixing or setting the session ID prior to the user logging in. Here are some steps you can take to handle and prevent session fixation attacks in your web application: 1. Regenerate session ID: After a user logs in or changes their privilege level, it is recommended to regenerate the session ID to mitigate the risk of session fixation attacks. This can be done by calling the appropriate function provided by your programming language or framework. 2. Expire sessions: Implement a session expiration mechanism that terminates sessions after a period of inactivity. This reduces the window of opportunity for an attacker to exploit session fixation vulnerabilities. 3. Secure session storage: Use secure session storage mechanisms to protect session data from unauthorized access. Avoid storing sensitive information in plain text and ensure the session data is encrypted or hashed. 4. Implement secure coding practices: Follow secure coding
