What's the best way to secure user sessions against hijacking?
Asked on Feb 06, 2026
Answer
To secure user sessions against hijacking, use HTTPS to encrypt data in transit, implement secure cookies with the HttpOnly and Secure flags, and use session management techniques like regenerating session IDs after login.
Example Concept: Session hijacking occurs when an attacker gains unauthorized access to a user's session. To mitigate this risk, use HTTPS to encrypt data, ensuring that session cookies are transmitted securely. Additionally, set cookies with the HttpOnly and Secure flags to prevent access via JavaScript and ensure they are only sent over HTTPS. Regenerating session IDs upon login or privilege changes helps prevent fixation attacks.
Additional Comment:
- Always use HTTPS to protect data in transit and prevent eavesdropping.
- Set the
SameSiteattribute on cookies to prevent cross-site request forgery (CSRF). - Implement session timeouts and automatic logout for inactive sessions.
