How do you handle session management in backend systems?
Session management in backend systems involves the handling of user sessions to maintain state and ensure secure communication between the client and server. It typically involves techniques such as the use of cookies or tokens to identify and authenticate users, as well as server-side storage for session data. Implementing session management requires careful consideration of security, scalability, and performance. It is essential to protect against common vulnerabilities like session hijacking, session fixation, and session replay attacks. Additionally, session expiration, session data encryption, and secure session storage are crucial for ensuring the integrity and confidentiality of user sessions in backend systems.
