Sessions
Last updated: Nov 3, 2026
Session management is very important for the security and authentication of users in the products of Fluid Attacks. Fluid Attacks uses JSON Web Tokens (JWT) as its session management mechanism. JWT is secure, efficient, and widely used in modern web applications.
Generation of session tokens
Fluid Attacks creates JWT tokens for valid user sessions. These tokens contain information such as the email of the user, the name, and a unique identifier (JTI). Fluid Attacks encrypts and signs these tokens before it returns them.
Secure encoding
Fluid Attacks uses JSON Web Encryption (JWE) to encode user information into tokens. This keeps the information confidential during transmission. Then, Fluid Attacks signs the encrypted payload with JSON Web Signature (JWS). This makes sure that the data has integrity and authenticity. This two-step process protects user data against tampering and unauthorized access.
Secure decoding
When Fluid Attacks receives a JWT token, it carefully decodes it and verifies its authenticity. With strict validation checks, Fluid Attacks makes sure that the token has integrity and is legitimate before it continues with user authentication. This method decreases the risk of token tampering or forgery.
Session verification
When a user gives a session token for authentication, Fluid Attacks strictly verifies its validity. Fluid Attacks makes sure that the token is authentic, that it belongs to the related user, and that it is not revoked. If the token is not valid, Fluid Attacks takes the applicable measures, for example, it raises exceptions and terminates the session.
Session removal
To keep security standards, Fluid Attacks gives mechanisms to revoke active session tokens. When Fluid Attacks marks tokens as invalid in its system, it terminates the related sessions. This prevents unauthorized access and improves the general security posture.
Session expiration
Each JWT token has a predefined expiration time. This time limit decreases the lifespan of the token. Thus, it gives less time for potential security threats, for example, identity theft or session hijacking. Token expiration makes the authentication mechanism of Fluid Attacks more resilient.
Concurrent sessions
The system of Fluid Attacks finds and manages concurrent user sessions. When a user starts a new session, Fluid Attacks does full checks to find concurrent sessions for the same user. If it finds more than one session, it takes proactive measures against potential security risks. For example, if a user logs in from a different browser, Fluid Attacks makes the previous session invalid to decrease the risk of unauthorized access. With this method, Fluid Attacks makes user security and data protection a priority at each stage of the session lifecycle.
In summary, the session management of Fluid Attacks includes strong token generation, secure encoding and decoding mechanisms, strict verification protocols, proactive session revocation measures, and effective mitigation for concurrent sessions. Fluid Attacks makes security a priority at each stage of the session lifecycle. Thus, it gives the highest protection to user credentials and sensitive data in its ecosystem.
