Avoid object reutilization


The system must guarantee that objects (session ID, cookies, etc.) used in the authentication process cannot be reused (replay resistance).


In a system, it is necessary to prevent transmitted information from being reused by an attacker to impersonate an authorized user or server responses. Therefore, it is essential to verify the communications between the users and the system, thus avoiding a replay of any request that could affect the confidentiality, integrity and/or availability of the system.
