Description: Reauthentication is the process of verifying a user’s identity again after a session has expired. This mechanism is fundamental in Zero Trust security environments, where it is assumed that threats can exist both inside and outside the network. Reauthentication ensures that only authorized users maintain access to critical resources. In a zero trust context, reauthentication becomes an essential practice to mitigate risks, as it allows for continuous validation of the user’s identity and access level. This process may include credential verification, multifactor authentication, and other validation methods that ensure access to sensitive data is controlled and monitored. In the realm of identity and access management, reauthentication is implemented to protect information in various environments, where attacks can be more frequent. Additionally, in e-commerce and online services, reauthentication helps prevent fraud and unauthorized access, ensuring that transactions are conducted securely and reliably.
