Description: Token security refers to the measures implemented to protect access tokens and their unauthorized use in digital environments, especially in the cloud. A token is an object that represents authorization to access a specific resource, such as an API or a cloud service. These tokens are generated by an authentication server and are used to validate the identity of the user or application attempting to access a resource. Token security is crucial to prevent attacks such as identity theft, unauthorized access, and data manipulation. The main features of token security include encryption, token expiration, and access revocation. Encryption ensures that tokens cannot be read by unauthorized third parties, while expiration limits the time during which a token is valid, thus reducing the window of opportunity for a potential attack. Revocation allows administrators to immediately invalidate compromised tokens. In a world where applications and services are increasingly interconnected, token security has become an essential component of security architecture, ensuring that only authorized users and applications can access sensitive resources.
