Authentication is the process of verifying the identity of a user or entity attempting to access a system, device, or network.
It involves validating the user’s identity and ensuring that the user has the necessary permissions to access the requested resource.
Authentication typically involves presenting some form of identification, such as a username and password, a security token, or biometric data.
Once the user’s identity is confirmed, the system can grant access to the requested resource.
Authentication is an essential component of information security, as it helps prevent unauthorized access and ensures that only authorized individuals can access sensitive information or systems.
It is often used in conjunction with other security measures such as access controls, encryption, and audit trails to create a comprehensive security framework.
