What verifies a user's right to access a computer and data?

A user's right to access a computer and its data is typically verified through authentication methods such as usernames and passWords, biometric scans, or security tokens. Additionally, authorization controls determine what level of access a user has based on their role or permissions. Together, these mechanisms ensure that only authorized individuals can access sensitive information and systems. Regular audits and monitoring also help maintain security and verify compliance with access policies.
