Access Control is a fundamental security mechanism that regulates who can view or use resources in a computing environment. It ensures that only authorized users can access sensitive information, thereby protecting data integrity and confidentiality. Access control can be implemented through various methods, including passwords, biometric scans, and security tokens. In addition to protecting data, access control helps organizations comply with regulations and standards by enforcing policies that dictate user permissions. By managing access rights effectively, organizations can minimize the risk of data breaches and unauthorized access, ensuring a safer digital environment for all users.
