What is a security facility in DBMS?

A security facility in a Database Management System (DBMS) refers to the mechanisms and features designed to protect data from unauthorized access, breaches, and attacks. This includes authentication (verifying user identities), authorization (defining user permissions), encryption (protecting data in transit and at rest), and auditing (tracking access and changes to the data). These security measures ensure data integrity, confidentiality, and availability, ultimately safeguarding sensitive information within the database.
