DBMS Security

DBMS Security:

• Authentication: Verifying the identity of users before they can access the database, typically using usernames and passwords, biometrics, or two-factor authentication.
• Authorization & Access Control: Granting specific permissions (privileges) to authenticated users. This determines which data users can view or modify (e.g., read, write, delete).
• Encryption: Converting data into a coded format to prevent unauthorized users from reading it, both "in transit" (over the network) and "at rest" (on storage devices).
• Data Auditing: Tracking who accesses the database and what operations they perform. Audit trails help in detecting and investigating security breaches.
• Backup and Recovery: Regularly backing up data to ensure it can be restored in case of data loss due to hardware failure, cyber-attacks, or other disasters.
