Data Security: Encryption ensures that even if unauthorized access to the database occurs, the data remains protected and unreadable without the decryption keys. Data Confidentiality: Highly sensitive data, such as personal information, financial records, or classified information, can be kept confidential through encryption. Data Privacy Compliance: Encryption is often a requirement for compliance with data privacy regulations, such as GDPR, HIPAA, or PCI DSS, when handling sensitive information. Protection Against Insider Threats: Even authorized database administrators or personnel cannot access the sensitive data without proper authorization and keys. Data at Rest and Data in Transit: Encryption can be applied to both data at rest (stored data) and data in transit (data transferred between systems), providing comprehensive security.
