Discuss the role of confidentiality, integrity, and availability in the context of database security. Address the following in your post:
How can confidentiality be maintained, and what controls, like encryption or access restrictions, are effective?
How does proper database design support data integrity and prevent unauthorized modifications?
What techniques ensure data availability and reduce the risk of downtime?
In the field of cybersecurity, the CIA Triad (Confidentiality, Integrity, and Availability) serves as the foundational framework for protecting database environments. Balancing these three pillars is essential for any Advanced Practice Nurse, financial analyst, or IT professional who handles sensitive data.In the field of cybersecurity, the CIA Triad (Confidentiality, Integrity, and Availability) serves as the foundational framework for protecting database environments.

Encryption: This is the most robust defense. Encryption at Rest protects the data stored on physical disks (using algorithms like AES-256), while Encryption in Transit (using TLS/SSL) protects data as it moves across networks.
Access Restrictions: Implementing Role-Based Access Control (RBAC) ensures that users only see the data required for their specific job function. For example, a nurse may see clinical vitals, while a billing clerk only sees insurance information.
