Explain a bit more

It ensures the confidentiality, integrity, and availability (often referred to as the CIA triad) of the data stored within the database. Why it's important: Confidentiality: Protects sensitive data from unauthorized access (e.g., personal information, financial data). Integrity: Ensures data remains accurate, consistent, and unaltered by unauthorized users. Availability: Ensures data is available when needed and prevents disruptions from threats like ransomware or DDoS attacks.
