The database security risk that occurs when data from a higher classification level is mixed with data from a lower classification level is known as a security breach.
This kind of security breach can happen if data from various classification levels is kept in the same database or on the same server, or if data from a higher classification level is sent to a device or system that isn't allowed to access it.
This kind of security lapse can result in serious repercussions, such as the unauthorized disclosure of private or sensitive information, harm to an organization's reputation, and legal liabilities. Additionally, it can weaken the database's overall security, leaving it open to attacks from bad actors.
Implementing appropriate security controls and procedures is crucial to ensuring that data from various classification levels is kept separate and secure and to preventing this kind of security risk.
