Which of the following are the levels of public or commercial data classification system? Each correct answer represents a complete solution. Choose all that apply.

Sensitive is a common classification for data that requires protection due to privacy concerns or potential harm if disclosed, but is not as critical as confidential.

Private data is typically personal information or data restricted to specific individuals or groups within an organization, requiring protection against unauthorized access.

Unclassified is a common classification level primarily used in government or military contexts, not typically in public or commercial systems.

Confidential data represents information that, if disclosed, could cause significant harm to an organization or individuals, thus requiring stringent controls.

Secret is a high-level classification typically reserved for government or military information whose unauthorized disclosure would cause serious damage to national security.

Public data is information that can be freely shared and accessed by anyone without causing harm to the organization or individuals, requiring minimal protection.
