Security needs to be provided to which category of data?

Data security is a fundamental aspect of information security that applies to all categories of data. This encompasses not just restricted or private data, but also information deemed illegal, as any handling of such data still needs to follow legal and ethical guidelines to avoid misuse and protect against potential repercussions.

Restricted data typically refers to sensitive information that requires a higher level of protection due to its confidential nature. Private data involves personally identifiable information (PII) that must be safeguarded to protect individuals' privacy rights. Illegal data, while problematic by nature, also necessitates security measures, as handling it irresponsibly could lead to legal issues and exposure to criminal liabilities.

Thus, securing all kinds of data—including restricted, illegal, and private—is essential to uphold data integrity, protect stakeholder interests, and comply with regulatory requirements. This holistic approach ensures that all data, regardless of its sensitivity or legality, is adequately protected against unauthorized access, breaches, and other security threats.
