What does the term "compartmentalization" imply in information security?

The term "compartmentalization" in information security specifically refers to restricting access to information based on the principle of need-to-know. This means that individuals within an organization are only granted access to information that is essential for them to perform their job duties. By implementing compartmentalization, organizations aim to enhance security by minimizing the risk of unauthorized access to sensitive data, which could lead to data breaches or other security incidents.

This approach helps to protect critical information and restricts the flow of data to only those who are authorized, thereby reducing the potential for breaches caused by insider threats or accidental disclosures. It fosters a more secure environment, ensuring that individuals cannot access information that exceeds their job requirements or security clearances.
