What does the principle of least privilege entail?

The principle of least privilege is a fundamental concept in information security that involves giving users only the access rights that are essential for them to perform their job functions effectively. By minimizing user access to only what is necessary, organizations can significantly reduce the risk of unauthorized access to sensitive data and systems. This approach helps to limit potential damage in the event of an account compromise, as the attacker would only have access to a limited set of resources rather than all data and functionalities.

Implementing the principle of least privilege also enhances accountability, as it makes it easier to track user actions and determine who has accessed what information. Organizations can better protect their assets and comply with regulations that require strict data access controls. Overall, this principle is key to establishing a robust security framework and maintaining the integrity and confidentiality of sensitive information.
