What approach does the principle of least privilege emphasize?

The principle of least privilege emphasizes access restrictions based on user roles. This principle asserts that users should be granted the minimum levels of access – or privileges – necessary to perform their job functions. By limiting access rights for accounts to only what is essential for their tasks, organizations can significantly reduce the risk of accidental or intentional misuse of sensitive information and resources. This approach helps to contain potential security breaches, as it restricts the amount of damage that could be inflicted by compromised accounts.

In this framework, each user role is examined to determine the specific permissions needed, ensuring that users cannot access or modify data outside their responsibilities. This principle is fundamental in creating a more secure network environment by minimizing vulnerabilities associated with excessive permissions and reducing the attack surface available to malicious actors.
