What principle ensures that users have the minimum necessary access to perform their tasks?

The principle that ensures users have the minimum necessary access to perform their tasks is the Principle of Least Privilege. This principle is fundamental in cybersecurity and access management, as it limits a user's access rights to only those necessary for completing their job functions. By applying this principle, organizations can significantly minimize the risk of accidental or malicious misuse of sensitive information and systems.

Implementing the Principle of Least Privilege involves granting users the lowest level of access needed to perform their specific roles. For example, an employee who only needs to read documents should not have permission to delete them. This not only protects the integrity and confidentiality of data but also helps to contain potential breaches, as attackers who gain access to an account will have limited capabilities.

Other options mentioned do not encapsulate this principle. The Right to Access generally refers to the entitlement of users to access certain data or systems, but it does not imply any restrictions on the extent of that access. An Access Control Policy is a broader framework that outlines how access rights are assigned and managed but does not specifically define the least privilege concept. Data Encryption Standard pertains to methods for securing data and does not relate directly to user access levels. Thus, the Principle of Least Privilege is the correct and most applicable choice in this context
