What are the core actions of the protect (PR) function in cybersecurity?

The protect function in cybersecurity is primarily focused on implementing safeguards to ensure the confidentiality, integrity, and availability of information. Controlling access to systems is a fundamental aspect of this function because it involves defining who has permission to view or use resources within an organization. This control is critical in preventing unauthorized access, which can lead to data breaches, theft, or other cyber incidents.

Access control measures can include the use of authentication methods (such as passwords or biometric scans), role-based access controls to assign permissions based on user roles, and other policies that limit how information systems can be accessed and by whom. By effectively controlling access, organizations can mitigate risks and protect sensitive data from threats, aligning with the broader objectives of the protect function.

This action emphasizes the importance of establishing a secure environment through appropriate access rights, which is essential for maintaining the overall cybersecurity posture of an organization.
