What does the term 'access control' refer to in network security?

The term 'access control' in network security specifically refers to the management of who has permission to use various resources within a network. This includes defining user identities, assigning role-based access privileges, and implementing security measures to protect system integrity and availability. By ensuring that only authorized individuals can access certain data or systems, organizations can safeguard sensitive information and reduce the risk of unauthorized access, breaches, and other security incidents.

The importance of access control lies in its foundational role in establishing network security policies and compliance with regulations, thereby ensuring that sensitive information is protected from internal and external threats.
