What is meant by the procedure of checking user rights for resource access at the physical connection level?

The procedure for verifying user rights at the physical connection level is an authentication and authorization process that occurs when establishing a physical connection to the system (for example, when connecting to a network or device). It includes checking whether the user or device has the right to connect to the system using mechanisms such as:

• Credential verification (login/password, certificates, tokens).
• Access control at the network equipment level (e.g., MAC filtering).
• Use of authentication protocols (e.g., 802.1X for networks).

Thus, this procedure ensures that only authorized users or devices can access system resources through a physical connection.
