Authentication, authorization, and identification are distinct but essential elements of application security, especially in managing machine identities. Identification involves recognizing a device or system using identifiers such as IP addresses, MAC addresses, device names, or serial numbers in industrial settings. Authentication verifies that the claimed identity is valid, ensuring only legitimate devices or users can connect. Authorization then determines what actions or resources the authenticated entity is allowed to access. Together, these processes enable organizations to monitor, control, and secure devices across networks and systems, improving operational efficiency and reducing the risk of unauthorized access, misuse, or cyber threats.
