During which phase do authentication errors occur in the Discovery process?

Authentication errors in the Discovery process typically occur during the classification phase. In this phase, the system attempts to identify and classify the discovered services and applications based on the information gathered so far. If the system encounters issues with authentication—such as incorrect credentials or access rights—these problems will prevent it from accurately identifying or classifying the configuration items (CIs) and services.

During the identification phase, the focus is largely on discovering devices and their basic characteristics, which is less prone to authentication errors since it primarily involves recognizing systems on the network. The exploration phase deals with deeper inquiry into the discovered items to understand their dependencies and configurations but does so under the assumption that initial authentication has been successfully established.

Additionally, during the port scan phase, the focus is on identifying open ports and services on those ports, so this aspect does not typically involve authentication challenges as it revolves around network-level engagement rather than accessing application-level information. Thus, the correct association of authentication errors with the classification phase aligns with the functional responsibilities of that step in the Discovery process.
