What is essential for the External Storage Credentials functionality to work in ServiceNow?

For the External Storage Credentials functionality to work in ServiceNow, enabling the Discovery External Credential Storage plugin is crucial. This plugin is specifically designed to facilitate the secure storage and management of credentials that are necessary for accessing external systems during the discovery process. By enabling this plugin, you unlock the features that allow ServiceNow to utilize external credential storage, ensuring that sensitive information is handled appropriately and efficiently.

The functionality provided by the plugin enhances the overall security posture of the ServiceNow instance by enabling the use of external credentials without hardcoding them in scripts or configurations. This separation of credential management from the discovery process helps maintain security best practices and enables easier updates to credentials when needed.

In contrast, other choices do not contribute to the necessary operational framework for leveraging external storage for credentials. For instance, disabling the Mid Server or only using local storage solutions would undermine the ability to connect to external resources effectively, while having manual credential entries does not inherently enable the necessary security and management features that the plugin provides.
