Which information can you see by expanding an entry in the Unified Audit?

Expanding an entry in the Unified Audit provides detailed insights into the file and application involved in the event. This includes the complete file path, which helps in identifying precisely which file was accessed or modified. Additionally, knowing the application that interacted with the file provides context about the source of the action. The base64 encoding of the file can be important for various purposes, such as ensuring the integrity and security of the file's content as it allows for the representation of binary data in an ASCII string format, which can be useful for data transmission or storage.

These details are crucial for thorough auditing and investigative processes, allowing security teams to track specific actions and determine potential issues or breaches within the system. Understanding the exact application and file context helps in formulating a response to security incidents and in troubleshooting.

Other choices, while they may provide useful information, do not encompass the comprehensive detail provided by option B. For instance, file size and date modified give limited context about the security implications of a file access event, while understanding ownership and permissions is more relevant for managing access control rather than auditing individual events. Lastly, last accessed time and user interactions, although useful, do not provide the same level of specificity regarding the file and application involved.
