Which source must be configured to access reputation information in Tanium?

The option that pertains to accessing reputation information in Tanium is Tanium Reputation. This functionality is specifically designed to assess the trustworthiness of files, URLs, and IP addresses based on a predefined database of known threats. By integrating reputation data, Tanium enables organizations to make informed decisions regarding potential security threats, improving their overall posture against malicious activities.

The other choices, while related to Tanium's capabilities, do not specifically handle reputation data. Tanium Discover focuses on identifying assets within an environment, Tanium Enforce is related to applying policies and controls to endpoints, and Tanium Comply centers around compliance assessments and reporting. While these tools enhance the security and management landscape, they do not serve the role of fetching and interpreting reputation-related intelligence.
