Assign source priorities in Exposure Analytics

Prioritize sources based on timeliness, accuracy, and completeness in Exposure Analytics. When Exposure Analytics aggregates sources, there might be conflicts between field values. With prioritization, you can decide which sources, and which particular fields, are the most accurate.

Exposure Analytics data processing stores high priority field values over low priority field values regardless of the consecutive order of the sources in which the fields came from. For example, two sources might provide different values for the same field. Exposure Analytics keeps only one value for each field: the one with the highest priority. A field value can only be overwritten by a field value with an equal or higher priority.

You can also set a retention period for field values so that the priority reduces or clears after a specific time period. Setting a retention period is useful for aging out a stale field such as an IP address. See Modify the retention period for asset inventory fields.

You can prioritize sources at the source level and at the field level. When you prioritize a source at the source level, Exposure Analytics assigns each field value from that source the same priority. You can be more granular by prioritizing a source at the field level, which allows you to assign different priorities to each individual field from a source. For example, a source might have a priority level of High, but the IP address from that source can have an individual field level priority of Highest.
