If two or more sources have the same rank, then the last nonempty value is the priority. Source A is the higher rank, therefore takes higher precedence when merging single valued fields. These merge on the matching key identity fields, and the priority is set to low. For example, if you have identity lists called source A and source B: You can rank the order of your asset and identity lists to determine priority for merging assets and identities. See Correlation Setup for enabling correlation and making lookups automatic. ![]() The priority field in an automatic lookup table affects notable event urgency. When a correlation search runs, the results are enriched with the data from these automatic lookups. When asset and identity correlation is enabled, if you have made your lookups automatic, the Asset and Identity Framework helps to calculate the event urgency. Modify priority and rank in the Asset and Identity Framework Modify notable event severity in correlation search syntax.Modify priority and rank in the Asset and Identity Framework.Use one of the following methods to modify the urgency assigned to notable events: You may also modify the urgency level once the notable is created and this modified value for urgency is then used by the incident review lookup. This ensures that all notable events are displayed in Incident Review. Incident Review filters on the urgencies of "high", "medium", "low", "critical", "informational", or "unknown." Any value that is not one of the filtered urgencies also defaults to "unknown". If asset priority is critical and event severity is high or critical, the event urgency is critical.Ī notable event can be assigned an "unknown" urgency level if the priority value from the asset and identity lookups or the severity value assigned by the correlation search or in a triggering event is not recognized by Enterprise Security.If asset priority is critical and event severity is medium, the event urgency is high.If asset priority is critical and event severity is unknown or low, the event urgency is medium.If asset priority is high and event severity is unknown, low, or medium, the event urgency is medium.If asset priority is medium and event severity is critical, the event urgency is critical.If asset priority is medium and event severity is high, the event urgency is high.If asset priority is medium and event severity is medium, the event urgency is medium.If asset priority is medium and event severity is unknown or low, the event urgency is low.If asset priority is unknown or low and event severity is critical, the event urgency is high. ![]() ![]() If asset priority is unknown or low and event severity is high, the event urgency is medium.If asset priority is unknown or low and event severity is unknown, low, or medium, the event urgency is low.If event severity is informational, the event urgency is informational, regardless of asset priority.The default results can be overwritten by modifying priority and rank, search syntax, or urgency lookups. This table provides an example of how the urgency values are calculated in notable events by default. You may use the Urgency field to prioritize the investigation of notable events. If both the asset and identity in the notable event have an assigned priority, the higher priority is used to calculate the urgency. The severity value is set directly on the notable that is generated by the correlation search. The following fields are used to determine priority when priority is assigned through an asset and identity lookup: The urgency_lookup determines the urgency level by using both the severity and priority value assigned to the notable that is generated from the correlation search and the priority assigned to specific fields in the assets and identities.
