Alert correlation rule form
Manage the fields that define how alerts are correlated and grouped.
| Field | Description |
|---|---|
| Name | Name of the correlation rule. |
| Order | The evaluation priority for the rule. Rules with lower numerical values are given higher priority. An alert is evaluated against each alert action rule until a match is
found. For example, if you have two alert correlation rules with priorities 10 and 20, respectively, the rule with priority 10 will be evaluated first. If an alert matches the criteria of the rule with priority 10, no further rules will be checked. If it doesn’t match, the alert will then be evaluated against the rule with priority 20. |
| Active | Option to activate or deactivate the rule. |
| Advanced | Option to switch to advanced mode, which lets you use custom scripts to define your own logic. The sample correlation rule, Alert correlation rule SAMPLE, is provided out-of-the-box for reference.
You can use the available script as a guide. 주:
The Filter condition specifies which alerts the rule will apply to. Ensure that the same condition is used in the advanced script to identify alerts to be included in the group. |
| Description | Description of the rule. |
| Primary Alert | The filter condition to identify the alert that is the primary alert, or most important alert, in a set of related alerts. This field does not appear when Advanced is selected. |
| Secondary Alert | The filter condition to identify the alert that is related to the primary alert, however it is of lesser importance. This field does not appear when Advanced is selected. |
| Filter | The filter condition to identify the alert on which the script is run. Filter is available only when Advanced is selected. Filter parameters are case sensitive by default. To disable case sensitivity, set the sa_analytics.correlation_case_sensitive parameter to false. |

This field does not appear when the Advanced check box is selected. |
| Time Difference in Minutes | The minutes between which the primary and secondary event must occur to match this rule. The default value is 60 minutes. 주:
