**To view correlation rules**

1. Go to **Settings > Rules > Correlation Rules**.
2. You can use the search field above the table to search for a rule by entering the search text in the field and then clicking the <img src="https://mintcdn.com/levelblue-5324744e/CMgZi2NlC_uJcr6v/images/usm-anywhere/search-blue.svg?fit=max&auto=format&n=CMgZi2NlC_uJcr6v&q=85&s=d8f0e97fcad12e75cf65ca08be90ddd5" className="inline" width="20" height="20" data-path="images/usm-anywhere/search-blue.svg" /> icon. You can also filter the rules by **Rule Type** (Customized - rules overriden by users or LevelBlue - rules provided by LevelBlue Labs Threat Intelligence) or **Rule Status** (Enabled or Disabled).
3. Click the rule to expand and see the rule details. You can see the strategy, method, and rule itself. You will also see the number of occurrences, length, mute length, and priority assigned to the correlation rule. You can edit the default values. See instructions below for overriding correlation rules.

   <Warning>
     **Important:** Correlation rule details are not visible to users with a trial license.

   The page includes Rules Name as a filter so that you can see how many alarms match the selected rule.
