Click **Detections \\\u003e Rules \\& Detections** \\\u003e the **Rules Editor** tab.\n\n2. Use the **Search rules** field to search for an existing rule. You can also scroll through the rules using the scroll bar. Click any of the rules in the left panel to view the rule in the rule display panel.\n\n3. Select the rule you are interested in from the Rules List. The rule is displayed in the rule editing window. By selecting a rule, you open the rule menu and can select from the following options:\n\n - **Live Rule**---Enable or disable the rule.\n - **Duplicate Rule**---Make a copy of the rule; helpful if you want to make a similar rule.\n - **View Rule Detections**---Open the Rule Detections window to display the detections captured by this rule.\n4. Use the Rule Editing window to edit existing rules and to create new rules.\n The Rule Editing window includes an automatic completion feature to enable you\n to view the correct YARA-L syntax available for each section of the rule.\n Whenever composing or editing a rule, Google Security Operations recommends walking\n through the automatic recommendations to ensure your completed rule uses the\n correct syntax. To update the rule scope, select the scope from the\n **Bind to scope** menu. For more information about associating a scope\n with a rule, see [data RBAC impact on Rules](/chronicle/docs/administration/datarbac-impact#rules).\n For more information, see [YARA-L 2.0 language syntax](/chronicle/docs/detection/yara-l-2-0-syntax).\n\n5. Click **New** in the Rules Editor to open the Rules Editor Window. It\n automatically populates it with the default rule template.\n Google SecOps automatically generates a unique name for\n the rule. Create your new rule in YARA-L. To add a scope to the rule, select the\n scope from the **Bind to scope** menu. For more information about adding a scope\n to rules, see [data RBAC impact on Rules](/chronicle/docs/administration/datarbac-impact#rules).\n When you have finished, click **SAVE NEW RULE** . Google SecOps checks the\n syntax of your rule. If the rule is valid, it is saved and automatically enabled.\n If the syntax is invalid, it returns an error. To delete the new rule, click **DISCARD**.\n\n | **Note:** After you have saved a rule, you cannot delete it from the Rules Editor or the Rules Dashboard.\n | **Note:** For Multi-event rules correlating more than one event with a match section size of over one hour, the rule's run frequency (when executing as a Live Rule) is automatically set to 1 hour.\n6. To view information on the current detections associated with a rule, click\n the rule in the rules list and click **View Rule Detections** to open Rule\n Detections view.\n\n The **Rule Detections** view displays the metadata attached to the rule and\n a graph showing the number of detections found by the rule over recent days.\n7. Click **Edit Rule** to return to the Rules Editor.\n\n #### Multicolumn view\n\n The **Timeline** tab is also available and lists the events detected by the rule.\n As with the **Timeline** tab in other Google SecOps views, you can\n select an event and open the associated raw log or UDM event.\n\nClick view_column **Columns**\nto open the multicolumn view options and\nchange the information shown on the **Timeline** tab. The multicolumn view lets\nyou choose from various categories of log information, including common types,\nsuch as `hostname` and `user` and more specific categories provided by UDM.\n\n1. Click **RUN TEST** to test your rule. Google SecOps runs the rule on events in the specified time range, generates results, and displays them in the **TEST RULE RESULTS** window. \n Click **CANCEL TEST** at any time to stop the process.\n\n| **Note:** Successive executions of the same test rule may generate different test detections and is expected behavior. Google SecOps runs a test rule in multiple parallel processes and detections are streamed to the dashboard as each process finishes. Minor timing differences can affect which duplicate detections are removed. By extension, results may not match those of live rules or retrohunts.\n| **Note:** Test rule detections aren't persisted and don't generate alerts. This behavior allows rule authors to iterate without affecting production. Test rule detections may differ from retrohunt or live rule detections because the evaluation windows may be aligned differently.\n| **Note:** These test results are not saved and won't be viewable in the Rules Dashboard.\n\nFor Community blogs on managing rules, see:\n\n- [Rules Editor Navigation](https://www.googlecloudcommunity.com/gc/Google-Security-Operations-Best/Getting-to-Know-Google-SecOps-SIEM-Rules-Editor-Navigation/ta-p/659309)\n\n**Need more help?** [Get answers from Community members and Google SecOps professionals.](https://security.googlecloudcommunity.com/google-security-operations-2)"]]
