# Suppression Rules from the Orchestration Rules Page
Role Availability | ❌ Read-Only ✔️ Analyst ✔️ Manager
## About Suppression Rules
USM Central includes suppression rules that enable you to manage false positives alarms. After you have confirmed that these issues do not pose a security threat, create a suppression rule to prevent these issues from displaying in the user interface (UI), and avoid noise in your system.
You can create a suppression rule from the details page of an alarm [(View Alarm Details](/usm-central/alarms/view-alarms-details)). This functionality works the same way, and the Create Rule dialog box is similar when you are creating a rule either from a detail page or from the system configuration window. Although it is not a rule, you can also suppress a specific alarm.
The easiest way to configure a suppression rule is from the Alarms details page (see [Creating Suppression Rules from the Alarms Page](/usm-central/alarms/suppression-rule) for more information).
The suppression rule you create applies to future items. It also applies to items of the current day, up to 10 K alarms.
## Managing Suppression Rules
To create a suppression rule from the orchestration rules page
1. Go to **Settings > Rules**.
2. Select **Create Orchestration Rule > Create Suppression Rule**.
3. Enter a name for the rule.
4. Select a deployment.
5. Select the property values you want to include in the rule to create a matching condition.
6. Click **Add Condition** and select the property values you want to include in the rule to create a matching condition.
If the field is related to the name of a country, you should use the country code defined by the [ISO 3166](https://www.iso.org/iso-3166-country-codes.html).
The Sources or Destinations field needs to match the universally unique identifier (UUID) of the event or alarm. You can use the Source Name or Destination Name field instead.
7. (Optional.) Click **Add Group** to group your conditions.
See [Operators in the Orchestration Rules](/usm-anywhere/user-guide/rules-management/orchestration-rules-operators) for more information.
8. In the **Occurrences** text box, enter the number of event occurrences that you want to produce a match on the conditional expression to trigger the rule.
You can enter the number of occurrences or use the arrows to scroll the value up or down. You can enter a number between 1 and 100.
9. (Optional.) Click the **More** link to include a multiple occurrence parameter.
10. In the **Length** text box, specify the timespan that you want to use to identify a match for multiple occurrences. Enter the number in the text box, and then use the drop-down menu to select a value of seconds, minutes, or hours.
This duration identifies the amount of time that transpires from the beginning to the end of the occurrence. If the number of occurrences is not met within this period, the rule is not a match.
Your defined length and occurrences function together to specify the number of occurrences within a time period that will produce a match for the rule. For example, you can define a rule to trigger an alarm for an unauthorized access attempt when a failed SSH login occurs three times within a five-minute window.
11. Click **Save Rule**.
The created rule displays in the list of rules.
It takes a few minutes for an orchestration rule to become active.
