Suppressing specific AWS and host behavior anomaly alerts reduces the number of alerts and allows you to focus on the assets that are most important to you.
To use policies to suppress specific behavior anomaly alerts, follow these steps:
- Navigate to Monitor > Policies.
- Behavior anomaly suppression rules are available for AWS and host policy types.
In the Behavior Anomaly Suppression Rules table, locate the event you want to suppress and expand it.
- Click Clone.
- Enter a name for the event.
- Use the available columns to define the conditions for suppressing this event.
You must select EXCLUDE to suppress the event for the specified conditions.
Example: For the New External Server IP Address event, you could add these conditions: IP ADDRESS EXCLUDE 10.0.10.1, 10.0.10.2 AND PORT EXCLUDE 80, 443. Below is a screenshot of an example.
This will exclude the event of type New External Server IP Address only when the IP address matches 10.0.10.1 or 10.0.10.2 and the port matches 80 or 443.
The table below provides examples for available conditions.
- Ensure the rule is enabled and click Save.
- Ensure the Lacework rule that you cloned remains enabled.
After you suppress an alert, Lacework does not generate an event for the conditions you specified.
If you disable the Lacework rules category from which a rule was cloned, that setting takes precedence, meaning the entire category of that event type is disabled.
You can also use the * wildcard when defining conditions.
|IP_ADDR||192.0.2.0 - Note that IP ranges are not supported. However, you can use the * wildcard to simplify some exceptions. For example, you can add 192.0.2.0 as 192.0.* if you have a common range.|
