You can delete custom cloud security rules. For example, you may consider deleting a previously defined cloud security rule if it is generating too many false-positive issues.
To delete a custom cloud security rule:
Navigate to Posture Management → Rules & Policies → Rules → Cloud Security.
From the Rules page, there are two ways to access the option:
Right-click the entry and then select Delete.
Click on the policy. Next, on the Details page, click the more options icon (⋮) and then select Delete.
