Adjusting minimum thresholds by percentage
You can arbitrarily adjust SPP thresholds by percentage. This is useful when you expect a spike in legitimate traffic (for example, because of a news story or an advertising campaign). You can adjust the thresholds by as much as 300%.
Before you begin:
• Go to Protection Profiles > Thresholds > Thresholds and note the settings so that you can later verify the adjustment procedure or subsequently reset the thresholds to the values before the adjustment procedure.
• You must have Read-Write permission for Protection Profile settings.
To adjust minimum thresholds by percentage:
1. Go to Protection Profiles > Thresholds > Percent Adjust.
2. Select the SPP of interest from the drop-down list.
3. Specify a percentage in the text box. For example, to increase the threshold by 20 percent, enter 20. To decrease it by 20 percent, enter -20.
4. Save the configuration.
5. Go to Protection Profiles > Thresholds > Thresholds and verify that the adjustment has been applied.
