Alert Filters

Alert Filters allow you to automatically override the risk levels of any alerts raised by the active and passive scan.

There are 2 different types of Alert Filter:

• Context Alert Filters

• Global Alert Filters

Alert Filters can also be defined in the Automation Framework .

The easiest way to create Alert Filters is to right click an alert and select the ‘Create Alert Filter…’ option. This will display the Alert Filter Dialog .

You can also create Alert Filter manually. By default Alert Filters only apply to new alerts, but you can both test and apply the Alert Filters to existing alerts.
