For this example, select Numeric Range Match in the Comparison Type drop-down menu.
Select http from the Protocol list.
Because you selected HTTP, the Custom Attack Editor displays the http specific protocol fields on the screen.
Configure the fields for the comparison you have chosen.
For this example, specify dst-port for the Protocol Field. This specifies that the Sensor should search in the URI of the request packet.
From the drop-down list in the Operator, select the matching criteria as Equals which means that the comparison criteria must be between to the minimum and maximum values entered.
Type the minimum value in the Mininum Value field.
For this example, the minimum value is "100".
Type the maximum value in the Maximum Value field.
For this example, the value to match is "2000".
