DESCRIPTION
Select either Attack, Intrusion, Antivirus or Antispam in this
field.
Set your filters according to how many attacks, intrusions, virus
and spam are detected on a device. The following parameters can
be used.
• >= - Select this if you want to be alerted when number of
encounters is greater than or equal to the value you set.
• <= - Select this if you want to be alerted when number of
encounters is less than or equal to the value you set.
• < - Select this if you want to be alerted when number of
encounters is greater than the value you set.
• > - Select this if you want to be alerted when number of
encounters is less than the value you set.
For example, choose Attack, select >= and set the percentage
value to 5. This means Vantage Report sends an alert once a
monitored device receives 5 attacks for a set time (see Period..
minutes field below).
Set this to the number of minutes the condition persists before
Vantage Report sends out an alert.
Using the previous example, you can set the period to 5 minutes.
This means that if the device received 5 attacks within 5 minutes,
Vantage Report sends out an alert.
