|
Choose the action FortiWeb takes when definite attack is
verified. alert—Accepts the connection and generates an alert
email and/or log message.
alert_deny—Blocks the request (or resets the
connection) and generates an alert and/or log message.
block-period—Blocks the request for a certain period of
time. |
alert_deny
|
action-page-method {alert | alert_deny | block-period}
|
Choose the action FortiWeb takes when HTTP method violation is
verified. alert—Accepts the connection and generates an alert
email and/or log message.

connection) and generates an alert and/or log message.
block-period—Blocks the request for a certain period of
time. |

Enter the number of seconds that you want to block
the requests. The valid range is 1–3,600 seconds. This option only takes effect when you choose Period
Block in Action. |

severity level will be displayed in the alert email and/or
log message. |
High
|
trigger-definitely "<policy_name>"
|
Select a trigger policy that you have set in
Log&Report > Log Policy > Trigger Policy. If
definite anomaly is detected, it will trigger the system to send
email and/or log messages according to the trigger
policy. |
No default. |

This option appears when you enable Dynamically
update when parameters change. Low—The system triggers model update only when the
entire data distribution area (from the maximum value to
the minimum value, that is, the entire area containing all
the data) of the new boxplot doesn't have any
overlapping part with that of the sample boxplots.
Medium—The system triggers model update if the notch
area (the median rectangular area in the boxplot where
most of the data is located) of the new boxplot doesn't
have any overlapping part with the entire data
distribution areas of the sample boxplots.
High—The system triggers model update as long as the
notch area of the new boxplot doesn't have any
overlapping part with that of the sample boxplots.
