DoS Protection Option/Protection Tab

Select the
Option/Protection
tab to configure options for the DoS Protection policy rule, such as the type of service (http or https) to which the rule applies, the action to take against packets that match the rule, and whether or not to trigger a log forward for matched traffic. You can define a schedule for when the rule is active.
You can also select an aggregate DoS Protection profile and/or a classified DoS Protection profile, which determine the threshold rates that, when exceeded, cause the firewall to take protective actions, such as trigger an alarm, activate an action such as Random Early Drop, and drop packets that exceed the maximum threshold rate.
Field
Description
Service
Click
Add
and select one or more services to which the DoS Protection policy applies. The default is
Any
service.
Action
Select the action that the firewall performs on packets that match the DoS Protection policy rule:
  • Deny
    —Drop all packets that match the rule.
  • Allow
    —Permit all packets that match the rule.
  • Protect
    —Enforce protections (on packets that match the rule) specified in the DoS Protection profile applied to this rule. Packets that match the rule are counted toward the threshold rates in the DoS Protection profile, which in turn trigger an alarm, activate another action, and trigger packet drops when the maximum rate is exceeded.
Schedule
Specify the schedule when the DoS Protection policy rule is in effect. The default setting of
None
indicates no schedule; the policy is always in effect.
Alternatively, select a schedule or create a new schedule to control when the DoS Protection policy rule is in effect. Enter a
Name
for the schedule. Select
Shared
to share this schedule with every virtual system on a multiple virtual system firewall. Select a
Recurrence
of
Daily
,
Weekly
, or
Non-recurring
. Add a
Start Time
and
End Time
in hours:minutes, based on a 24-hour clock.
Log Forwarding
If you want to trigger forwarding of threat log entries for matched traffic to an external service, such as to a syslog server or Panorama, select a Log Forwarding profile or click
Profile
to create a new one.
Only traffic that matches an action in the rule will be logged and forwarded.
Aggregate
Select an Aggregate DoS Protection profile that specifies the threshold rates at which the incoming connections per second trigger an alarm, activate an action, and exceed a maximum rate. All incoming connections (the aggregate) count toward the thresholds specified in an Aggregate DoS Protection profile.
An Aggregate profile setting of
None
means there are no threshold settings in place for the aggregate traffic. See Objects > Security Profiles > DoS Protection.
Classified
Select this option and specify the following:
  • Profile
    —Select a Classified DoS Protection profile to apply to this rule.
  • Address
    —Select whether incoming connections count toward the thresholds in the profile if they match the
    source-ip-only
    ,
    destination-ip-only
    , or
    src-dest-ip-both
    .
If you specify a Classified DoS Protection profile, only the incoming connections that match a source IP address, destination IP address, or source and destination IP address pair count toward the thresholds specified in the profile. For example, you can specify a Classified DoS Protection profile with a
Max Rate
of 100 cps, and specify an
Address
setting of
source-ip-only
in the rule. The result would be a limit of 100 connections per second for that particular source IP address.
