Fortinet 583 FortiWeb 5.0 Patch 6 Administration Guide
4. Configure these settings:
Setting name Description
Community
Name
Type the name of the SNMP community to which the FortiWeb
appliance and at least one SNMP manager belongs, such as public.
The FortiWeb appliance will not respond to SNMP managers whose
query packets do not contain a matching community name. Similarly,
trap packets from the FortiWeb appliance will include community name,
and an SNMP manager may not accept the trap if its community name
does not match.
Caution: Fortinet strongly recommends that you do not add FortiWeb
to the community named public. This popular default name is
well-known, and attackers that gain access to your network will often
try this name first.
