Reads the export, not the device
ConfigProof reads a configuration export. This control is evaluated against the objects in that file, and it reports what the file says. It does not connect to the device and sees no traffic, so a finding here describes the configuration, not what the firewall is doing right now.
Why it matters
SNMP v1 and v2c send the community in clear text, so anyone on the path can read it and query the appliance.
How to fix it
Web interface
The steps below are written for the web interface. A finding raised on your own export carries the same steps with your object names filled in.
- Disable the community under config system snmp community, and use an SNMP v3 user under config system snmp user.
Command line
FortiOS CLI
config system snmp communityedit <community-id>set status disablenextend
An example. Values in angle brackets are yours to supply; a finding on your own export fills in the names it read. FortiOS saves a change when you type next or end, with no separate commit. Read every line first.
Read it back
show system snmp communityValues to fill in1
- <community-id>
- The number of the SNMP community entry under config system snmp community
How to confirm the fix
- Run show system snmp community and confirm no community has status enable.
Limits
- No limitation is recorded for this control beyond the one that applies to all of them: it reads a configuration export.
Compliance references
No benchmark recommendation is mapped to this control in this version.
