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
Without a permitted IP list, anything that reaches the management interface may poll SNMP. SNMP returns interfaces, routes and neighbors, which maps the network for whoever asks, and with v2c the community string is the only barrier.
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.
- Add the monitoring servers' networks to the management interface's permitted IP list.
- If SNMP polling is not used, turn the SNMP service off on the management interface.
- Move polling to SNMP v3 where the monitoring platform supports it.
Command line
PAN-OS CLI
set deviceconfig system permitted-ip <management-network>An example. Values in angle brackets are yours to supply; a finding on your own export fills in the names it read. Nothing here commits. Review the candidate configuration, then commit it yourself.
Read it back
show deviceconfig system permitted-ipValues to fill in1
- <management-network>
- The network your administrators connect from
Before you type it1
- A permitted address list that leaves out your own network locks you out.
How to confirm the fix
- Confirm the permitted IP list names only the management networks.
- Confirm the monitoring platform still polls the device after the change.
Limits
- No limitation is recorded for this control beyond the one that applies to all of them: it reads a configuration export.
