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
The only tunnel into this zone is disabled. Re-enable it and the rule is live again as it was written, without the review a new rule would get, including a rule that allows any to any.
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.
- If the tunnel is retired, disable or delete this rule and the others that name its zone, then the zone and the tunnel.
- If the tunnel is coming back, review the rule before it does, as if it were new.
Command line
PAN-OS CLI, standalone firewall, vsys1
set vsys vsys1 rulebase security rules <object-name> disabled yesAn 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 vsys vsys1 rulebase security rules <object-name>Values to fill in1
- <object-name>
- The object's name, as it appears on your firewall
Before you type it1
- Disable the rule only if the tunnel is retired. If the tunnel is coming back, review the rule instead.
How to confirm the fix
- Confirm no enabled rule names the zone.
- Confirm the tunnel, its gateway and the zone are removed or intentionally kept.
Limits
- Reported only when every source zone or every destination zone of the rule is fed by disabled tunnels alone, and only when every definition of the zone is.
