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
Every site reaches every other site on every port, so a compromise at one site spreads across the whole VPN.
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.
- In the Meraki Dashboard: Security & SD-WAN > Site-to-site VPN > Organization-wide settings > Site-to-site outbound firewall: replace the rule with rules for the traffic sites need.
Command line
This analyzer version writes no command text for this control. The steps above are the remediation it offers.
How to confirm the fix
- In the Meraki Dashboard: the site-to-site outbound firewall shows no rule allowing any to any above the default.
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.
