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
A service presenting an expired certificate fails validation on any client that checks it. Where the certificate signs decrypted sessions, users can learn to click through the warning, which removes the signal that would otherwise expose an interception. Where it terminates a portal, clients that check it cannot connect.
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.
- Identify every profile, portal and gateway that references this certificate.
- Issue a replacement from the same authority and import it with the full chain.
- Update each reference to the new certificate, then remove the expired one.
Command line
PAN-OS CLI, standalone firewall, vsys1
set vsys vsys1 ssl-tls-service-profile <profile-name> certificate <new-certificate-name>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 vsys vsys1 certificate <object-name>Values to fill in3
- <object-name>
- The object's name, as it appears on your firewall
- <profile-name>
- Which profile to change. A firewall carries several of each kind.
- <new-certificate-name>
- The name of the certificate you imported
Before you type it1
- No command renews a certificate. Import the new file, then point the profile at it.
How to confirm the fix
- Confirm the replacement is presented by connecting to each service that uses it.
- Confirm no profile still references the expired certificate before deleting it.
Limits
- Whether the certificate is currently presented to any client is not visible in a configuration file.
- The assessment date, not the current date, is what the comparison uses, so a report stays reproducible.
Compliance references
