• Content 'Device Security' info is also known as the Device Dictionary and it's an XML file for Palo Alto Firewalls to use in Security policy rules based on Device-ID.
• It contains entries for various device attributes and is completely refreshed on a regular basis and posted as a new file on the update server.
• If there are any changes to a dictionary entry, a revised file will be posted on the update server so that Panorama and Firewalls automatically download and install it the next time they check the update server.
• The update happens automatically every two hours. 
• The following medium severity error message could be sometimes printed to the system log.

• Panorama
• Palo Alto Next Generation Firewalls
• Supported PAN-OS versions

The medium severity error message in the title indicates that Panorama or PA-Series Next-Generation Firewalls faced an error during the Device Dictionary update process.

1. If the same error does not persist on the subsequent update process, you can safely ignore it as a temporal issue between Panorama/PA-Series Next-Generation Firewalls and the update server (no actions are required).
2. If the same error persists on several subsequent update processes, contact Palo Alto Networks support for further assistance.
