Starting with PAN-OS 8.1.1, firewalls and
Panorama perform software integrity checks for tamper detection
and software corruption. The software integrity check validates
that the operating system and data file structure are intact and
as delivered by Palo Alto Networks. When the check is successful,
a System log of informational severity is generated. If the check
detects a software corruption or possible appliance tampering, it
generates a System log of critical severity on PAN-OS 8.1.1 and
8.1.2. Starting PAN-OS 8.1.3, the appliance goes in to maintenance
mode when the check fails. If you're using Panorama with GlobalProtect
Cloud Service or the Logging Service, you must install Cloud Services
plugin 1.0.3 before you upgrade Panorama to PAN-OS 8.1.1. If you
attempt to upgrade Panorama to 8.1.1 with an Cloud Services plugin
version earlier than 1.0.3, the Panorama upgrade will fail. |
