4.1 Unified Write Filter
The "Unified Write Filter" (UWF) protects the system from persistent storage of malware and
viruses. When the UWF is enabled, the system hard drive is locked down and all system
changes are only cached. When rebooting the file system, the cache is deleted and the original
configuration is loaded again.
To store a configuration persistently, you must disable the UWF and reboot the system. After
you have implemented the configuration, enable the UWF and reboot again. This triggers the
persistent storage of the configuration.
Caution!
24/7 Operation
During 24/7 operation and enabled UWF, the system can run out of memory.
Note
User Access to UWF
Only users logged in as "Administrator" can enable and disable the UWF.
Note
3rd Party Software
When using 3rd party software (e.g. antivirus software), verify if the software is compatible to
the UWF and does not write large amounts of data onto the hard drive.
Note
Enabling and Disabling the UWF
The UWF can only be enabled and disabled in the administrator view. Log in as an PFAdmin
before performing following steps.
