Sometimes you may want to see when policy was last installed and by who, this information is kept for a short while in the Event Log on the appliance. Once the Event Log rolls over however this data will no longer be available.
The ProxySG does not log what changes where made, only that they were made, as this is the case it is always good practice to backup your policy before making changes. For information on how to backup the VPM policy please see How to export and import the Visual Policy Manager (VPM)
In the Event Log search for the following:
"Config admin at 188.8.131.52 'username', installed new VPM Policy File and VPM XML File"
"Config admin at 184.108.40.206'username', installed new Local Policy File"
"Config admin at 220.127.116.11 'username', installed new Forward Policy File"
"Config admin at 18.104.22.168 'username', installed new new Central Policy File"
