It's not possible as far as I know. That data is simply there to tell you the firewall is doing its work.
VERY disappointing. The detailed data in the history is of very limited value if you can't extract it for analysis.
It would be one thing if there were only one or two entries. But I have to believe that in the typical situation where I need to react or take some action there are likely to be thousands of entries. In this case the current Security History screen is of almost no value.
I believe the way they look at it would be to say, "that's the whole point, there's no action to take".
The availability of those logs harks back to earlier versions of the software and there's talk of losing that part of the GUI.
The logs can be downloaded and read by support staff in a proprietary format if need be during a support session..
