For me a gun is not a part of hiking / camping equipment, so it's kinda hard to say what I carry instead of it.
Maybe I've seen too many films but I believe some kind of ballistic apparatus should be a normal part of any outdoor equipment.

Well I for one think we over blow the "security in the woods" topic on this forum.
I don't think so. At least here in Germany we have a security problem in the outdoors, not a big one but also no bagatelle. During the 1990's there were many gangs of Romanian thieves camping in the woods, and during the last years some hunters were killed, probably by robbers and militant animal activists. Not to talk about minor problems as aggressive dogs and dogfights, drunken teenager hords or criminals storing their loot.
I have made two negative experiences myself. At the first I encountered a wood thief, at the second I was attacked by a dog whose owner rescued me just in the last seconds (I had my knife already in position).
These problems accure because there is no real wilderness here in Central Europe. Nearly all woods are part of the man-made 'cultural landscape' and are easy to reach with lots of roads and trails. (The only exceptions are the national parks - where BTW all forms of camping are strictly prohibited - and some mountain areas.) So it's not difficult for 'problematic people' to go to the woods and fields. I quite often meet ordinary people - dog walkers, riders, and nordic walkers - on my hikes, even at places I wouldn't expect it. And I always try to go to the more remote areas because I want to be alone or with my partner.
