Some ideas, just remember when traveling overseas for women, your best defense is proximity alarms, lots of loud noise and some type of wedge since firearms and knives aren't options overseas, but big kitchen knives and things you can use as a club while loud noise is being blasted helps. Bottom line is never ever be taking alive. In the states firearms are recommended with prox alarms.

Proximity alarm so you know who's getting ready to try to get in

And my personal favorite that I highly recommend is a Model 500ES snub nose .50 bear pistol,you can use it to kill bears and shoot through walls and doors that try to come in. I guarantee one shot from this thing and they will think twice about coming in.
