See, I think the main problem behind this can be like most of the times people used to forget about the main things such a strong doors, door bolts. Also making sure all windows and doors are locked during the day when you are home. Plus to think about some place or an emergancy place from where you can call the police if you are in trouble. And lastly the most important time i.e in the night time you can add outdoor security cameras. I hope my suggestion would help you all at least a bit.
