Yes but I don't believe there is really much point. Even a weak intruder can gain physical access to a house so besides making you aware of it somewhat home security comes in only two forms: 1) Hoping nobody will intrude, and 2) Remote monitored security system.
My parents, for instance, have a deadbolt on their front door. Well by mistake I've already kicked the door in to the house before because the frame is just wood. Plus anybody can break into a window. If you want security you need an alarm system (and no guns do not work when you're not home and I'd rather have a screeching sound + cop cars coming as opposed to a gun fight around my family at 3:00 am).
