That's the gist of it if your concern is random break-ins. Make your property the least "attractive" in the neighborhood to criminals. Establish a clear perimeter, install motion sensor lights and cameras, post an alarm company sign, put a big dog igloo where the back or side can be easily spotted from the alley and street, don't park expensive cars out where they can be seen from the street or alley.
Then add natural barriers along the edge of the perimeter like thorny bushes thickly planted, clear hiding places away from the walls and windows of the house (or plant those in blood drawing flowering plants with large thorns), harden doors and windows against forced entry by replacing deadbolts with higher security versions, upgrade striker plates, and replace frame and hardware screws with long screws that go all the way into the 2x4 framing. If the doors themselves are weak, replace them with solid wood, fiberglass, or steel. The objective is to make it clearly difficult to enter the property and the house.
