Silva's 15 Common Weaknesses In Home Security

From security consultant Michael Silva, a very thorough review of 15 Common Weaknesses in Home Security.

Lots of interesting points made. I'll just cite the first sentence of the first one:

"Builders typically use inexpensive lock hardware when they build a home, sometimes even at homes costing millions of dollars."

I've noticed this as well. Seems strange.

Oh and Silva has no mention of cameras which may imply they have no weaknesses or they really have no role in actually securing homes :)


It is a good list. I have some I'd add too based on my experience:

#16: The family dog barks like crazy at random blowing leaves and the postman, but apparently loves any intruder or strangers if they give belly rubs.

#17: Exterior lighting is not used/ or in disrepair.

#18: Homeowners misuse social media to totally blab about when they are NOT home (vacations, nights out, soccer practice, etc)

Nice tip on DIY security bolts:

Drive a long screw into the edge of the door on the hinge side, cut off screw head, leaving approximately 1/2"of screw shaft exposed. Drill corresponding hole in the door frame so that when door is closed, screw enters hole in door frame

Funny thing is that because of some Macho aversion to pre-drilling I ended up inadvertently making several of these rookie blunders "security studs" in my own door; and have been suffering the sarcastic barbs of pretty much every contractor coming thru the door since. Now thanks to Mike, I can hold my head high...

Oh and Silva has no mention of cameras which may imply they have no weaknesses or they really have no role in actually securing homes :)

Take a look at this study; it was done back in 2012 so you may or may not have seen it yet. It's a pretty fascinating read, dispelled a few myths I have believed in my whole life.

Take a look at this study; it was done back in 2012 so you may or may not have seen it yet.

It was actually an IPVM Post-of-the-Month Club - Alternate Suggestion, for June 2014: Study Of Why Burglars Steal And What Impacts Them

One common myth NOT addressed by the study:

Convicted burglars will find it hard to acheive gainful employment in the security field.

This was of course famously dispelled by:

Burglars Are Standing By Waiting To Answer Your Questions...

You know what....I think this is where I saw that study...I guess my comment should be marked "unhelpful" lol

Similar to this topic, you often hear a recommendation to have your lights on randomized timers when you're away. While I don't think that is bad advice, it always seemed unnecessary to me. If someone is staking out your house and noting the exact time the lights come on, they'll probably also notice the lack of anyone coming or going.

Our lights have been automated for the last 20 years, key lights come on at dusk, and go off at set times if we're home or away. I've never felt like this predictability of lighting schedules made us a target.

From that study, I linked to above. It showed most burglaries were spur of the moment, I believe. So set schedules would theoretically work just fine.

Mike Silva always gives quality advice. One of the best consultants in the business.
