Hotel Room Security Tip

I haven’t written about physical security in some time, but recently I was in a hotel in San Francisco and experienced a very small physical security issue. This is an issue that you have probably confronted at some point, unawares. Fortunately, it is easily correctable if you follow my one simple hotel room security tip: Continue reading “Hotel Room Security Tip”

How to Choose a Locksmith

You stopped on the way home to grab a gallon of milk. You get to the car and pull the handle but the door remains stubbornly closed. You fish in your pocket for keys while your mind is still processing the fact that they’re sitting on the driver’s seat. You’d call your wife but she’s still at work all the way across town. Grudingly you pull out your phone and search “locksmith near me”.  This probably isn’t you, but this is how a lot of people choose a locksmith.

Blink: Get Notified When Your Mac Wakes

Chances are good that most – if not all – of us leave our computers unattended somewhere, sometime. For me this is at home. Though I generally abide by best practices and shut down before leaving my computer, occasionally I don’t. I can be caught close my MacBook’s lid and heading out the door to run an errand, walk the dog, whatever. I do have some peace of mind that no one is messing with my computer, however. This is because of an app called Blink.

Vehicle Privacy and Security

After hearing my recent interview with Aaron on the In the Rabbit Hole Urban Survival Podcast a couple weeks ago, I realized that I’ve yet to talk about vehicle privacy and security. For those of us in North America, vehicles are a way of life. Vehicles present some unique privacy and security challenges. In this post I’m going to talk about a few things you can do to improve vehicle privacy and security. Most requires some minor behavioral modification.

ITRH Interview on Physical Security

Quick announcement: I was recently interviewed for the In the Rabbit Hole Urban Survival Podcast. This time Aaron and I talked about physical security. We had time to delve pretty deeply into some good topics including general security considerations, deadbolts, padlocks, and safes (a lot of stuff about safes). If you’re interested check it out at If you like it, feel free to let Aaron know. Continue reading “ITRH Interview on Physical Security”

Enhancing Deadbolt Security

In my last post I recommended some specific locks. This week’s post will cover improving the security of existing locks, or the Grade 1 hardware I recommended. The goal is to create a “Grade 1+” lock, by adding some additional security measures. Enhancing deadbolt security very achievable with just a little spare time, access to a locksmith, and some basic hand tools. Continue reading “Enhancing Deadbolt Security”

Threat Model-Based Deadbolt Selection

Several weeks I ago I wrote a post about Mechnical Lock Threat Models, detailing categories of locks, and the users who should have them. In this post I am looking specifically at deadbolt selection, and offering some recommendations based on my mechanical lock threat models. Continue reading “Threat Model-Based Deadbolt Selection”

Lock Safari NYC – New York, New York!

I recently had the chance to spend a few days in New York, New York.  This was a personal trip, and I covered a lot of ground. This time, I actually managed to focus on the locks I saw, and I saw some good ones on Lock Safari NYC. I noticed some interesting things about New York’s locks. First, there are a LOT of high-security locks on the street. In Manhattan (LES, SoHo, Midtown, Theatre District) and Brooklyn (including DUMBO and Red Hook), where I spent most of my time, the numbers of high-security and “standard” locks seem almost equal. I also noticed, as expected, a ton of Medeco locks. What surprised me was the huge number of Mul-T-Locks. They probably rivaled the number of Medecos I witnessed.  Finally, I did not see the diversity of locks I had hoped to.  New Yorkers seem to buy a lot of Medecos or Mul-T-Locks, and little else.  With that said, let’s look at some hardware!

Hotel Room Insecurity

I travel a lot, and I stay in a lot of hotels. For the last five years I have averaged somewhere 150-200 nights a year in hotels.  This year (so far) has seen me in hotels in at least 32 different cities including Boston, Charleston, Knoxville, Las Vegas, New York, Phoenix, Salt Lake City, San Diego, Tampa, Vancouver, and a host of military towns.  This gives me a lot of opportunities to see and think about the security of hotels and hotel rooms.  Hotels generally try to put on a face of security with signs reading, “For our guests’ safety this door is locked between the hours of __ and __”.  I have found this, in reality, to be so much security theater.  Hotel staff are trained in hospitality, not security.  And no matter how secure a hotel attempts to be, there are inherent flaws that are hard to overcome.  Let’s look at some examples of hotel room insecurity and what you can do to mitigate them.

Sighthound Video Surveillance App

Physical security is an inherent part of information security. If an attacker can achieve physical access to your devices, you are already behind the power curve.  Maintaining physical control of your devices is maybe the most important step you can take to protect your data-at-rest.  However, there are some occasions when maintaining physical control is not possible or practical.  One of these occasions is during hotel stays.  Hotel rooms – and even their safes – are incredibly insecure (I’ll talk more about this in an upcoming post).  They are usually the best alternative to lugging your laptop around to dinner, out of drinks, or for a day at a local attraction. Rather than leave my laptop (and other stuff) totally undefended, I use a video surveillance app called Sighthound to keep an eye on things when I’m away.
