Protect Yourself From Data Theft

OK, I may be a little paranoid, but maybe a little paranoia is acceptable when it comes to personal data security. On my home server I have attached a 1 TB external USB hard drive. It contains basically my entire digital life on it all the way back to papers I wrote in high school up through pictures of my wedding and the births of my children, to today. The thought of someone breaking into our house and stealing our stuff is scary enough, but to think that they would also have access to all of my digital info takes that fear to a whole 'nother level. Not that someone wants my sophomore paper on To Kill a Mocking Bird, but passwords, copies of drivers licenses, social security cards, birth certificates, and other stuff might be of interest to a person with malicious intents.


So to prevent the misuse of my data, I encrypted the entire hard drive. I used a Freeware program called TrueCrypt. It allows users to encrypt entire drives and/or file folder containers. I opted to encrypt the entire drive for my external storage device. When the power to the drive is disconnected, the USB is unplugged, or the computer is shut down, the encryption service disconnects and the drive must be remounted using the correct password. This should prevent the average smash and grab criminal from gaining access to the data inside the drive, should they even attempt to do so. I am not an authority on cyber crime, but would not be surprised if this was a common occurrence, or at least an emerging trend.

This setup makes it a little inconvenient since I have to enter the password to remount the drive when rebooting the computer. Unfortunately, it houses all of our stuff, so until it is mounted, the FTP, media libraries, and other content is unavailable. However, for the most part, the home server that it is connected to stays powered on. I also recently disabled automatic Windows updates which caused occasional unanticipated restarts. Also, the PC and the drive are hooked up to a UPS power backup to prevent disconnects and/or reboots from power flickers or short outages.

One way I am still vulnerable is if someone brings a PC to my house and plugs into my network, or if someone logs onto one of my PCs and actually sends out or saves out my files. Although, I am not expecting anyone to pull a Mission Impossible 6 on my data, I think I need to consider what I could do to close that gap.

Also, recently I have been wanting to upgrade my storage to RAID mirrored Network Attached Storage (NAS). But the next question I have is how do I keep someone from getting access to the data on those drives if stolen. Also, I would like my periodic backup to the drive in the fireproof safe to be completely automatic, and more frequent than every three months, which is how often I do it manually now. I think that NAS drives generally leave the data completely unprotected in terms of encryption and none of them offer an affordable theft and fire resistant enclosure. So, anyone that can connect to it will have access to the data. I don't know if the NAS devices can even be encrypted. Something to think about a little more.

Portable thumb drives are also important to protect. These are extremely easy to loose. Think about it, what would you do if someone had all of your thumb drive data? Do you even remember what all was on it? Would it make you vulnerable?

I decided to encrypt most of my thumb drive after I lost it for about a week. I keep a readme file on it with my contact information, so that if it is found, an honest person could return it. But not knowing where it was or who might have it was killing me. Was someone looking at my data; my budget, my contact lists? Was everyone else listed in my files exposed now because of me (keeping data on them and now loosing it?) To remedy this worry for files on my thumb drive I opted for an encrypted file container which takes up about two-thirds of the space on the device. This contains my portable files. The other third of the device contains the TrueCrypt installation executable (to install on other computers), a local thumb drive installation of TrueCrypt that can be run off the thumb drive itself, and a bit of unencrypted free space for quick file transfers. Now, I can sleep at night if I loose the device, knowing that if found, the only data available is my "return to me" readme file containing my contact information.

Some would argue for the use of cloud services for data storage, but I don't always have a fast internet connection, sometimes don't have any internet access, storage is often limited, and are those services really keeping your data secure? I prefer to keep my data under my control.

Overall I feel a lot safer with the systems that I have put in place to protect my data and recommend that you do the same, or similarly protect yourself, or at least consider what could happen if your data was made public. 

Help me disable my UPS alarms! Tripp-Lite OMNIVS1000

I have two Tripp-Lite OMNIVS1000 Uninterrupted Power Supplies (UPSs) in my house. As much as I love the fact that they condition the power for my electronics, regulate voltage swings, and provide backup power for short outages (which I believe extends the life of my electronics, see Protecting Your Electronic Hardware from the Power Company)...one thing drives me crazy. The "I am on battery power" audible alarm. See the video below.


It beeps with this piercing three ring tone every 10 seconds. This can be disabled manually by pressing one of the buttons. So, every time the power shuts off I have to jump (usually out of bed in the middle of the night) and run to shut the alarm off. But in the dark with the power off, it is easy to push the wrong button (there are two) and shut the unit off, which defeats the main purpose of having it for battery backup. If I manage to hit the right button and only mute it, it will finally, when the battery is nearly dead, generate another piercing solid tone. However this one cannot be disabled without shutting the unit completely down, or waiting it out until it shuts itself off. So when this happens in the middle of the night I need to get up and disable the audible alarm and if the outage persists, shut them down before the batteries go dead. It is a very manually intensive process, and I have two of them. You can imagine what happens when this occurs when I am out and my mom or a babysitter is home with the kids. I feel weird leaving an operating manual for my house for these unlikely contingencies, but it has happened before and I kind of feel bad not covering all scenarios.

I looked online for replacement UPS units but worry that they will have the same, or other, or more issues, and the ones I have actually do what I need them to do, I just don't want the noise. Even if I got another UPS, I would still probably use these units to backup additional devices, which would defeat the purpose of "replacing" them.

So in order to make an outage more bearable for all, I attempted to get this noise disabled. I was unable to find anything online to help me. If you are reading this, that is probably how you found this page. Hopefully I can at least save you the trouble of doing the same thing I did. So, I (safely) opened one of them up hoping to find a speaker that I could effortlessly unplug. I was unsuccessful. The control board is a single printed circuit board, with nothing that stands out to me as a tone generator, speaker, or noise maker. In addition all of the components are hard soldered to the board. Even when experimenting up close I can't tell where the noise was coming from. I am also unsure if I want to permanently disable the alarm or worse yet, break the unit by doing so, but at this point I am willing to try... if I only knew which doo-dad was the speaker module. Any guesses? I am including a picture below. I think it might be the white box at the top.

My next step might be flipping through my Digi-Key electrical parts catalog to see what a tone generator might look like.


One other gripe I have about this UPS is that it does not turn itself back on when power is restored, and I cannot automatically reboot my home server when the power comes back on (which would require a UPS reboot AND a PC reboot trigger). So whenever there is a >30 minute power outage, I need to push two buttons to reboot; the UPS restart and the computer restart,  which is extremely inconvenient if I am not home and trying to access home server resources. So I must choose between having a battery backup or having automatic reboot of my network when power is restored. If you have any thoughts or ideas please leave a comment below. Stay tuned and I will post an update as I learn more!

UPDATE: Disable via software! See below:

"Anonymous" left a link to LINK to an article that describes how to turn off the alarm via the Tripp Light software in "business mode". It seems to be effective. 

Backing Up Your Data

Recently a friend of mine lost about 12 months of his toddler’s photos when his hard drive crashed. With more and more of our important files being converted to electronic formats (pictures, home movies, tax records, and more) it is becoming critical to keep it backed up. Compared to the cost of digital SLR cameras, camera memory, computers, etc., ~$75 seems like a small price to pay to have, not just the photos, but all of your data backed up to a secondary removable drive. Although backing up can seem like a hassle, I have some scripts that make it a lot more convenient. I have a 1TB Western Digital Elements drive as my primary data drive on my server and a 500GB Western Digital Passport drive, which I backup monthly, in my Sentry 2 cubic foot Fire Safe. I also found a Sentry Waterproof Fire-Safe Hard Drive, but it isn’t theft resistant. There are also safes that enable the use of active drives inside such as the Sentry Data Storage Chest and the larger Sentry 2 cubic foot Fire Safe with USB which also has room for your other stuff and is a little less portable for theft resistance. I still question the data security of these drives, however, because if stolen, one could still access your data without opening the safe. Look for my other posts regarding encrypting portable drives. Another option is to backup offsite, there are pay services, but also Windows Live offers 25GB of backup with their SkyDrive, although economy bandwidth can make this a bit slow to use. Even if you don’t feel like you need a fire-safe backup, I would still recommend getting your data on two drives. Your hard drive will fail. It may be predictable, which a few of mine have been, where you can toggle the power, or disconnect and plug in the drive again to regain functionality, but this isn't always the case. And you could send your drive off to be professionally recovered, but these services can be expensive. Even if you are not concerned about fire or theft, I would recommend getting a backup drive for peace of mind, and to prevent a devastating drive failure.
