Are You Using Adequate Protection?

Do you wonder if the data on your hard drive is truly protected from technological intruders? Apple has produced a variety of resources that can protect your files from unwanted hard drive peepers. However, just how secure are these methods of file protection?

First, let’s look at the most common form of user file protection: the administrator password. Created when Mac OS is initially installed, this password prevents unauthorized users from accessing the files on your account… or does it? A simple click in the Reset Password Utility after booting from the Mac OS DVD proves otherwise. As long as the DVD is the correct version of Mac OS, it can boot any system with that corresponding OS. Resetting the password only requires entering a new password, which becomes the new administrator password. So basically, all anyone would need to access an account that is simply password protected is the correct version of Mac OS installation DVD (this can also be accomplished using a string of commands in Single User mode—no DVD needed!). One thing to note is that the Keychain Access utility will not be viewable with this new password.

Now is when all the extra-protected Mac users say “Hah! everyone knows that. That’s why all my files are heavily protected by a firmware password.” In which case the intruder would pull out one stick of RAM, and boot the computer, bypassing the firmware password.

Now the real heavy hitters come out. FileVault is a file encrypting tool that works on the corresponding user’s home folder, encrypting it when the user is logged out. Nothing is for sure, but as far as the research I have done, FileVault is basically un-hackable. Knowing this, if you decide to use FileVault on your account, you had better remember that password.

So, are you using adequate protection? The first question I asked myself while trying to accurately answer this was: Do I really care if someone could potentially have access to my files? The answer is no. So in short, am I protected from potential technological intruders? Nope, not really, my information may be easily hacked into. However, is my protection adequate enough for the sensitivity of the files on my hard drive? Totally. Not satisfied? Well, if you truly believe the data on your hard drive is sensitive enough to warrant it, then FileVault it up.

  • There's an App for That!

    As the poet said: “There’s an app for that!” Sure there are LOTS of apps out there but which one should you choose? Since Martin Luther King, Jr. Day weekend is a big weekend for getting out on the slopes, I’ve decided to focus on some of the most popular ski and snow apps out there. I can’t take all the credit as we have quite a few outdoor pups here at Small Dog headquarters. Keep an eye out if you’re at Sugarbush this weekend as that is where we like to go play. If you’re planning on staying right here in Vermont Ski Vermont has highlighted some fun events as well as deals in their latest blog post here and I thought it was worth sharing.

    Find My Friends

    No matter how hard groups try to stay together on the mountain, inevitably, at some point during the day, somebody’s going to get lost. After all, it can be hard to keep up with quick friends who fancy themselves racers (I’m looking at you, Will), foggy conditions make it hard to see, and sometimes, people just want to ski different trails or get inside for a quick beer break. This app uses GPS tracking so you can locate friends and family on a user-friendly map.

    Instagram

    Although this app doesn’t necessarily offer ski-specific features, it sure is a great way to daydream about the slopes and keep your followers updated about all the great tracks you’re making. Explore hashtages like #skiing, #powder, or even find pictures of your favorite mountain. It’s a fun way to see awesome pictures of the slopes, document your own travels, and even meet other skiers and riders. Be sure to follow us @hellosmalldog!

    VSCO

    VSCO Cam has quickly emerged as the premier mobile photography app for iPhone photography, and hasn’t dropped out of the top 15 in the App Store’s Photography and Video category since it launched. If you are looking for a way to make your photos come to life before posting on other social media sites this is the app for you. VSCO Cam is the best way to shoot, edit, and share your photographs. As one app reviews states: “it provides a more thorough photo editing and filter options than photo sharing apps.”

    SkiTracks

    Using your phone’s map and GPS tracking abilities, this 99-cent app shows you exactly where you’ve skied on a satellite map, while also tracking distance, speed, altitude, duration, and more. Plus, its uses a minimal amount of battery life, so you can keep it running and still attend to your texts and calls, without worrying about running out of juice.

    Resort Specific Apps

    Many larger ski resorts have developed their own free apps. These usually offer a lot of the same tracking and snow report features as the general apps. However an app such as the Sugarbush app can help you navigate your way around the slopes, lodges, activities, weather reports, live camera feeds, and much more.
    Example: I always check the Sugarbush VT app before heading to the mountain so I can see which trails have been groomed, lift statuses, the lines, as well as weather and most importantly the wind chill so I can layer accordingly.

    Maprika

    Maprika lets you see where you are on real maps, like the ones that say “you are here” at the top of the lift. Easily locate your friends and family, and stay informed about the places you’re going. The coolest part about this app is that Maprika maps are saved to the phone’s memory, allowing for use in out-of-service areas. This app also allows you to find nearby businesses. As Dean says “it’s kind of like Yelp! for ski resorts, great when you are trying to get to know a new resort’s trail map.”

    Liftopia

    Purchase your lift tickets and or rentals in advance and save. Select from more than 150 resorts. This free app, “Liftopia Ski Reports, Snow Conditions and Ultimate Lift Ticket Deal Engine for iPhone and iPod touch,” though hard to remember provides an easy tool for showing a receipt at the ticket window, rather than having to deal with printing out a paper voucher (welcome to the 21st century!). Be sure you read the fine print for blackout dates before you show up at the mountain to redeem your deal. With deals like these, why not try a new mountain out!

    Spotify

    If you are one of those people that like to listen to tunes in the background while safely carving some edges I guarantee Spotify has a playlist for you! You can browse playlists for every mood and genre. The discover page will constantly suggest new music for you based on what you’re listening to and it’s all free! With playlists like “Ski” with over 500 songs, how could you go wrong?

    Editors note : Your iPhone is just like you, it really hates the bitter cold. When the temperature drops below freezing, iPhones can start malfunctioning: Your smartphone might not sense your touch, the battery dies faster and, if it’s cold enough, it will simply shut off. On its website, Apple suggests that you only use your (4th generation or later) iPhone in environments between 32º and 95º F, since “low- or high-temperature conditions might temporarily shorten battery life or cause the device to alter its behavior to regulate its temperature.”
