Keep OS Patched
Could real people actually be as clueless as some of those characters we see in movies? sadly, you need no more evidence of that cliché than the average computer user. Even though he or she knows that an OS update is as critical as, say, nailing boards over your windows in a zombie apocalypse, many choose to ignore the updates until something crawls in and eats their brains. The most basic security step PC users should take—regardless of OS—is to install the latest updates. Yes, we know, it can be teeth-gritting—especially when the updates are larger than the original OS—but it’s necessary for patching holes being used by attackers to squeeze into your PC.
Keep Applications Patched
Even Microsoft haters have to admit the company has done an admirable job patching its operating systems in a reasonable amount of time. Because of this, many of the weak spots on a PC aren’t even the OS anymore, but rather the third-party applications. While Microsoft will patch its own products in Windows Update, it doesn’t do squat about anything else. With literally dozens of apps to check for updates every week,you can see where the problem lies. That’s why we run Secunia’s PSI Scanner. The free app runs in the background and checks your installed apps and plugins for available updates and then gives you a link of where to download the patch. The latest beta version will actually install some of the updates for you. The company also offers an online scanner but we don’t recommend it because it runs in Java.
Lose Windows XP
Windows XP was a great operating system but it’s now over 10 years old and it’s a popular target for attacks. Why? It’s not as secure as its replacements. It’s also where the money is—literally—with 51 percent of computers on the planet running it. Many attacks specifically target XP and ignore Windows Windows 7 and 8 completely. Unless you like to wrench on your OS all day, we recommend that you give XP the retirement it has earned.
Use a Virtualized Browser
Since the vast majority of attacks are coming from the browser, one of the safest ways to surf the web is from a virtualized browser or a virtual machine. One of the simplest ways to accomplish this task is to build a virtual machine using either virtual PC 2007 or VM Ware Player. Both are free, and both Microsoft and VM Ware offer free images that include browsers. Microsoft offers Vista and XP with IE8 installed and VM Ware offers Ubuntu with Firefox installed. Of the three options, VM ware’s is the most solid but folks not used tolinux might be thrown for a loop. Microsoft’s
images time out after three months, so you’ll have to download it again.
Restrict PC Access
for Others so, you’ve created this incredibly secure moat, ringed with razor wire, claymores, and mines. And then you let your 14-yearold nephew play some Flash games or “check email.” Right. The best solution is
to have visitors use a separate, secured guest PC. But if they must use your machine, make sure you have the guest account activated. Another option is to have them use a virtual machine. Once they’re done, simply shut down the VM and erase any trace of their activities. Or have them use your HTPC, where they’re working in the open instead of being left alone in your office.
