TRANSIENT STORAGE OFFERS EXTRA PROTECTION
There's a lot going on when you use your
computer and most of it occurs without you even knowing about it. Oh
sure, you go online, word process some documents, check your email,
play a few games and so on. But all of that is really only the part
on the surface, the part you get to see. What's really going
on, all the background stuff, the hard drive access, the
housekeeping functions that endeavor to keep everything running
smoothly, all of that happens beneath that surface and thank
goodness for that. You really don't need to know when the Registry
is being changed for example. You don't need to know anything
about these things to productively use the machine. But being
completely oblivious to these internal functions can also be a
recipe for disaster. Some preventative maintenance is needed on your
part to help keep things running smoothly.
You may not know a computer virus if you tripped over one but you
probably already know that you need an anti-virus program to protect
your PC from getting infected. Anti-spyware is another perfect
example of something you need to have as is a firewall when you go
online. It's pretty much a sure bet that without these safeguards in
place, it won't be very long before you experience your first
computer meltdown.
Antivirus, anti-spyware and firewall products are traditionally the
most popular in the software protection category. But there are
other products out there that try to protect using alternative
methods and I'm gratified to see them. The bad guys are always
trying to find methods of defeating the mainstream protection
products so it never hurts to supplement them with an additional
layer of protection, especially if that layer is something that
makes the battle a little less painless. I recently came across
something called Sandboxie and although the idea behind it is a
simple one, sometimes it's the simple ideas that can be the most
effective.
When you run any program on your computer, data flows between your
computer's memory and its hard drive which stores everything. The
problems begin to happen when something malicious gets written to
the hard drive. Sandboxie is a small utility that tries to prevent
that from happening. The metaphor they use is that of a sandbox. The
idea is that instead of letting an application read and write
directly to your hard drive, it reads and writes everything that
happens to a temporary holding area or sandbox. As the application
runs, it may read needed information directly from the hard drive
but it will never write to it. The idea is that when you first
install something new, you first try it out using the sandbox. If
something goes wrong or something bad happens, the transient nature
of the sandbox will allow you to throw out everything that was in
it. And when that happens, your computer is restored to the
condition before you installed the new product.
Let me say that this is not a perfect solution for all conditions.
Sometimes infections may not make themselves known for a long period
of time, if ever. So if you don't know that your computer has been
turned into a zombie for example, you won't know to throw out the
sandbox in the first place. Still, the concept has merit for certain
scenarios. A good one would be letting a friend use your computer
for a while. You want to insure that whatever he does with it, you
can just put it back the way it was by throwing out his sandbox.
Makes sense to me. I say give Sandboxie a try, especially because
it's free. You can register the program if you like it for $25 and
you'll get a lifetime registration that brings along some additional
abilities when you do so. These include being able to just sandbox
specific programs rather than the whole computer as well as running
multiple sandboxes instead of just one.
Sandboxie works only with Windows and is available for download at
