February 2012 - Say “No Thank You” to the New Toolbar

Have you ever had a new toolbar suddenly "appear" in your browser? Although it might not seem like you agreed to install it, the likelihood is that you did.

 

One of the most frustrating strategies companies use to deploy more toolbars relies on your not paying close attention when installing software or other programs on your computer.

 

For example, let's say you're installing an update to the popular Java runtime, which is software used by some websites to provide rich functionality beyond just displaying static pages.

 

The update consists of the normal installation program, and then proceeds to ask you the normal installation things, including agreeing to the software license.

 

Then another screen comes up and without reading it you're about to click Next.

 

Wait!  In doing so you would have been asking to have the Yahoo! toolbar installed.

 

Nothing against Yahoo, Java or Sun here, but this can be very annoying. It's not that the Yahoo toolbar is bad. It's actually a fine toolbar. The annoying part is this:

 

 

 

 

This installation is not the only case. During installation of many software packages - both initial installs and updates - the option to install a toolbar will often be selected by default. You have to click a box to opt out. This choice typically comes during the middle of the process when you're conditioned to hitting "next" just get it over with. If you're not paying attention once you're done suddenly a new toolbar will "appear." A toolbar you didn't realize you had actually agreed to.

 

Typically, installers include this option to earn profit. It's a way for those offering free software to recoup some of the cost. But this habit certainly shows up in paid for software as well.

 

This tactic is a perfect example of why it is important to pay attention during installations and updates. Read each step before clicking next or you might find you're about to "ask" for something you didn't really want at all.

January 2012 - How Do I Keep People From Finding Me on the Internet?

Do you wish you could erase yourself from the Internet? In other words, do you want to stop your name and information from showing up when people Google or search for you on the Internet? Sadly, you're not alone.  Not only is this disappointingly complex to do, ultimately... you can't.

What it boils down to is understanding how little control you have, what steps you can try, and how effective they may or may not be. But first, you should know that prevention is the only real cure.  Even then it's not at all complete.

You need to assume that everything you place on the Internet will remain there forever, and will be viewed in the worst light possible. To clarify, it may not be there forever, and may not be viewed in the worst light possible, but that's the safest way to look at how what you say, or do and post in public might be used. You do have control over some of what goes up on the web before it goes up, so exercise caution.

Still feel like posting those party photos?

How about the example we often hear: someone losing a job or job offer because they spoke their mind in a public post, posted unflattering photos of themselves, or otherwise made public information about themselves that they never should have--information that their employer or potential employer eventually found.

It happens all the time.

It happens to those who have the freedom of speech mentality: "I should be able to post and say and do whatever I want."  Absolutely. You should be able to. Go ahead. Post and say what you like. In most countries you have the right to say pretty much whatever you like. Just remember that freedom of speech does not mean freedom from consequences.

Chances are you're not going to get information removed from the Internet once the day comes that you decide it shouldn't be there.

Even preventing what you do and post may not be enough. What about other sources of information that relate to you?

You cannot control what others say or post about you. (Within the legal limits of harassment, libel and slander, of course, and even then within the limits of your own legal or justice system and your resources.)
Been mentioned in a newspaper? Listed in public records? Do you participate in discussion groups that are visible and/or archived publicly?

All of these are ways you can show up online. And there are plenty more. More than likely, all are places from which you probably can't remove yourself.

Still want to try? Here's what you can do:

Your first thought may be to try to get in touch with the search engine, but here's the fundamental problem: the search engine has nothing to do with it. Even though people may use the search engine to find the information, that information is not in the search engine itself. It's on one of the thousands of other sites on the Internet, and the search engine is merely in charge of finding it. The only way to truly remove yourself is to find each of those sites and ask them to remove the information that pertains to you.

It's common to want to have Google remove you from their index. There are two problems:


1. They won't. Google is a search engine, and their "job" is to report what can be found on other sites on the internet. They're simply showing you what's out there, but what's out there is not in their control.
2. Google is not the only game in town. Google is perhaps the most popular, but there are literally thousands of search engines on the Internet. From Bing to Yahoo, to many medium and smaller niche search engines, there are more search engines than you could ever count. Even if you could get Google to remove you from their results, which you cannot, you'd still be faced with all those other search engines that might
also be returning the same results that show your information on the internet.

Look out for a growing service area called "reputation management." These services will promise to remove you from the search results. They can't. If they tell you that they can, they're wrong. The information cannot been removed. The best that they can hope to accomplish is to push whatever it is you want to hide further down the results list when people use common search terms for you. At best it's simply somewhat harder to find... which may, or may not, be valuable to you.

It would be nice to think that you have control over the information that is placed on sites and services that you control on the web. But you don't. This is another way that this issue gets so complicated.

You might think that if you wanted to remove something about yourself that's been posted on your own website, all you need to do is exactly that - remove it. Problem solved.

Not so fast.

The "problem" is that there are other sites that take copies of the pages on your site and preserve them as a kind of historical record. Archive.org is a good example, but in fact there could once again be any number of sites archiving or duplicating information and many of them are doing it illegally. You can certainly remove the information from your site, but you have no control over what these other sites do with the information that they've already captured and made publicly accessible.

So what can you do?
• Well, you can use the search engines yourself to see where all the information about you is, and then contact all of those sites (not the search engines) and ask them to remove it.
• You can use a reputation management service to try and "bury" your information, making it harder, but not impossible to find. If that's enough for you.

And that's about it. Once something is on the Internet, you can pretty much plan on its being there for good.

In fact, it might be easier to change you: move, change your name, change all of your identifying information, and then make sure that as little of that new you as possible gets on the internet.

But even then, you'll probably show up somewhere.

December 2011 - How to Keep the Data on Your Laptop Secure

 

Understandably, the biggest fear most people have about losing their laptops, is not actually centered on the laptop itself. The biggest fear is having sensitive information end up in the wrong hands. Most can handle the material loss, but all those data in the hands of malicious individuals is scary!

There is a solution which is secure, fairly easy, and best of all, free.

Of course, you can just encrypt all of your data with different archiving tools which allow you to assign each file a password. The problem associated with this method is that these passwords are often easy to crack and this process is a pretty big hassle.

Instead, consider the free, open source program called TrueCrypt. This software provides industrial-strength encryption while being very easy to use.

TrueCrypt can be used many ways, but the two most common are:

• Encrypting an entire disk such as a floppy disc, USB thumb drive, or entire hard disk.

• Creating an encrypted virtual disk container or "volume".

The latter approach is the easiest for copying entire containers from machine to machine.

TrueCrypt simply mounts the encrypted virtual disk so that it appears as an additional drive on your laptop. You enter the pass phrase once when you mount the virtual drive and from then on everything read from there is decrypted and everything written there is encrypted automatically.

For example, you can have TrueCrypt generate a drive called C:/windows/secritstuff. Then, if someone were to look at that file directly, they'd see nothing but random gibberish as a result of the encryption. When you use TrueCrypt to mount the virtual drive (such as selecting the drive letter "P") then that drive - P: - would look just like any other disk on the machine. Every file placed in the drive is encrypted, so encryption becomes as easy as simply moving your sensitive files into that drive.

While the encrypted drive is mounted, the contents can be accessed in their unencrypted form by any program you wish to use to access them.

The trick is to set the drive so that it never mounts automatically. As your machine boots up the virtual drive would be nowhere to be found. The corresponding file C:/windows/secritstuff would be visible only as encrypted gibberish. Someone trying to access your files would only find that.

The data are not accessible until you use the TrueCrypt software to select the file at c:/windows/secritstuff, choose the drive to mount it as P: and type the correct pass phrase.

TrueCrypt also supports a variety of high-powered encryption algorithms. TrueCrypt documentation is obviously targeting the overly paranoid, including directions on how to use "plausible deniability" if a thief ever forced you to give them your password. Let's all hope that's just an extreme of little probability for most of us.
