What does encryption do for me?

Encryption and cryptographic software has been used in many different ways to make systems more secure. This article discusses only a few ways that such software can make your system more secure, including:

1) Encrypting your email

2) Encrypting your files

To programs are mentioned that will help encrypt information. There are many more programs out there that will help, but these programs are good and a good place to start as any. They have the added benefit of both being free with source code available.

Will encryption stop people from accessing my information?

Encryption simply makes it harder for people to gain access to important information, like passwords or sensitive information in a file. The first thing you should know about encryption is that the algorithm that is used to encrypt can be simple or more complex and that affects how securely what you have encrypted is protected. Encryption systems have been broken when the method of encryption is understood by hackers and is easy to break.

Why bother to encrypt my email?

It should be noted that email is far less secure than paper mail for two very good reasons: first, electronic data can be accessed easily over an Internet and secondly, electronic data is really simple to copy. There is a very good chance that someone has snooped around in your email despite your best intentions to stop it.

How do I go about encrypting my email?

There are many programs out there that can help you encrypt your email. A very popular one is PGP (Pretty Good Privacy) or its Gnu offshoot GPG.

PGP (http://www.pgpi.org/) self-describes itself this way: This "is a program that gives your electronic mail something that it otherwise doesn't have: Privacy. It does this by encrypting your mail so that nobody but the intended person can read it. When encrypted, the message looks like a meaningless jumble of random characters. PGP has proven itself quite capable of resisting even the most sophisticated forms of analysis aimed at reading the encrypted text."

Why bother to encrypt my files?

The answer to this boils down to what you store on your computer. If you have financial data with important information like social security numbers, email addresses, account numbers and passwords, then you open yourself up to losing very valuable information. Most corporate Internet security employees will attest to the widespread theft of very valuable information. As long as you are connected to the Internet you are vulnerable.

How do I go about encrypting my files?

AxCrypt File Encryption Software (http://axcrypt.sourceforge.net/) Self-described as "Free Personal Privacy and Security for Windows 98/ME/NT/2K/XP with AES-128 File Encryption, Compression and transparent Decrypt and Open in the original application."

Protection You Can Afford

There are numerous ways you can lose the information on your computer. Your child decides to play Chopin on your keyboard, a power surge, lightening, a virus, or even simple equipment failure. Therefore, backing up the contents of your hard drive is an absolute MUST. By regularly making backup copies of your files and storing them in a separate location, you can typically get some, if not all, of your information back in the event your computer crashes.

While a regular backup to floppy, CD, or zip drive will save your files, wouldn’t it be great if you could create an exact copy (a drive image) of your hard disk? That means backups of all your files, programs, and user settings. This would definitely save you time when it came to reloading. Acronis may be able to help.

Acronis True Image 9.0 is a robust disk-imaging utility software that copies the entire contents of your hard drive including data and operating system files, personalized settings, and more, onto another disk or disk partition. Its layout is easy to use and navigate. It also includes wizards which can walk you through both backing up and restoring your computer. Highlighted features include:

• Secure Zone — allows you to save data to a special hidden partition located on your hard drive which would eliminate the need to purchase an extra hard drive.
• PC Cloning — you can upgrade to a new system disk without needing to reinstall the operating system and applications, or configure user settings.
• Acronis Snap Restore - lightening-speed restore of your PC from an image. You can start working in seconds while your system is still being restored.

Acronis provides a free test-drive of its product and a 30-day money back guarantee. When you are ready to purchase, you can either download for $49.99, or if you so desire, order a boxed version for $59.99. With Acronis True Image Home 9.0, you can rest easy that your family pictures, personal documents, tax returns, resumes, and other important information will not be lost forever.

Surfing the Web Anonymously – Questions to Ask

When you surf the web it is possible to learn information about you even when you don't want to advertise who you are. This is true even if your system contains no virus or malware software. Specifically information that is easily available online includes your IP address, your country (and often more location information based on IP address), what computer system you are on, what browser you use, your browser history, and other information. It gets worse. People can get your computer's name and even find out your name if your machine supports programs like finger or identd. Also, cookies can track your habits as you move from machine to machine.

How do people get this basic information about you?

When you visit another web site, information about you can be retrieved. Basically, information is intercepted and used by others to track your Internet activities.

How do you stop this from happening?

First of all, it is possible to serf the web anonymously and thereby stop leaving a trail for others to find. Note that this is not fool-proof, but it makes it much harder for people to know who you are. There are products called anonymous proxy servers that help protect you. The anonymous proxy server replaces your Internet address for its own. This has the effect of hiding your IP address and making it much harder for people to track you.

How do I get an anonymous proxy server?

There are many vendors who sell anonymous proxy servers. There are also free proxy servers available to you. Two such products are ShadowSurf and Guardster. Guardster (http://www.guardster.com/) offers various services for anonymous and secure access to the web, some paid as well as a free service. ShadowSurf (http://www.shadowsurf.com/) ShadowSurf provides anonymous surfing at their site for free. Go to it and you will find a box to enter a URL that you want no one to track. There are many others, but here are two that are frequently used.

Another interesting product, given the recent news about the Google search engine filtering its findings for the Chinese government, is Anonymizer (http://www.anonymizer.com). This company, among others, recently (Feb 1st, 2006) pressed that it "is developing a new anti-censorship solution that will enable Chinese citizens to safely access the entire Internet filter-free" (http://www.anonymizer.com/consumer/media/press_releases/02012006.html).

Does an anonymous proxy server make you 100% safe?

No. Still, you are much better off if you use such technology.

What other things should I be concerned about when trying to keep my private information private?

Three other items come to mind when trying to keep your information private. First, you can use an encrypted connection to hide your surfing. This article does not go into detail on this, but search the web and you will find a lot of information on this. Secondly, delete cookies after each session. Third, you can configure your browser to remove JavaScript, Java, and active content. This actually leads to limitations, so you need to think about the cost/benefit of this course of action.

Anything else?

Wishing you happy and safe surfing!
