Encryption And Making Your System Secure
Posted by cotojo on April 25, 2007
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,
1) Encrypting your email
2) Encrypting your files
Two 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
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.
