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."

2006 Security Watch - What is this year going to have in store for us?

2006 Security Watch - What is this year going to have in store for us?

There is a lot going on in the information security space. 2006 looks to be an interesting year in these regards. Below are some things to watch for in 2006, some of them are good and, unfortunately, some aren’t.  

First the good news:

- We are getting a lot more serious about our security. This has a lot of reasons behind it. For example, new privacy laws are mandating organizations to tighten their security.  Look to see more consumer privacy laws passed in the coming year and more tightening of security systems.

- Authentication requirements are increasing. This is closing in large security holes.  Corporations are requiring a great deal more of authentication to get into secure systems (this also is on the bad news side)

- There is a plethora of sophisticated programs to help us be more secure and they will continue to get better. Competition right now is strong in the security industry sparking a lot of innovation.

- ISPs are now taking on the responsibility to help us with our security. Take AOL's recent commercials as a good sign that others will follow the trend.

Now the bad news:

- Securing our networks is costing us.  Most companies are globalizing their organizations and making them secure costs a lot of money.  It will get worse before it gets better.

- Authentication requirements are increasing. This is getting claustrophobic.  Corporations are requiring a great deal more authentication to get into secure systems (This is also on the good news side) Unfortunately, for the end user, it is one more thing to be unhappy about, not unlike airport security lines.

- Hackers are getting more sophisticated.  For example, Botnets are becoming more complex and harder and harder to catch and stop. Do a search on botnets on the Internet. They really are causing a whole lot of problems, but it does not stop there. The number of viruses and malware out there is staggering.
