Internet security is important to businesses, governments, and individuals for a variety of reason. Most of these reasons, however, can all be related to one core threat – the loss of control.
Internet security is about protecting data, protecting equipment, and protecting yourself from the tedious and sometimes impossible task of trying to restore your computer to the way it was prior to the breach in security.
Whether the Internet user is the U.S. Department of defense or a teenager with a MySpace profile, Internet users have the desire to control and protect their personal and confidential information on the Internet.
There are a few key areas that Internet users need to protect and control:


Control of Access
Much of the information that is exchanged online is only intended for a few involved parties. If everything you ever typed was available for all to see, chances are that you wouldn’t be nearly as carefree with what you typed. Many Internet users have a false sense of security that their actions are anonymous online, but the truth is that a great deal of what occurs on the Internet leaves an electronic footprint.


When it comes to personal or confidential information, controlling access is a top priority. Teenagers using social networking sites need to be able to restrict access to those that they know and trust. Military institutions need to restrict access to those with qualifying military clearance. There are several other examples of the importance of controlling access. Effective use of encryption software can help, as can making sure that sensitive information is password protected. Internet Security may not be perfect, but it can keep a lot of unwanted visitors away.


Control of Information
With identity theft becoming one of the fastest growing crimes, your personal information needs to be closely guarded. The Internet is a haven for criminals looking for information that could become useful to them.
Phishing scams, for instance, attempt to trick Internet users into revealing sensitive information under the assumption that it’s being sent to a legitimate source. Think about how often credit card numbers are sent electronically, or about how often banking transactions are handled online. Allowing this information into the wrong hands could have serious financial consequences.


Control of infrastructure
Several Internet security measures and software programs are designed to protect your computer and its operating ability. Risks such as denial of service (DOS) attacks, worms, and Trojan horses threaten to interfere with a computer’s operating system.
Many of these threats are designed to overload your computer with the processing of information, rendering the computer essentially useless. These threats also pave the way for other viruses to enter your computer in the future.

Taking steps to strengthen your Internet security measures will increase your chances of losing control of the important elements described above. Anti-Virus software, updates and patches that become available to install, and generally being smart about the information you share and attempt to view online will help keep you computer and your information out of trouble and running efficiently.
