What Are The Main Computer Network Security Threats? By Derek Rogers At Isnare.com Ezine Articles

Whether you are looking to protect a small network in your home or one that is the foundation of your business, you will find that it is first important to understand what kind of threats you might be facing. As soon as you have a computer hooked up in order to connect to the network, you will find that there is a chance that it can be exposed to a number of different risks. When you are thinking about what you can do to make a system a great deal more secure, you will find that an understanding of the risks that you are vulnerable to is something that can help a great deal.

First and perhaps most obviously, is the threat of a virus. While the majority of viruses are simply annoying, there are definitely viruses that can damage your network's hardware, software, or both. For the most part, a virus is an executable file that will be spread by human means and will require someone to open it before it can do its work on the network. When looking at virus threats, it is worth understanding worms as well, which are considered a subset of viruses. Worms do not need human help to propagate themselves, and in fact one example of the way that they work is to turn your computer into an email server that will distribute copies of themselves.

When looking into network security threats, though, it is very important to consider what risks may be present from inside the system. First and foremost, the idea of bad architecture must be considered. If a network is mis-configured in the first place, it can be a very tempting target for people who are looking to get on it. One obvious example of this would be leaving a wireless network unsecured so that anyone with a network card could get onto it. This can certainly happen in a broader and more disastrous scope.

Interestingly enough, one of the most common measures taken to save time is also one that leaves network systems shockingly vulnerable. Consolidating a lot of services to one machine is a common measure for saving time and resources. It is easy to manage and simple to maintain, but if this single machine is compromised, there is a great deal of harm that can happen. While accidental failure is one thing, there is also the concern regarding the ease with which a single machine could be manipulated. In this case, the answer is frequently redundancy.

Computer network security is something that is very important, and if the information that you are safeguarding has anything to do with money or with personal information, it will achieve even a higher priority. Take some time and think about your system and think about whether it is vulnerable to any of the threats above. The more security that you can provide, the better off you will be. The protection of both your company and your customer depend on this aspect of your company's working, so always consider what network security means to you.
