Computer Network Security Solutions

These days, every company of substantial size that uses computers to do business needs a network administrator. Due to the huge number of issues associated with having a network, the process of maintaining and keeping it up to date is a full time job, requiring the focused attention of a qualified person. In the 21st century, without careful monitoring by a trained eye, business networks are vulnerable to a wide variety of Web based threats that are not only nuisances, but can also cause major disruptions and even compromise the security of the company.

For this reason, network security is high among the top issues facing the modern business world, and it is the issue that earns the network administrator her bread and butter. In the early years of the Internet, business owners and CEOs learned that it was best not to leave network security in the hands of each employee. After all, as we all know, it’s nearly impossible to keep employees from using the Internet for personal reasons, at least without seriously risking the loss of their goodwill and loyalty. All except the most stubborn bosses have long accepted that there will be some personal Internet use at work, and most have moved on.

In fact, many companies are finding that the best course of action is to put the job of network security entirely into the hands of the network administrator, instead of leaving it up to everyone. Rather than installing antivirus, antispam, and antispyware software on each computer, experts have shown that the optimal setup is to install all security software at the network level. This makes it far easier to make all-encompassing network security updates, and it centralizes control of technical and security issues all in one place, where one person can solve problems without having to jump from computer to computer.

The opposite situation — to put network security in the hands of each and every employee — is inefficient and can lead to disastrous results for the company and the network. Particularly given all of the personal Web activities that go on in the average company, to depend on each employee to maintain a high level of security is asking a lot, and risking a lot more.

On the network level, the first necessary step toward network security is to create an authentication system that requires a unique username and password for each network user to log on. One level above that, firewall protection is necessary to ensure that outside entities are not invading the network through hidden access points. Both network authentication systems and firewalls are available from a number of software providers, and they are essentially the foundation of any network security system.

On a broader scale, network security requires a great deal of software specially designed to update itself according to the ever-changing and evolving security threats on the web. These come in the form of antivirus, antispam, and antispyware programs, all of which often can be found in useful packages. In particular, enterprise network security packages are designed to combat security threats before they come into contact with the network, rather than after. Under enterprise software, these threats will never even make it through to the computers on the network.

Meanwhile, one of the best and most important aspects of high quality network security software packages is the self updating feature. In today’s Web climate, software that cannot update itself becomes obsolete almost instantly. For this reason, many of the same companies that sell network security software also maintain constantly updating databases of virus definitions and other threats. When choosing which software to use, this is an essential feature to keep in mind.
