Nearly all businesses today use a computer network to standardize processes and improve communication and efficiency. The recent advent of affordable network solutions has been especially helpful for small and medium-size businesses (SMBs). The ability to use a centralized, easily updatable database and to network printers and scanners helps SMBs save time and money by eliminating redundancy. The ability to communicate quickly and easily improves efficiency, which improves the customer experience. Taken together, networks enable SMBs to grow the business to the next level affordably.

However, this interconnectivity can also cause security headaches. The central server and each workstation are all potential entry points for security threats that can then spread through the entire network. Most SMBs do not have an IT department; they have at best one IT person. At worst, the owner becomes the default "IT guy," but the owner may or may not really understand how the network works.

As a result, network security is often a hit-or-miss proposition in SMBs, but it should not be. All networks are subject to the same risks, regardless of size, and protection is vital to ensuring continued functioning of the business.

> Potential Security Risks <

* Viruses/malware

Viruses often arrive in emails, and other malware may hitch a ride on unauthorized software downloaded by an employee. New threats emerge constantly.

* Removable storage devices

An infected flash drive or external hard drive attached to one workstation can infect the entire network.

Any connections outside the network

The biggest threat is, of course, the internet. Within minutes of connecting to the internet a computer has been scanned by a hacker looking for a way in. The hacking risk continues to exist as long as any part of the network is listening for and accepting outside connections.

In addition, employees visiting dangerous websites may inadvertently infect their workstations. One compromised computer leaves the entire network vulnerable.

* Dishonest employees

No manager wants to believe it, but some employees do not have the company's best interests at heart. Be proactive and protect your business.

* Drive failure

Hardware fails. Ensure that a dead drive does not also spell the demise of your business.

> Impact of Security Breeches <

Network downtime, no matter the reason, negatively impacts business. If you are unable to conduct any business at all you lose not only revenue but customer
