Every week it seems we hear about another hacker attack or malicious virus that's plaguing computers and corporations around the world. It might be tempting for us to believe that these attacks are carried out only against large corporations and governments. But, the fact is that every computer connected to other computers, be it through the Internet or even a file on a floppy disk, is vulnerable to a host of security issues.

The facts show an increasing number of attacks across the world, and that number increases daily. Let's take a quick look at some common ways you can safeguard your business and your customers.

A virus is pretty easy to defend against with the right tools and vigilance, but once you've got one, it can be a frustrating and damaging experience. Here are some tips to help you avoid viruses:

• use virus protection software
  Update your virus definitions frequently. Have the software scan your system every time your turn on your computer, and scan every file you try to download.
• don't open unknown e-mail attachments
  Never open any e-mail attachment unless you know what it is. Even attachments in e-mails from colleagues can contain viruses, as some viruses are able to infiltrate an address list and spread automatically. Always scan files with anti-virus software before opening.
• exercise caution in downloading files
  If you download files be sure that the source is a legitimate and reputable one. Make sure that your anti-virus software checks the files on the download site. If you're unsure, don't download the file at all or download the file to a disk and test it with your own anti-virus software.
• watch out for hoaxes
  A growing number of messages circulating the Internet involve hoax viruses that don't actually exist. These hoaxes are spread by e-mail, and can be an annoyance to companies that have real security concerns. Before forwarding warnings to your entire mail list, check the validity of a virus alert to avoid causing any unnecessary alarm. There are many Web sites that track both legitimate viruses and hoaxes.

PC security

The easiest way for someone to break into your system is to walk up to your computer and start typing! Prevent "low tech" break-ins by logging out when you leave your computer, and lock your office if you can.

Another way to secure your PC is limit the number of accounts available on the machine. Delete inactive users. Make sure that people with log in privileges choose good passwords. Don't pick something obvious like your name or birthday. Also, don't use words that can be found in the dictionary. Good passwords contain numbers, letters (both upper and lower case), and punctuation characters.

It's also a good idea to prepare for the worst. Make sure your system is backed up regularly and keep the backup media secure.

network security

While the breach of a single PC is a problem, unauthorized access to your network - with its complete spectrum of files and information - has the potential to be a catastrophe. Confidential information ranging from customer proposals and pricing to employee data and earnings can be vulnerable to prying eyes if you aren't careful. Here are a few tips:

• get a firewall
  A firewall acts as a protective barrier between the outside world and your network.
• establish good network passwords
  Choose passwords that are not easy for others to guess. Provide staff with password guidelines and recommendations for password change dates.
• use access authentication
  Access authentication software works with your firewall to check the identity of anyone who tries to access your network.
• use network encryption
  Network encryption prevents anyone who doesn't hold a "code" from accessing information over the network.
