Network Security


Just as you lock the doors of your house, it’s important to put systems in place that protect your network. Network security is an essential part of building a network, but it’s not difficult. Here’s a list of some of the most practical, effective things that you can do to help keep your network secure.

Use Your Router’s Features
Your first line of defense for network security is your router. The router can prevent unwanted and unsolicited Internet traffic from intruding into your network. It also secures your wireless network and helps prevent access by unauthorized devices such as your neighbours’ computers. Make sure your router’s security settings are enabled.

Set Up a Firewall
A firewall is a software package that runs on your computers to help keep intruders out. Firewalls provide additional protection, but because no one thing can detect or stop all attacks, it’s important to use firewalls in conjunction with other security methods.

Equip Virus and Spyware Protection Software
Even with your best efforts, you never know what’s going to get through your firewall, so be sure to keep your spyware detection, antivirus and security software current on all computers on your network. Many software packages support automatic updates, so be sure to approve these updates when prompted. see our free software download page.


Don’t Open Email from Strangers
If you wouldn’t eat their candy, you shouldn’t open their email attachments. Before opening any attachments, be sure you know who sent the message. Be careful even if the email originated from a familiar address. For example, the Melissa virus used personal address books to send out malicious executable programs. Email robot viruses can mask the true source of the message.

If you’re bound and determined to open an attachment of questionable origin, you’re taking your chances. At least take these precautions:

  • Make sure your virus definitions are up-to-date
  • Save the file to your hard disk
  • Scan the file using your antivirus software
  • Disconnect your computer’s network connection
  • Open the file

Don’t Run Programs of Unknown Origin
It’s not really safe to click on attachments that come in email, unless you know exactly where the message came from and that it is safe.

Some malicious viruses, called Trojan horse programs, hide executable files in email. You don’t want to open one. And, you certainly don’t want to be responsible for sending them to your friends or coworkers.

Keep Patches Current
Patches are created by manufacturers to fix vulnerabilities, or holes, in their software. Many applications will automatically check for available updates, and many vendors offer automatic update notification through their mailing lists. When a patch is necessary, you can usually download it from the manufacturer’s website.

Back It Up
Keep copies of important files on removable media such as CDs, DVDs, USB or network attached storage (NAS). Use software backup tools if available, and store the backups away from the computer. In fact, it may be preferable to store your backup someplace not in your home. Dell offers DataSafe online backup, which can make this entire process easy. click here for more information on data backups.
