Networking For Dummies

Security techniques, such as physical security, user account security, server security, and locking down your servers are child's play compared to the most difficult job of network security: securing your network's users. All the best-laid security plans will go for naught if your users write their passwords on sticky notes and post them on their computers.

The key to securing your network users is to create a written network security policy and to stick to it. Have a meeting with everyone to go over the security policy to make sure that everyone understands the rules. Also, make sure to have consequences when violations occur.

Here are some suggestions for some basic security rules that can be incorporated into your security policy:

• Never write down your password or give it to someone else.

• Accounts shouldn't be shared. Never use someone else's account to access a resource that you can't access under your own account. If you need access to some network resource that isn't available to you, formally request access under your own account.

• Likewise, never give your account information to a co-worker so that he or she can access a needed resource. Your co-worker should instead formally request access under his or her own account.

• Don't install any software or hardware on your computer without first obtaining permission. This especially includes wireless access devices or modems.

• Don't enable file and printer sharing on workstations without first getting permission.

• Never attempt to disable or bypass the network's security features.
