Network Security - by John Feuerstein

Every day at closing time, we double check that coffee makers are turned off, arm fire and burglar alarms, lock doors and go home confident that our businesses will remain safely undisturbed until we return in the morning. As business owners, we pay close attention to office security. It is likewise important to pay close attention to our computer network security. Network security failures lead to costly business interruptions and critical data losses. Here are a few of the most common network security issues that we encounter in the field, and some ideas about correcting them.

• Put your file server in its proper place. This repository for all of your important business data does not belong under a table below the coffee maker in front of a heating vent. Servers do not like being kicked, spilled on, or accidentally unplugged. Keep your server in a secure (perhaps even locked) properly ventilated enclosure.
• UPS and I’m not talking about shipping packages. Plug all of your computers and network equipment into UPS (Uninterrupted Power Supply) devices with surge protection.
• There is always something going around. Don’t catch it. Your internet connection and email expose your system to computer viruses. Install virus protection software and configure it properly. Improperly configured virus protection is like no protection at all.
• Barbarians are at the gate! Hackers and internet anarchists target business networks of all sizes. Your best defense is a quality firewall properly configured. Do not skimp on this.
• Trust, but verify. Network monitoring has become increasingly popular. Network monitoring devices and software provide alerts when there is a performance or security concern. Monitoring can help IT professionals prevent problems and speed resolution when they do arise.
• Allen Ludden whispers, “The password is -- alligator.” Did you write your password on a post-it and stick on your monitor? Do employees share usernames and passwords? Is everybody an administrator? These are serious but common User Security Policy mistakes. User accounts with appropriate privileges can prevent disastrous consequences.
• Sometimes you must backup to go forward. Critical data loss can have costly consequences. Use software to automate scheduled backups. Store backup files both locally and remotely, and have a plan for rapid data recovery.

Now is the perfect time to double check your network security. If you do not have the technical resources in-house, schedule a Network Security Evaluation with a reputable IT support provider. This inexpensive precaution can prevent costly problems in the future.
