10 tips to secure your small business network

September 9th, 2006 · No Comments


Maintaining a secure small business or home network isn’t easy, and even for an old hand in IT, it hand.gifstill takes time and energy to keep things locked down. Here are 10 of the most critical steps you can take to keep your data from ending up elsewhere, and none of them take much time or effort to accomplish.

1. Use encryption on your wireless access points (AP). Many site surveys have found half or more of all wireless networks are wide open, ripe for anyone to gather all the traffic and perhaps record your sensitive information by sitting in a nearby parked car. Some people mess around with locking down MAC addresses, but that gets unwieldy and a better solution would be to use WPA2 encryption. WPA2 is far better than other encryption methods that are more easily broken into.

2. If you have a wireless network, make sure to hide your SSID (service set identifier), or at least change its name to something common. All wireless routers should have obscure IDs when they announce themselves to the world. Rather than put in any real information that can make it clear who owns the router or that can divulge your location or business name, such as "Acme Systems, here on the 4th floor" or the product name like "Netgear," use something innocuous like "wireless" or "router1" that doesn’t give away anything really critical. In my last apartment, I had neighbors who used their apartment numbers for their IDs, making it real easy to figure out who’s router was where. 10 tips to secure your small business network
