Perhaps the most important defense is to be proactive in securing your WLAN.
Don’t wait for threats to emerge before taking action.
Now that you know the threats to your WLAN and some ways to deal with them, you can take what you know and put it to work.
Each vendor maintains patches and updates on its Web site.
You could go to every Web site and search for all the vulnerabilities that affect your devices.
You may even find most of what you’re looking for after quite a while.
The best place to start is the Security Focus Web site.
Security Focus maintains an exhaustive list of vulnerabilities for hardware and software from every vendor.
If it’s vulnerable, it’s listed on their site.
Often vulnerabilities are listed on Security Focus even before the developers of an application or device know about the problem.
In those rare cases when a company refuses to acknowledge an issue, this Web site may be the only place where you’ll find it listed.
Make it a habit to check the site regularly for new threats.
Many vendors will send you an email warning you of vulnerabilities if you took the time to register your product (and lets face it, most of us don’t).
For the 90 percent of users that use a Microsoft operating system, the Windows Update feature will help you keep the operating system patched and save you from becoming a casualty when the next worm surfaces.
Most cracker tools exploit holes that have not been patched.
If you don’t maintain your systems, you are remaining vulnerable when you should be safe.
Taking the time to patch software and update the firmware on devices will minimize your risk and reduce your headaches.
