This is the way the world is going and the hackers and criminals are doing their usual evil deeds.
These are the threats to your business and some tips on how to combat them.
The Threats
Some but not all of the tactics that the bad guys deploy to do you damage
?Roaming Attackers: Attackers don't have to be located on a business's premises in order to access data on a wireless network. Criminals use network scanners, with a laptop or other portable device to sniff out wireless networks from a moving vehicle. This activity is called "wardriving". The same task performed while walking is called ?warwalking".
?Hidden Access Points: A hidden access point is one that exists without the permission or knowledge of the wireless network's owner. These are often installed by employees to create hidden wireless networks that circumvent any installed security measures.
?Evil Twin: Sometimes referred to as Wi-Phishing, an evil twin is a hidden access point that hides under a nearby network's name. The Evil Twin waits for an unsuspecting user to sign into the wrong access point and then steals the individual's data or attacks the computer. What fun these idiots have!
?Network Resource Theft: Freeloading to you and me. This is a business or individual located nearby and logging onto your network for free. It's a bit like hanging out my washing on your line to save me the cost of the rope.
Protection Methods
Lots of ways have sprung up to protect wireless networks. Here are some of the best known ones
?Firewalls: A properly configured, network firewall can effectively block intruders trying to enter a business's network via a wireless device.
?Security Standards: The first security standard named WEP (Wired Equivalent Privacy) was insecure and easily compromised. Newer specifications, such as WPA, WPA2 and IEEE 802.11i are much stronger security tools. Businesses with wireless networks should take full advantage of a least one of these technologies. Ask an expert rather than enhance your life by learning this yourself, is my suggestion
?Vulnerability Scanning: Use a network scanner yourself (just like the bad guys do) to uncover attacker-exploitable weaknesses in your wireless network, such as unsecured access points.
?Education: All employees should be trained in the proper use of wireless devices and instructed to report any unusual or suspicious activities they detect.
