Why go with a Wireless Security System?

/in /by

One reason to go wireless is obvious: Who wants all sorts of wires built under their house, which requires more than just the abilities of a recreational DIY enthusiast, like the old fashioned home security systems required? Not only is this a hairy, time consuming installation project, but a crook could clip the wires (if he gets into your house).

4WBenefits of Wireless

  • Installs in minutes.
  • Someone with basic DIY skills can install it.
  • All sorts of plans for all budgets.

Beware, though, that if a wireless system is not installed correctly, a burglar could get past it and doesn’t even have to enter your house to disable it.

However, do not let this turn you away, because when installed right, a wireless system has many benefits:

  • Full remote access from your smartphone or any connected device.
  • Easy install and easy removal if you are an apartment dweller.
  • Wireless systems can be as robust as wired and include security cameras.

You may be a candidate for wireless if:

  • You want to feel safer checking on the status of your home before going inside after being out for a while.
  • You have kids and must be away when they return home from school and you want to check in on them.
  • An elderly relative lives with you and you want to make periodic realtime checks.

Three Types of Wireless Connections

  • Landline. A wireless system can run through a landline, which means they are not dependent upon the Internet or a cellphone signal. It will stay activated during a power outage. Landline is cheaper than cellular or broadband wireless.
  • Cellular. Signals go to a cell tower and are faster than with landline. Seconds count in an emergency, and the faster signal means faster help. Cellular offers remote capabilities, being able to monitor your home far away on your smartphone.
  • Broadband. Instead of the signal being directed to a cell tower, it goes though the broadband Internet connection. This type of system is comparable in price to the cellular, and the signal is much faster than that of a landline connection.

What is Wardriving?

Wireless networks have certainly brought a lot of convenience to our lives, allowing us to work and surf from almost anywhere—home, cafes, airports and hotels around the globe. But unfortunately, wireless connectivity has also brought convenience to hackers because it gives them the opportunity to capture all data we type into our connected computers and devices through the air, and even take control of them.

4WWhile it may sound odd to worry about bad guys snatching our personal information from what seems to be thin air, it’s more common than we’d like to believe. In fact, there are hackers who drive around searching for unsecured wireless connections (networks) using a wireless laptop and portable global positioning system (GPS) with the sole purpose of stealing your information or using your network to perform bad deeds.

We call the act of cruising for unsecured wireless networks “war driving,” and it can cause some serious trouble for you if you haven’t taken steps to safeguard your home or small office networks.

Hackers that use this technique to access data from your computer—banking and personal information—that could lead to identity theft, financial loss, or even a criminal record (if they use your network for nefarious purposes). Any computer or mobile device that is connected to your unprotected network could be accessible to the hacker.

While these are scary scenarios, the good news is that there are ways to prevent “war drivers” from gaining access to your wireless network. Be sure to check your wireless router owner’s manual for instructions on how to properly enable and configure these tips.

  • Turn off your wireless network when you’re not home: This will minimize the chance of a hacker accessing your network.
  • Change the administrator’s password on your router: Router manufacturers usually assign a default user name and password allowing you to setup and configure the router. However, hackers often know these default logins, so it’s important to change the password to something more difficult to crack.
  • Enable encryption: You can set your router to allow access only to those users who enter the correct password. These passwords are encrypted (scrambled) when they are transmitted so that hackers who try to intercept your connection can’t read the information.
  • Use a firewall: Firewalls can greatly reduce the chance of outsiders penetrating your network since they monitor attempts to access your system and block communications from unapproved sources. So, make sure to use the firewall that comes with your security software to provide an extra layer of defense.

Although war driving is a real security threat, it doesn’t have to be a hazard to your home wireless network. With a few precautions, or “defensive driving” measures, you can keep your network and your data locked down.

Hacking Wireless for Identity Theft

/0 Comments/in /by

The ability to connect wirelessly has a lot to do with the indispensability of the Internet in our daily lives. Wireless Internet is available in our homes, offices, cafes, restaurants, parks, hotels, airports, cars, and even airplanes. The mobility factor allows us to work anytime, anywhere, on numerous devices. “Being connected” is at an all-time high.

Wireless Internet is amazing. But is it safe?

The short answer is: no. Wi-Fi was born to be convenient, not secure. Unsecured, unprotected wireless is everywhere. When a device connects to unprotected Wi-Fi, all the data stored on that device is available to a hacker with the proper sniffing tools.

The longer answer is: it depends on what kind of wireless we’re talking about. I’m going to speak in generalizations, since most of this is debatable and at this point, there are no absolutes when it comes to wireless security. So here we go.

Free, unsecured Wi-Fi is the least secure. Any Wi-Fi connection, whether in public, at home, or in the office, that is shared with anyone with any wireless device, lacks encryption of the data packets streaming from the connected devices.

A simple Firefox add-on called Firesheep can allow anyone with a Firefox browser to sniff out other devices using the same Internet connection, and to spy on their browser activity. Even if the victim’s login is encrypted, once they visit an unencrypted site, their data becomes vulnerable.

Home or office Wi-Fi with a WEP encryption is slightly more secure. Wired Equivalent Privacy was introduced in 1997 and is the original version of wireless network security. But WEP has been cracked, hacked, and decimated.

Home or office Wi-Fi with a WPA encryption is better. Wi-Fi Protected Access is a certification program that was created in response to several serious weaknesses researchers found in WEP, the previous system. WPA and WPA2 are tougher to crack, but not impossible.

Mobile Broadband has a degree of encryption that has been cracked, but the necessary hardware isn’t widely deployed by criminals. Researchers have demonstrated how the system can be hacked, but it’s still more secure than other options.

For the most security, use WPA2 wireless Internet from a home or office environment that isn’t internally shared. If you must go online while traveling, use your carrier’s mobile broadband and forgo the hotel or café’s free wireless.
Identity theft can happen to anyone, regardless of how they connect to the Internet.
