There was a time when computers weren’t something ordinary people could afford. Back then, only the rich could buy them and the only networks in the world were those run by governments or large companies. Today, the picture is most certainly different. An average family’s home can have a network of computers owned by each family member and their Internet connections are fast and topnotch. Some families even use wireless computers and though cost is no longer an issue, information security definitely is.

What makes wireless networks sensitive sometimes is the fact that signals can go everywhere and are very hard to detect. This makes hackers very happy then, because now, they can hack any wirelessly connected computer and very easily at that. There’s no need to install Trojans or keyloggers. They just have to connect to that wireless network with their own laptop and start stealing information from those that are already connected. This is why wireless security should never be taken for granted. Imagine having a close neighbor connecting to your network without your permission. The risks are always there but it doesn’t mean wireless networking is bad altogether.

In fact, only unsecured wireless networks can be a headache which means as long as you secure yours, you shouldn’t have any problem. If you’re not exactly technically savvy, you might think it’s some complicated task that needs an expert to do. On the contrary, you can do it on your own and quite simply.

First off, because networks run on ID’s, you need to secure your own network’s ID so unauthorized access is prevented. Laptops will come with a default SSID (Service Set Identifier) or ESSID (Extended Service Set Identifier). If you don’t customize it, you can expect hackers to come prying in because it’s actually very easy for them to research on the default identifiers for each wireless computer manufacturer. This is why it’s extremely important that you change you SSID or ESSID into something unique to you.

Then you need to disable Identifier Broadcasting so you don’t get to announce to the whole world that you’ve got this wireless network that just about anyone out there could hack into. A manual that comes with your device will have instructions for this.

The third step in securing your wireless network is to enable Encryption so only authorized people able to access your information. There are actually two types of encryption you can use – WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access). For maximum security, it’s better to go for WPA which provides stronger protection than WEP which has many flaws and is quite easy to crack.

Firewalls are, of course, basic to every Internet security campaign, whether wired or wireless, so check your manual and set up your firewall to block unwanted traffic. Anti-virus software as well as anti-spyware and anti-adware should also be installed and updated regularly to ensure maximum protection.

As a final step, change your default password into some unique to you. Refrain from using birth dates and anniversaries which are pretty easy to crack. The most secure password could be a random combination of letters, characters and numbers.

As a general online security measure, an IP hiding software just might be very helpful. Because it allows you to surf with fake a IP address, you don’t leave a trail for hackers to follow back to you. This way, you keep these unwanted elements at bay and you simply enjoy the added freedom to your Internet activities.
