How Can I Use A Wi-Fi Network Scanner To Protect My Home Network?

protect your network with a WiFi scanner

When we are at work, we become used to the amount of security that is around to protect the company’s data.

From when you walk past the security guard at the front desk in the morning to when you try to log onto myspace and the company has it blocked.

Security is usually everywhere when it comes to the corporate environment.

It is no wonder that people may get fed up and, by the time they return home, they just want to relax and forget about the hassles of security.

Unfortunately in the world we live in, anywhere you have a wireless network, security must be an issue.

Corporate Security Tools

Luckily there are some corporate security tools that are available for free that you can utilize to secure your own home network.

Using a Wi Fi network scanner is a good tool to help accomplish this goal.

A Wi fi network scanner is any tool that allows you to scan a wireless network frequency and gather information about it.

When a wireless signal transmits, it is not only sending out your data packets from surfing the internet, it is also sending out information about your network.

It tells any person with the right tools to pick it up, the networks name, what kind of encryption you are using, if you have any encryption at all, and also the signal strength.

There are other items that the network will expose but this is the main information that it will give out, that your attackers can use against you.

This may not seem like much but this a lot of information to a person who may be trying to crack into your network.

This allows them to pick the right tools for the job.

Having the right tools makes it a lot easier to them to get in.

If you you use a WiFi network scanner to analyze your own signal, you are now able to see everything that a bad guy would be able to see when they are trying to penetrate your system.

Having this knowledge grants you a lot of power.

Closing The Holes In Your Network

Just as the bad guy would use this information to break into your network, you could use it to close any holes that might be there.

This allows you to be one step ahead of the bad guys at all times.

Some software that is popular for network scanning can be found in the following places –

All of these tools are used by professionals when they are out in the field.

If you are using Windows you can download them individually.

If you are adept at using Linux you can use a security distro by the name of BackTrack.

It will have all of these programs already loaded in and ready to use.

You can even use Backtrack as a live CD which will allow you to use it without installing anything.

So hopefully I have shown you how scanning your own home network can have security benefits.

I know it can be a hassle but the piece of mind that comes from knowing you are secured is surely worth it.

  1. Maybe we can add inSSIDer (http://www.metageek.net/products/inssider). Wi-Fi network scanner for Windows Vista and Windows XP. Because NetStumbler doesn’t work well with Vista and 64-bit XP.

    • Well, you did just add it Mourad.

      Thats a good addition too, and a timely reminder to myself not to ignore older operating systems which are still used by many people!
