Security Problems With Home Network Systems

It is important to familiarize yourself with the security features of your router.

Home networks can provide you with entertainment, easy access to information and email. They can also provide cyber-criminals access to your personal information if you have not secured your network properly. A number of potential vulnerabilities are inherent to a home network, and hackers can compromise it in many ways.

Weak Security Key

Your home network's security key is your first line of defense when it comes to securing your network. You can expose yourself to unnecessary risk if you choose a security key that is too short or is easy to guess. For example, if your security key is based on commonly known facts, such as your date of birth or your anniversary, it may be possible for others to guess it. In such a case, you may want to consider changing the key. Make the key as long as possible and choose letters and numbers that mean nothing to you.

The Firewall

Aside from weak security keys, the next largest issue with home network security that you may encounter is the lack of a firewall. A firewall is essentially a barricade that allows you access to the Internet while blocking outsiders from entering your computer. Without an adequate firewall, you risk exposing your personal data to anyone who is willing to look for it. Windows comes with a firewall, but this firewall can be turned off. If you do not use any additional firewall software or hardware, you may want to manually check all computers on the network to ensure that Windows Firewall is actively protecting you.

Backdoor Programs

If your network is compromised, even for a very short amount of time, cyber-criminals can infect the computers on it with backdoor programs. These programs essentially hold your network open to more malicious threats. Examples of backdoor programs include Back Oriface, SubSeven and NetBus. You may be able to remove these unwanted programs with antivirus software; however, you will have to seal the breach in your network's security for the fix to have a lasting effect. Networks that are most vulnerable to this type of attack use the older WEP security protocol. You can get more protection with the newer WPA protocol. Routers display which type of security they offer on their packaging.

Default Passwords

Wireless routers allow you to broadcast your Internet signal across your home or office, and they typically allow you to log into an interface through your Web browser. The first time you do this, you will likely use a default password that is provided to you by the router manufacturer. It is essential that you change this default password to something stronger as soon as you set your network up. Cyber-criminals make it their business to know the default password for all router manufacturers. If you still have the password set to default, this may be all the cyber-criminals need to enter your network and access your data.
