Wireless computer security and network privacy

Computer network security is important but the truth is, full security is unattainable as of present time even using firewalls. However, the level of security is increased when using a wireless computer network. As compared to wired networks, wireless computer networks have an additional point of complexity. Though wireless networking does not completely prevent interception, it is secure enough to be used in homes and even businesses. Wireless networks have security features such as 128-bit WEP and WPA that can encrypt network traffic making it difficult to be deciphered. In addition to that, routers which are wireless as well as the access points include access control tools like MAC address filtering. This does not permit network request coming from unwanted sources. All these features amplify the security of your network but it can be further improved.

Changing the default administrator passwords (for surfing anonymously) including usernames is one of the basic things you can do to have a computer security. Most hackers know the default logins of various equipments so changing this information adds security to your network. Turning on the WEP and WPA Encryption for your wireless connection helps too. Encryption further scrambles information and messages that are sent via wireless networks so intercepting and deciphering them will be prevented. The stronger encryption you have, the better security.

When configuring a wireless security in your network to protect your computer, try to change the default SSID of your routers and access points. SSID is the network name provided by the manufacturer and this is usually the same. Even though knowing the SSID does not allow hackers to hack into your system, configuring your own SSID makes your network less prone to interception. Disabling SSID broadcast is a step in line with enhancing security. SSID broadcast is a feature commonly used in businesses but in home networks, it is not really needed.

Avoid connecting to open Wi-Fi networks because it raises security risks on your computer network. Most computers now have a setting which automatically enables connection without the need of notification to the user. Try to check this and disable it if it’s present in the setting. The positions of access points or routers also play a part in wireless computer security. Wireless signals often reach outside the house to the streets and these can be detected. Try to place the router or access point in closed area that is far from windows and open spaces. An ideal location would be the center of the house. This does not really prevent wireless signals from going out but leakage is definitely minimized. As earlier mentioned, total “network privacy” isn’t possible yet but you can get a better shot at it by having a wireless computer security.
