Wireless Network Tutorial

Wireless security issues are a personal and institutional concern. With the proliferation of identity theft, individuals and organizations are well advised to take wireless security issues seriously and to institute precautions to eliminate any potential malicious damage. With modern business practice requiring data system dependency, it is prudent for organizations to protect the integrity of wireless infrastructure.

A first and foremost wireless security issue is access and authorization. With the plethora of advanced programs and techniques, individuals with the right equipment and malicious intent can breach individual and organizational privacy leaving parties exposed to stolen passwords, sensitive commercial information and identity theft. Scanning for open nodes and using packet sniffers to monitor traffic can take place in public cafes, airports, libraries or personal and commercial settings. It is important that appropriate measures be taken to monitor network access and lockdown connections.

Using WPA/WEP technology to encrypt traffic and scramble it so that unauthorized third parties can't make sense of it is a prudent measure. WPA or more specifically, WPA2 is the preferred way to maintain encryption and password access control. Any private services should still make use of SSL encryption. WPA can be used in personal or institutional mode. Institutional mode is more complex to setup and establish because it requires the implementation of a RADIUS server and software must be installed on individual terminals. The advantage of the institutional version is that it permits the issuing of individual usernames and passwords. Organizations that do not setup the institutional version can be exposed to wireless network security problems that occur through the use of unauthorized password access and use.

Remote access points also need to be carefully kept in check to prevent wireless security problems. Web interfaces or remote management setups require the assessment and establishment of protocols. Any passwords should be changed frequently as a security precaution. Organizations should have established policies to deal with this as part of their information architecture mandate to protect digital assets and minimize potential problems with wireless security.

Network monitoring software can be used effectively to combat wireless security issues and concerns. This is addressed in the article provided on this site titled 'Wirelsss Network Security Software'. Software permits locking down individual terminals to prevent bandwidth access and unauthorized use. In commercial situations, advanced monitoring and reporting tools allow managers to monitor network traffic, terminal access and grant privileges to end users. This software is a great way to identify and manage problems with wireless security.
