Wireless Technology
Wireless technology has created a new influx of networks within our organizations. This has introduced many new challenges as well as opportunities for our users. For example, Users may want to use their laptop while traveling or working on a sales presentation in a conference room, users now have access to distribute computing solutions (such as Thin Clients), and users are becoming more mobile by using more wireless devices such as PDAs, mobile phones, smartphones and wireless headsets instead of traditional computing devices such as desktops and laptops.
Wireless technology has also provided new security concerns that must be addressed in the organization’s wireless network architecture. One of the key concerns is the problem of electromagnetic interference (EMI). EMI is a concern when two or more wireless devices are operating in proximity to one another. If a new wireless device is operating nearby an existing one, this may cause degradation of performance and possibly even damage to the existing device. The most common form of EMI can be attributed to the use of wireless devices in enterprise environments. An EMI issue on the wireless side is often the cause of poor performance and increased latency in the wired network. This can also be a major concern with virtual private networks, as high-frequency radiation waves (termed “white space radiation”) can exist in this environment.
How to Design Architecture for Enterprise Wireless Security?
Wireless networks are becoming very common in the enterprise, with many devices utilizing it as a primary communication method. Although these networks provide convenience and enhanced productivity, they also provide new opportunities for abuse and breaches of security. This is especially true when wireless devices are in proximity to people or computers that run on the traditional wired network. As such, organizations must be equipped with robust security controls to protect their wireless environment from potential threats and intruders. In order for effective enterprise defense strategies to be put in place, it’s important that we have a solid understanding of how wireless technologies interact with the wired network environment. In this article, we’ll discuss the similarities and differences between the two network architectures and break down the wireless security concerns that must be addressed in order to protect your wired network resources.
