Document Summary
Some of the key factors contributing to the higher security risk of wireless networks compared to wired networks include: Wireless networking typically involves broadcast communications, which is far more susceptible to eavesdropping and jamming than wired networks. Wireless networks are also more vulnerable to active attacks that exploit vulnerabilities in communications protocols. Wireless devices are far more portable and mobile than wired devices. The mobility results in a number of risks. Some wireless devices, such as smartphones and tablets, have sophisticated operating systems, but limited memory and processing resources with which to counter threats, including denial of service and malware. Some wireless devices, such as sensors and robots, may be left unattended in remote and/or hostile locations. This greatly increases their vulnerability to physical attacks. ** figure 18. 1 displays wireless networking components ** ** elements of a wireless network in slides (2 slides) ** Company wireless lans in close proximity may create overlapping transmission ranges.
