Potential Security Vulnerabilities of a Wireless Network in a Military Healthcare Facility
The adaptation of wireless technology into the healthcare practitioner’s daily activities is changing the face of patient care every day. Doctors can now review any pertinent patient data from digital x-rays as they are taken, lab results as they are coded into the system and live patient vital statistic monitoring from their mobile PDA’s and Tablet PC’s at the point of care. Wireless technology adaptation has other benefits such as lowering long term cost of infrastructure maintenance and upgrades, and allowing for rapid changes to the network infrastructure versus wired technology. (Owens, Tachakra, Banitsas, Istepanian, 2001) As a system administrator in a large military healthcare facility, I am responsible for the security of all systems, network and patient data that is transmitted through that network. To keep up with the advanced implementations of wireless technology, understand the requirements I am bound by and the threats I may have to face, I started this research project for my own benefit as well as to share my findings with my staff. I will review the regulations that govern patient data in its electronic state, review a number of the current threats against a wireless network and recommend a possible wireless structure based on my research and policies that guide me. |

Radio Frequency Interference and its Use as a Weap

Radio frequency is a type of electric current on a wireless network, which emits an electromagnetic field when alternating current is applied to an antenna. Similar to waves that result from a rock thrown into water, radio waves are altered when obstructions appear, and may reflect or scatter for example, depending on their interactions with each other. (Shimonski, 2002) Wave fronts are generated when the waves become reflected. So from a receiver’s perspective, the wave fronts may be in or out of phase with the main signal as they reach the receiver at different times. If the peak of one wave is added to the peak of another, they are in phase and the wave will be amplified. If the peak of one wave comes in contact with the valley of another, they are out of phase, and the wave is eliminated.
Radio Frequency Interference occurs “when a signal radiated by a transmitter is picked up by an electronic device in such a manner that it prevents the clear reception of another and desired signal or causes malfunction of some other electronic device (not simply a radio or television receiver).” (Brock, Fall 1998) RFI can be induced intentionally, or unintentionally. |

Resource Allocation and Cross Layer Control in Wireless Networks Apr 2006
Resource Allocation and Cross Layer Control in Wireless Networks presents abstract models that capture the cross layer interaction from the physical to transport layer in wireless network architectures including cellular, ad-hoc and sensor networks as well as hybrid wireless-wireline. The emphasis in the presentation is on describing the models and the algorithms with application examples that illustrate the range of possible applications. Representative cases are analyzed in full detail to illustrate the applicability of the analysis techniques, while in other cases the results are described without proofs and references to the literature are provided. |
