What we know today as wireless, or Wi-Fi networking has evolved from the IEEE 802.11 publication of 1997. This standard called for wireless transmission rates of 1 and 2 megabits per second (Mbits/s) to be transmitted on the 2.4Ghz band. In 1999 the 802.11b amendment was published. This amendment called for wireless transmission speeds with a maximum transmission rate of 11 Mbits/s (Wikipedia, n.d.). This was the first version of wireless networking adopted by mainstream users and the business community.
Wireless networking gained more momentum and speed in 2003 when 802.11g was ratified. The G specification calls for maximum speeds of up to 54Mbits/s and is backwards compatible with 802.11b (Wikipedia, n.d.). The increasing speeds made wireless even more attractive to users. As a result businesses began to deploy more wireless networks. Today it is estimated that there are nearly110 million wireless notebooks in use (Khalil, 2004). |

In 1996, the Health Insurance Portability and Accountability Act (HIPAA) was enacted to protect health information by establishing transaction standards for the exchange of health information, security standards, and privacy standards for the use and disclosure of individually identifiable health information. Entities directly impacted by this act are health plans, health clearinghouses and healthcare providers (“TLC HIPAA Overview”, n.d.).
Although there are other rules incorporated in HIPAA, the Security Rule has the most direct impact on hospital technology systems including network infrastructure. This rule addresses security measures such as user authentication, access controls, audit trails, controls of external communication links and access, physical security, systems back up, and disaster recovery. With increasingly more information being stored and transmitted electronically, the Security Rule works to identify and regulate these activities (Gue, n.d.). |

During the infancy of the wireless computing age, key defenses and deterrents to wireless attacks were the cost and complexity of methods required to partake in such activities. The current age of easily accessible, inexpensive tools have tilted the balance of price, complexity, and deterrence in favor of the novice wireless attacker. During year 2005, over a billion wireless users are projected (Lauter, 2004). As of this writing, the wireless security discussion is in escalation. This paper is a brief participant of the discussion, and concludes multiple security mechanisms (a hodgepodge, instead of a single solution) provide maximum wireless security. |

The Securities and Insecurities of Wireless Networks Today
Everyone is looking for a way to make things easier and more convenient, especially when it comes to technology. Everything that was once new and revolutionary became old and drab because it was stuck in one place due to wires. When laptop computers became smaller and more portable, the need for wireless connectivity became blatantly obvious. Having a wired connection does not allow us to keep up with the fast-paced society that we live in today. Around the early 1990’s, teams of engineers greatly expanded our options for portable technology. “Wireless technologies are without any doubt shaping the beginning of the new millennium. The principal of computing any time, anywhere, is becoming reality.”
Around 1991, “Wi-Fi” or “Wireless Fidelity” was invented by Vic Hayes of Lucent and Agere Systems in the Netherlands. Its initial design was meant for cashier systems and the first products on the market were called “WaveLAN.” This first attempt at wireless only supported speeds of 1 Mb/s to 2 Mb/s. In the past 15 years, things have definitely come a long way. The speeds have increased dramatically from their initial design and have given the world of wireless technology infinite possibilities. |
