Wi-Fi Protected Access

WIRELESS NETWORK SECURITY – HOW SECURE IS IT? by Chris Bradley ITT Technical Institute Information Systems Security student November 23, 2010 Dr. French: This report on “Wireless Network Security” is submitted in accordance with your assignment for November 23, 2010. Sincerely, Chris Bradley ABSTRACT For this project, I asked the question “is wireless network protection truly safe?” My literature search led me to conclude that, if consumers use the most up-to-date

are spending on WLAN because it has become a mission-critical component of the corporate network. One of the main benefit that WLAN offers is the convenience, it allows the home and corporate users to access network resources from anywhere without any cable installation. It provides a non-stop access to business systems in public places as well as in areas where it is difficult to install cables like conference rooms, warehouses and manufacturing floors. As it provides mobility so the companies deploying

security at TJX to prevent future breaches. The network wireless system should be upgraded to Wi-Fi Protected Access 2, WPA2, from WEP. WPA2 provides the most secure protocol that is available on a wireless network. WPA2 uses Advanced Encryption Standard to encrypt all the data when the data is in motion. AES encryption takes a hacker months, even years to break. If the company wants customers to have free Wi-Fi then have two separate networks in which one is has a network password and other just requires

divided into wired and wireless. Wi-Fi - a trademark of Wi-Fi Alliance for wireless networks based on the standard IEEE 802.11. The acronym Wi-Fi (from the Wireless Fidelity, which can be literally translated as "the quality of the wireless") is currently developing as a family of standards for the transmission of digital data radio streams. It is still often hears that the wireless network is not secure compared to wired solutions. At the present stage of Wi-Fi technology‘s development that is not

Any WEP reliant devices should be upgraded or replaced. WEP uses 64-bit and 128-bit keys. Wi-Fi Protected Access (WPA) was the “replacement” for the WEP security standard. Although many changes were made, it still shared some WEP components and wound up being exploited by attacks on Wi-Fi Protected Setup (WPS), which allows devices to link to access points easier. WPA uses 256-bit keys. Wi-Fi Protected Access II (WPA2) uses the Advanced

was part of the original 802.11 standard. It was suppose to provide data confidentiality comparable to that of wired networks. WEP has many well-known security flaws, is difficult to configure, and is easily broken. However, in 2003, the Wi-fi Protected Access (WPA) security protocol has replaced the WEP standard. The

It access in limited area like schools, colleges, organizations, offices, and computers labs etc. This helps the clients to access even while roaming near about that area and still they remain connected with network. In the industries or complexes, wireless LANs helps the customers to access to the internet and they can access without any installation, giving these users wireless access to the full resources and services to industries, colleges

Part 1: Question 1 Standard Definition Algorithm Suggested Use WEP A wireless protocol that is intended to deliver the privacy comparable to that of a wired network. RC4 No longer used unless it is for lessons in hacking. Big security flaws and easy to hack. WPA This protocol offers more data encryption than WEP and also offers user authentication. RC4 with TKIP This is used with older devices. But these may still need an update through firmware so they will be compliant. WPA2 This protocol offers
