An Introduction to Security Chap 8 Wireless Network Security Wireless technology / WIFI is a fairly common buzz word and is widely used throughout the world. We currently have just about every piece of technology enabled for wireless communications from our laptops, phones to our automobiles; it’s hard to believe that origins of WIFI technology have only been around since 1985, when the FCC released the use of the ISM band for unlicensed use. Since 1997 the IEEE 802.11 standard has been available to the public and has gone through major changes with the updates in technology and understanding of the bandwidth. As of 2009 most wireless networks use the 802.11n standard that is built into the wireless routers and access points, this system…show more content…
The intention of WEP is to provide data confidentiality that was comparable with the security of a traditional wired network. WEP is widely used and has been the first type of security chosen by most who set up home routers and personal networks. WEP security is at best a low security and has been demonstrated to have numerous flaws, and has since been replaced by WPA and WPA2. The WPA protocol implements much of the IEEE 802.11i standard. Specifically, the Temporal Key Integrity Protocol (TKIP), was adopted for WPA. WEP used a 40-bit or 104-bit encryption key that must be manually entered on wireless access points and devices and does not change. TKIP employs a per-packet key, meaning that it dynamically generates a new 128-bit key for each packet and thus prevents the types of attacks that compromised WEP. WPA2 has replaced WPA. WPA2, which requires testing and certification by the Wi-Fi Alliance, implements the mandatory elements of IEEE 802.11i. In particular, it introduces CCMP (Counter Cipher Mode with Block Chaining Message Authentication Protocol), a new AES (Advanced Encryption Standard) -based encryption mode with strong security. Certification began in September, 2004; from March 13, 2006, WPA2 certification is mandatory for all new devices to bear the Wi-Fi
