As such, the security implications of the known WPA2 vulnerabilities are limited almost entirely to enterprise level networks and deserve little to no practical consideration in regard to home network security. However, TKIP is still preserved in WPA2 as a fallback system and for interoperability with WPA.Д¬urrently, the primary security vulnerability to the actual WPA2 system is an obscure one (and requires the attacker to already have access to the secured Wi-Fi network in order to gain access to certain keys and then perpetuate an attack against other devices on the network).

#WIFI SECURITY WEP VS WPA CODE#

One of the most significant changes between WPA and WPA2 is the mandatory use of AES algorithms and the introduction of CCMP (Counter Cipher Mode with Block Chaining Message Authentication Code Protocol) as a replacement for TKIP. WPA has, as of 2006, been officially superseded by WPA2. Interestingly, the process by which WPA is usually breached is not a direct attack on the WPA protocol (although such attacks have been successfully demonstrated), but by attacks on a supplementary system that was rolled out with WPA-Wi-Fi Protected Setup (WPS)-which was designed to make it easy to link devices to modern access points. WPA, like its predecessor WEP, has been shown via both proof-of-concept and applied public demonstrations to be vulnerable to intrusion. As such, it had to recycle certain elements used in the WEP system which, ultimately, were also exploited.

TKIP, a core component of WPA, was designed to be easily rolled out via firmware upgrades onto existing WEP-enabled devices. The TKIP encryption standard was later superseded by Advanced Encryption Standard (AES).Дespite what a significant improvement WPA was over WEP, the ghost of WEP haunted WPA. TKIP employs a per-packet key system that was radically more secure than the fixed key system used byВ WEP. Some of the significant changes implemented with WPA included message integrity checks (to determine if an attacker had captured or altered packets passed between the access point and client) and the Temporal Key Integrity Protocol (TKIP). The keys used by WPA are 256-bit, a significant increase over the 64-bit and 128-bit keys used in the WEP system.

WPA was formally adopted in 2003, a year before WEP was officially retired.В The most common WPA configuration is WPA-PSK (Pre-Shared Key). Wi-Fi Protected Access (WPA) was the Wi-Fi AllianceвЂ™s direct response and replacement to the increasingly apparent vulnerabilities of the WEP standard. The Wi-Fi Alliance officially retired WEP in 2004. Systems that rely on WEP should be upgraded or, if security upgrades are not an option, replaced.

As early as 2001, proof-of-concept exploits were floating around, and by 2005, the FBI gave a public demonstration (in an effort to increase awareness of WEPвЂ™s weaknesses) where they cracked WEP passwords in minutes using freely available software.Дespite various improvements, work-arounds, and other attempts to shore up the WEP system, it remains highly vulnerable. As computing power increased, it became easier and easier to exploit those flaws. A stroll through the history of Wi-Fi security serves to highlight both whatвЂ™s out there right now and why you should avoid older standards.Дespite revisions to the protocol and an increased key size, over time numerous security flaws were discovered in the WEP standard. Since the late 1990s, Wi-Fi security protocols have undergone multiple upgrades, with outright deprecation of older protocols and significant revision to newer protocols. WEP, WPA, and WPA2: Wi-Fi Security Through the Ages Understanding the differences between security protocols and implementing the most advanced one your router can support (or upgrading it if it canвЂ™t support current gen secure standards) is the difference between offering someone easy access to your home network and not. ItвЂ™s your network, itвЂ™s your data, and if someone hijacks your network for their illegal hijinks, itвЂ™ll be your door the police come knocking on. As is the case with all security standards, increasing computer power and exposed vulnerabilities have rendered older Wi-Fi standards at risk. What does it matter what the little acronym next to the security protocolВ you chose was? As it turns out, it matters a whole lot. You did what you were told to do, you logged into your router after you purchased it and plugged it in for the first time, and set a password. Read on as we highlight the differences between protocolsВ like WEP, WPA, and WPA2-and why it matters which acronym you slap on your home Wi-Fi network. Even if you know you need to secure your Wi-Fi network (and have already done so), you probably find all the security protocolВ acronyms a little bit puzzling.
