Wi-Fi Protected Access (WPA) was the Wi-Fi Alliance’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 WEP’s weaknesses) where they cracked WEP passwords in minutes using freely available software.ĭespite 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 what’s out there right now and why you should avoid older standards.ĭespite 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 can’t support current gen secure standards) is the difference between offering someone easy access to your home network and not. It’s your network, it’s your data, and if someone hijacks your network for their illegal hijinks, it’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 protocol 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 protocols like WEP, WPA, and WPA2-and why it matters which acronym you slap on your home Wi-Fi network.

There was no real skullduggery required.Īs if all of this weren't bad enough, WEP has serious, unfixable cryptographic weaknesses which can be exploited to crack any WEP network in minutes.Even if you know you need to secure your Wi-Fi network (and have already done so), you probably find all the security protocol acronyms a little bit puzzling. Since all traffic was encrypted and decrypted with the same PSK, Eve at the coffee shop could (and all too frequently, did) easily intercept and read any traffic Bob sent out to the Internet. And even if you handwaved away the weak encryption, you were still vulnerable to sniffing from anyone else joined to the same network. While it was nice that people were actually using WEP, this early security protocol was still pretty terrible-for one thing, it used deliberately-weak RC4 encryption, because the US Government was still treating encryption algorithms as "weapons" which couldn't be exported overseas. Beginning with this shift from numbers to passwords, WEP started seeing much more heavy usage. So while WEP really still worked on raw 40-bit or 104-bit numbers, you could at least share those numbers in ways where actual humans wouldn't immediately revolt with torches and pitchforks.

Later revisions of WEP offered the ability to automatically hash a human-readable password of arbitrary length into those 10- or 26-digit hexadecimal codes in a way that was consistent between the clients and the routers.

Source unclear, GNU Free Documentation License. Ethernet back then was largely connected with a hub rather than a switch, and anybody with a technical bent could (and frequently did) watch everything from passwords to Web traffic to emails wing across the network without a care. In the mid-to-late 1990s, any given machine could "sniff" (read "traffic not destined for it") any other given machine's traffic at will even on wired networks. Swaths of the Internet today may be built upon "back in my day" ranting, but those of you in your 20s or early 30s may genuinely not remember or realize how bad things used to be. Ars took a deep look at what's on the horizon last fall, but readers seemed to have a clear request in response-the time had come to specifically discuss the new Wi-Fi security protocol, WPA3.īefore anyone can understand WPA3, it's helpful to take a look at what came before it during The Dark Ages (of Internet)-a time with no Wi-Fi and unswitched networks. Thanks to upcoming developments in Wi-Fi, all of us connectivity-heads out there can look forward to getting familiar with new 802.11 protocols in the near future.
