GT explains: Difference between WEP, WPA and WPA2 and which one is the most secure
The first rule for Wi-Fi networks is that you don't leave your network unprotected. The second rule for Wi-Fi networks is that you don't connect to unprotected Wi-Fi (not without a VPN at least). And yes, don't hesitate to talk about it.
WEP, WPA, and WPA2 are three different types of security protocols. When you set up your router and add a password, one of these formats was selected. Does it matter which one you choose? If safety is more important to you than the average Joe, this is it.
Encryption for everyone
WEP, WPA and WPA2 have different encryption levels. Basically, the format in which you save a password determines how strong it is. Or how easy / hard it will be for someone to crack it.
Wired Equivalent Privacy (WEP) is the most widely used protocol. This is also the default setting for most routers. That alone should be enough for the skeptic in you to raise an eyebrow. Nothing standard is ever good, is it?
WEP was officially declared as a standard in September 1999. It started with 64-bit encryption, then moved to 128 and now supports 256-bit too. However, many devices are still stuck at 128 bits.
The skeptic in you was right, by the way. WEP is known to be easy to crack. All you need is free software. The Wi-Fi Alliance discontinued WEP back in 2004, but will continue to support it due to backward-compatible devices and the long lifespan of corporate electronics.
Conclusion? Do not use WEP.
Not much better
Wi-Fi Protected Access (WPA) is what replaces WEP. It was an upgrade to WEP designed as a firmware upgrade for current devices. Because of this, it depended on a lot of ancient technology.
All in all, WPA is better than WEP, but not that much.
How do you like me now
Wi-Fi Protected Access II (WPA2) is the latest and greatest in Wi-Fi security. I'm sure you sensed a trend by now. Every upgrade is better than the previous one. WPA2 was added to the official list in 2006 and has been actively developed since then.
WPA2 uses 256-bit AES algorithms for encryption (industry standard), which makes it much more secure than the previous ones.
Because of the way WPA2 works, anyone trying to hack into a network will need physical access to one of the devices. And even then, it can take hours.
Unfortunately, since WPA2 is based on WPA, which in turn is based on WEP, it also suffers from some of the weaknesses of our retired friends. Thanks to constant updates, these doors are now screwed a little more tightly.
Which one should i choose?
It is now clear that you should choose WPA2. It is the lesser of the three evils. Yes, it can be hacked, but it can also be anything. The reason we use stronger protocols is because people make it harder to hack into. So WPA2 is definitely the way to go. It increases the hacking time from a few minutes with free software to hours or days or professional hacking. Basically, this blocks most of the hackers out there.
And if a person is committed enough to spend hours or days hacking into your system (hello NSA didn't see you there, keep going) they will find a way.
Also a hacker who spends 12 hours with you? Boy you have to be special
