Hi and welcome.
now in this lecture.
We're going to learn about different types of Wi-Fi protocols.
There are three kinds of wireless security protocols out there.
And those are WEP WPA and WPA2 . Wi-Fi
Protocols are kind of logical to secure your Wi-Fi network but it is sometimes a bit puzzling to understand
which encryption protocol to implement
with all the acronyms. So now I will try to explain the difference among the encryption standard like WEP WPA
etc. so you can understand which your work best Wi-Fi security algorithms have been through many
changes and upgrade since the 1990s to become the more secure and effective different types of wireless
security protocols were developed for homework wireless network protection. The wireless security protocol
are WEP WPA and WPA2 serving the same purpose but being different at the same time.
Not only do the protocols prevent unwanted parties from connecting to your wireless network but also
wireless security protocols encrypt your private data sent over the airwaves.
No matter how protected an encrypted wireless security cannot keep up in safety with wired network. The later
at their most basic level transmit data between two points A and B connected by a network cable.
To send data from A to B wireless network broadcasts it within their range in every direction to every
connected device that happened to be listening.
Okay let's have a closer look at WEP WPA and WPA2. wired equivalent privacy or WEP was developed for wireless
networks and approved as a Wi-Fi secured standard in September 1999 WEP was aim to offer
the same security level as a wired network do.
However there are a bunch of well-known security issues in WEP which is also easy to break and hard
to configure.
Despite all the work that has been done to improve the WEP system that is still is a highly venerable
solution. Systems
that's really on these protocols should be either upgraded or replaced in case securely upgraded is
not possible.
WEP was officially abandoned by Wi-Fi Alliance in 2004 Wi-Fi protected access or WPA for the time
the 802.11i wireless security standard was in development.
WPA was used as a temporary security enhancement for WEP. One year before WEP was officially abandoned
and WPA was formally adopted.
Most modern WPA application use a Pre shared key or PSK most often referred to as WPA personal and the temporal
key integrated protocol or TKIP for encryption. WPA enterprise use an authentication server for case
and certificates generation WPA was a significant enforcement over WEP but as the core competence were
made so they could be rolled out through firmware upgrades on WEP Enable devices they steal relayed on to exploited
element WPA just like WEP after being put through proof of concept and applied public demonstration
turned out to be pretty vulnerable intrusion the attacks that post the most treated to the protocol
ware however not the direct ones but those that are made on Wi-Fi protected set-up or WPS.
Auxiliary system developed to simplify the linking of the device to Modern access point. Now
Wi-Fi protected access version 2 or WPA2. The 802.11i wireless security standard
based protocol was introduced in 2004.
The most important improvement of WPA2 over WPA was use of the advanced encryption standard
or AES for encryption AES is approved by the US government for encrypting the information classified
as top secret. So it must be good enough to protect home network. At this time the main vulnerability
to a WPA2 system is when the attacker already has access to a secure Wi-Fi network and can
gain access to certain key to perform an attack on the other devices on the network.
This being said the security suggestion for the known WPA2 vulnerability are mostly significant
to their networks of enterprise level and not really relevant for small home networks.
Unfortunately the possibility of the attacks via the Wi-Fi Protected setup WPS is still high the
current WPA2 capable access point which is the issue with WPA also and even to breaking into a WPA
WPA2 secured network through these whole will take anywhere around 2 hours to 14 hours.
And it is still a real security issue and WPA should be visible and it would be good if the access
point firmware could be reset to distribution not supporting WPS to entirely execute this attack
Vector.
Now theWi-Fi protected setup or WPS. Wi-Fi protected setup is a network security slandered to create
a secure wireless home network.
The goal of the protocol is to allow home users who know little of wireless security and may be intimidated
by the available security options to setup Wi-Fi protected access. As well as making it is easy
to add a new device to existing network without entreating a long past presses. A major security flaw
was relived in December 2011 that effects wireless routers with the WPS pin features which most recent
models have been enable by default.
The flaw allows a remote attacker to recover the WPS pin in a few hours with a brute-force attack.
The users have been urged to turn off the WPS pin features although this not be possible on some router models.
So what do you think.
What is the best protocol forWi-Fi security.
I hope you understand which protocol work best for Wi-Fi security.
That's all for this lecture.
So seeing the next one. Bye.
