A wireless network is a computer network that allows computerized devices to
communicate without needing a physical medium connection like the cables (Vela,
Kraus, Friedman, Irizarry & Suman, 2018). A wireless access point (WAPs)
establishes wireless networks. WAP can be described as a hardware device that allows
computerized devices and other Wi-Fi devices to connect to the network. WAPs are
connected to a wired network through a router. WAPs include antennae and radio
transmitters that facilitate the connection between the computer devices in the
network. WAPs mostly use Wi-Fi standards. The security in the network is very
important. The main wireless security concepts I have learned from the video are
explained below:
Wired Equivalent Privacy (WEP)- WEP is a security protocol that is in place to
ensure that there are privacy and security in the wireless network. WEP was released
in 1997, with the intention of providing wireless communication with the same level
of privacy and security as in wired communication (Mohapatra & Prakash, 2010).
WEP has some weaknesses: weak encryption, no authentication, and shared static
keys. This makes it weak, making it easier to be cracked by attackers.
Wi-Fi Protected Access (WPA)- due to the weaknesses experienced in wired
equivalent privacy, there was a need for a more secure protocol. WPA is a security
protocol used to secure computerized devices with internet connections (Kwon &
Choi, 2020). WPA uses a dynamic encryption key and strong encryption. It also
includes authentication. All these features make it the best security choice when
compared to WEP.

Hi Kathic,
You have some great points. I would also like to add few more points on this.
In order to provide security and to transmit data, 802.11 introduced the Wired
Equivalent Privacy (WEP) protocol, thus trying to bring the security level of
wireless systems similar to a wired network. Provides security by encrypting
data over radio frequency waves, so its protected as its transmitted from end
point to end point (Posey, 2003). It works by using secret keys or codes to
encrypt data and both access point and client must know the codes in order for
it to function. However, there have been many flaws with WEP’s intended
security goals with as found by a group of researchers from the University of
California at Berkeley and Zero-Knowledge (Mehta, 2001). These flaws
