Description: WEP, which stands for Wired Equivalent Privacy, is a security protocol designed for wireless networks that aims to provide a level of security similar to that of wired networks. This protocol was part of the IEEE 802.11 specification and was introduced in 1997. WEP uses encryption techniques to protect information transmitted over Wi-Fi networks, employing the RC4 encryption algorithm. By utilizing encryption keys, WEP attempts to ensure the confidentiality of data as well as the authenticity of users accessing the network. However, despite its intention to offer security, WEP has been criticized for its inherent vulnerabilities, which have been exploited on multiple occasions. Weaknesses in key management and the use of a considered weak encryption algorithm have led to the recommendation to use more secure protocols, such as WPA and WPA2, which offer better protection mechanisms. Despite its limitations, WEP was one of the first attempts to secure wireless networks and laid the groundwork for the development of more robust security standards in the realm of wireless communication.
History: WEP was introduced in 1997 as part of the IEEE 802.11 specification, being one of the first security protocols for wireless networks. Over the years, multiple vulnerabilities were discovered in WEP, leading to its obsolescence in favor of more secure protocols like WPA (Wi-Fi Protected Access) in 2003 and WPA2 in 2004. In 2004, the National Institute of Standards and Technology (NIST) advised against the use of WEP due to its security weaknesses.
Uses: WEP was primarily used in Wi-Fi networks to provide a basic level of security in data transmission. Although its use has significantly decreased, some legacy networks may still employ WEP, although this is not recommended due to its vulnerabilities.
Examples: An example of WEP usage could be a home Wi-Fi network set up in the early years of wireless technology, where users sought to protect their Internet connection, although today it is advised to upgrade to more secure protocols.
