Description: Wired Equivalent Privacy (WEP) is a security protocol designed to protect wireless local area networks (WLANs) by providing a level of security and privacy comparable to that of wired networks. WEP uses encryption techniques to secure data transmission between devices on a wireless network, allowing sensitive information to remain safe from unauthorized access. This protocol relies on the use of encryption keys shared among devices connected to the network, enabling user authentication and protecting the integrity of transmitted data. However, despite its intention to offer security, WEP has faced criticism due to inherent vulnerabilities that have led to its obsolescence in favor of more secure protocols like WPA and WPA2. Despite its limitations, WEP was an important step in the evolution of wireless network security, marking the beginning of the need to protect communications in environments where mobility and connectivity are essential.
History: WEP was introduced in 1997 as part of the IEEE 802.11 standard for wireless networks. Its development was driven by the need to secure communications in an environment that was beginning to adopt wireless technology. However, as technology advanced, multiple vulnerabilities in WEP were discovered, leading to its eventual replacement by more robust protocols like WPA (Wi-Fi Protected Access) in 2003 and WPA2 in 2004.
Uses: WEP was primarily used in home networks and small businesses to protect information transmitted over wireless connections. Although its use has significantly declined due to security weaknesses, it was once a popular solution for data protection in various environments where mobility was a key factor.
Examples: An example of WEP usage can be found in first-generation routers that offered this security option for wireless networks. Many devices of that era, such as certain models from Linksys and Netgear, allowed users to configure WEP to protect their home network.
