Which standard is often used to secure wireless networks?

1. WPA2

2. WEP

3. 802.11g

4. TCP

The correct answer is: WPA2

WPA2 (Wi-Fi Protected Access 2) is a security protocol commonly used to secure wireless networks. This standard provides strong encryption and authentication to protect data transmitted over a wireless network, addressing vulnerabilities present in earlier standards such as WEP (Wired Equivalent Privacy). WPA2 uses the Advanced Encryption Standard (AES), which is more robust in securing wireless communications. While WEP is another option associated with wireless security, it is outdated and has several known vulnerabilities that make it inadequate for modern security needs. The 802.11g option refers to a wireless networking standard that specifies the physical layer and media access control for wireless communication but does not include security features by itself. TCP (Transmission Control Protocol) pertains to a transport layer protocol used in the internet protocol suite and is not related to wireless network security. Thus, WPA2 stands out as the widely accepted standard for securing wireless networks due to its comprehensive security capabilities and improvements over previous protocols.
