What does the acronym LEAP stand for in network security?

  1. Lightweight Extended Authentication Protocol

  2. Lightweight Encryption and Authentication Protocol

  3. Lightweight Extensible Authentication Protocol

  4. Lightweight Enterprise Authentication Protocol

The correct answer is: Lightweight Extensible Authentication Protocol

The acronym LEAP in network security stands for Lightweight Extensible Authentication Protocol. This protocol was developed by Cisco for providing wireless LAN security. LEAP enhances authentication for users by utilizing dynamic challenges and EAP (Extensible Authentication Protocol) methods, allowing for secure communications over a wireless network. In the context of wireless security, its extensibility means that it can support various different authentication mechanisms, adapting to different environments and requirements. This capability makes LEAP a versatile protocol particularly useful in enterprise environments where secure user authentication is crucial. Other options reflect variations of authentication and encryption protocols but do not accurately capture the established terminology used within the industry, which is why LEAP is specifically associated with the term "Lightweight Extensible Authentication Protocol."
