  1. 91.527 - Human Computer Interaction - Fall 2010Class project ByKhang Nguyen Virtual Private Network Design for Remote Access Cambridge - SFO Airport Test Site

  2. Virtual Private Network Access for SFO Airport Lidar System • VPN Concept • VPN Benefit • SSL SonicWall VPN-200 • Case Study – SFO Airport Site • Using VNC (Virtual Network Control) • Conclusion
