Really,we were so happy to meet the the speaker invited by Prof Dr Hanan who is one of the PHD candidate students to share with us his knowledge about the VPN. Mr Khalid started his talk by asking us unexpected questions about VPN. Although we tried our best but,could;t so sophisticated as he was.Then, he deeply explained and discussed the introduction,the function and the idea behind VPN. I can remember one of the definitions he gave to VPN"is a secure way of connecting to a private Local Area Network at a remote location, using the Internet or any insecure public network to transport the network data packets privately, using encryption. The VPN uses authentication to deny access to unauthorized users, and encryption to prevent unauthorized users from reading the private network packets. The VPN can be used to send any kind of network traffic securely, including voice, video or data."In addition, VPNs are frequently used by remote workers or companies with remote offices to share private data and network resources. VPNs may also allow users to bypass regional internet restrictions such as firewalls, and web filtering, by "tunneling" the network connection to a different region.
This the real simulation for VPN:
