Virtual Private Networks

1. What is a site-to-site VPN?
   • A virtual private network (VPN) that links multiple. typically geographically separated networks with a secure connection; sometimes called a "tunnel".
2. What is TCP/IP and what is it used for?
   • Transmission Control Protocol/Internet Protocol is the set of rules that enables communication and data transfer to occur through the internet.
3. What are some popular reasons for using a VPN?
   1. Good for securely linking multiple geographically distant sites into a common network for sharing data.
   2. Excellent security
   3. Easy to use
   4. Easy scalability
   5. System redundancy for business continuity
   6. Flexibility
4. Explain the difference between the three types of VPNs.
   • Intranet-based joins multiple sites together into a secure WAN which wich makes widespread sharing of files easier.
   • Remote access allows most flexibility for many field workers who aren't often in the office environment. It allows them to remotely access the network wherever they are through a secure connection from a laptop or other mobile device.
   • Extranet-based sits in between two or more organizations or offices. It allows each entity to maintain a private intranet while still being able to share data through the VPN they both have access to.
