Virtual Private Networks

 

Virtual private networks (VPNs) are used to establish a secure remote connection, and most encrypt their traffic to make it secure. Imagine that you are working for a company that has asked you to examine the various types of encryption and to choose the one you would recommend.

• Discuss whether VPNs are totally secure. If they are not secure, what additional features would make them so?
• Explain why you would use a VPN to establish a remote connection with the hypothetical company you are working for.
  • What type of encryption (encryption method, number of bits) would you recommend, and why?
  • Which standard for encryption would you rely on, and why?
• In addition to a VPN, describe how you can make the connection more secure and ensure that it is the employee who is logging in to your network.
