cryptographic tunneling and the osi model –

  • Write a paper consisting of 500-1,000 words (double-spaced) on the security effects of cryptographic tunneling based on an understanding of the OSI (Open Systems Interconnect) model.
  • Review the OSI Simulation in the week 3 lecture.
  • Provide input on the type of cryptographic tunneling protocols (e.g., L2TP, IPSEC, SSL, etc.) which may be used, the layer(s) of the OSI at which each operates, and also recommend how they may be implemented. Cryptographic tunneling is inherent in building any common virtual private network (VPN).


Sunshine Machine Works, who recently expanded its infrastructure, now needs to ensure that any authorized employee can access the intranet. Sales people and management staff frequently travel to remote locations, and often require access to documents stored on the intranet file server.


You are the IT Services manager for Sunshine Machine Works. You are to assess the information presented and provide a response to management on how remote access may be handled for Sunshine Machine Works.

Chief Executive Officer

It’s great that we have expanded and are able to reach out to customers all over the country. With the way things are going, I see real potential for continued success as long as our field assets have the ability to access information here on our local network. I don’t have any problem with any or our people getting access to the resources they need. I just don’t want anything compromised because I don’t want to lose any proprietary information or have any of our customer’s data leaked.

Chief Financial Officer

I am pretty paranoid when it comes to this remote access stuff. I keep hearing about people getting their networks broken in to and the next thing you know their bank accounts have been drained! However, it is apparent that this is an option whose time has come. I hope we are able to keep our data safe.

Gary Thomas

General Manager

We have workers who travel to remote locations and need to access information here on the Intranet. I would rather have our people accessing information over a secure connection than sending them out to who knows where with a laptop or thumbdrive full of our company information. Let’s see if we can solve the problem of remote access and maintain company proprietary information.
