Skype

Skype (www.skype.com) is a free Internet telephony product that uses peer‑to‑peer (P2P) networking protocols. This allows users to make free internet‑based phone calls. This is a good tool to use on a personal basis at home but is not allowed and won't work on the UVU network.
 
OIT Security prohibits and blocks the use of Skype on the UVU network for three main reasons:
  1. Skype uses excessive network resources.
  2. The Skype User Agreement makes the user agree to provide services to Skype for resources owned by the University.  Individual users are not empowered to give such consent.
  3. P2P traffic is prohibited on the UVU network (most often used for illegal file sharing).
 
Instances of Skype on the UVU network have been found to be the highest users of network resources. This is likely because the software can act as a Supernode. From the Skype privacy policy:
"A Supernode is a computer running Skype Software that has been automatically elevated to act as a hub. Supernodes may assist in helping other users to communicate or use the Skype Software efficiently. This may include the ability for your computer to help anonymously and securely facilitate communications between other users of the Skype software who, due to network and firewall constraints, cannot establish direct connections."
Therefore, running Skype means your system can (and probably will) participate in providing Voice over IP (VoIP ‑ internet phone calls) services outside of your direction and control. You are also agreeing to provide services to Skype for resources owned by the University. Individual users are not empowered to give such consent.
 
Summary
 
  1. Skype's End‑User License Agreement (EULA) requires the user to grant use of university network bandwidth by Skype users otherwise unaffiliated with the college, and end users are not authorized to enter into this type of agreement on behalf of the University (i.e., the owner of the resource).
  2. The operation of Skype's relay function is not in compliance with university policy because:
    1. It provides service to third‑party people other than those conducting university businesses.
    2. It exceeds incidental personal use.
  3. Skype persistently alters host firewall settings and increases the probability the computer will be compromised.
  4. Skype uses P2P protocols.
 
For these reasons Skype is not permitted at UVU if you have any questions please feel free to email them to it@uvu.edu.
