I am trying to write a security opinion that may influence policy in the future in the Enterprise-grade network which I work to protect regarding the use of Skype on the networks, and security risks thereof. I have been trying to find recent analyses of Skype from a security standpoint, but I am unable to find more recent analyses (older than 2011 is what I have been finding).
Is anyone able to link me to a more recent analysis of Skype security, or help outline the security risks of Skype such that the security opinion is more complete?
(Security research briefs, whitepapers, etc. are generally what I'm looking for)
