Hi,
I can understand your reluctance. I think Skype would've gained the
trust of network admins everywhere if they made it easy to block Skype
but still encrypted everything. That way, people who are very
conservative about what traffic goes out of their networks can block
Skype and the rest can knowingly allow it. At the moment, it is very
difficult to block Skype.
It is the viral nature of Skype which puts me off. It bypasses NAT
devices and even proxy servers. At the moment it cannot pass through a
proxy server which requires a password from the user but I can't see
that being a barrier for very long. A user can install a local proxy
which does not require a password which then authenticates itself to
the corporate proxy. Or they might introduce that functionality into
the Skype client software itself.
If I had to take a decision I would block Skype because I don't know
what comes and goes through Skype. But blocking it isn't very easy as
it can make itself look just like web browsing traffic.
On a Windows machine, even if you shutdown Skype it is still running in
the background acting as a "super node" relaying calls for people who
are behind very restrictive networks. That can use a lot of bandwidth
and processing power. Although they are no known viruses/backdoors for
Skype, as it increases in popularity it is only a matter of time before
some flaw is discovered.
I will happily use Skype on my PC at home and my mobile phone when
roaming but I wouldn't trust it in a corporate environment. If Skype
made a corporate version of their product where the network admin can
control who can get onto that "private" Skype network, you have a
winner there for everyone!
cheers,
Chandru
