Just to follow-up on the comments from Jim and Valdis.  Obsoletely  
there can be valid business reasons for unencrypted protocols  
particularly for research and education.  The key point here is that  
we ask for these to be handled by an exception process.  Rather than  
allowing FTP by default for example we ask that departments contact  
the security group to discuss the risk in granting the exception.    
In addition to solving individual business or technical needs as  
Valdis points out to force the change is a huge communications  
effort.  If you create the policy but do not successfully communicate  
the policy requirements your policy will not be effective.  You may  
also have to target communications down to the individual user and  
system owner so that you do not break critical business needs.     
Depending on your environment this may be a challenge requiring that  
you build new communication mechanisms.
