               your IM Security protection strategy:
            
            
               -

               -

                     Skype for Business server?
                  
                  
                
               - 
                  
                  
Where and how can security risks and unwanted content enter the Lync or Skype
                     for Business server environment (for example, file transfer, instant message)?

                             | 
                           
                              Note
