Layers 5 & 6

Two seemingly unimportant layers were intensely discussed today. Layers 5 & 6 get a lot of flack and some even say that they are unimportant. However, encryption and sessions lie within these layers. In a world of security, encryption is a very important aspect. Encryption is integrated into secure wireless, VPNs, and certificates. Sessions are also an important item to remember especially when pondering timeouts on web sessions like Facebook and Gmail. How does that login stay active? I would say that a session is established and that the sessions ends when the user either presses the logout button, the browser is closed or a inactivity timer fires. #ITEC485 #osimodel #networking #security
