The 7 Layers of the OSI Model Last updated: March 03‚ 2008 The OSI‚ or Open System Interconnection‚ model defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next‚ starting at the application layer in one station and proceeding to the bottom layer‚ over the channel to the next station and back up the hierarchy. |Application |This layer supports application and end-user processes.

A Glance at the Session Layer of the OSI Model Throughout the history of networking‚ one model has stood the test of time for providing not only insight‚ but also a foundation by which all networking systems utilize in some form or fashion. The seven layers of the OSI model‚ which stands for Open System Interconnect‚ are: Application‚ Presentation‚ Session‚ Transport‚ Network‚ Data link‚ and Physical. These layers are the framework for networking‚ because they represent the roadmap‚ rules‚ and

target protocols to exploit are the Address Resolution Protocol (ARP)‚ and the Domain Name System (DNS). Steps have been taken to make these protocols more secure in order to prevent MitM attacks. Furthermore‚ the Transport Layer Security (TLS) (and its predecessor‚ Secure Sockets Layer (SSL)) mitigate the risk from MitM attacks over the internet. One of the more targeted protocols to exploit is the Address Resolution Protocol (ARP). This protocol converts
