In our modern world, Ethernet and TCP/IP have become the de facto standards in most mission-critical control and monitoring applications, largely due to the design of these protocol suites around the Open System Interconnect (OSI) model. However, the freedom and flexibility of being built around such an open system philosophy, while playing a large part in the success of Ethernet, also allows for many vulnerabilities which can be exploited by attackers.
