While many network managers take security into consideration, the reality is that their primary, day-to-day focus is on another matter entirely: uptime. Information security pros can become valuable partners in fortifying the network, but only if they are fluent in how networks -- and all their various components -- are built and operated. Simply put, you can’t secure what you don’t understand.
In this Security School, based on (ISC)² CISSP training material on Domain 4 of the exam, learn about networking and network security fundamentals, including the OSI model, secure routing methods, partitioning, different types of network-based attacks and more. In his video, expert Adam Gordon dissects each layer of the OSI model -- taking viewers from the application down all the way to the physical layer -- and outlines essential takeaways for infosec pros each step of the way. In his tip, Gordon explores different methods of isolating infrastructure to evade common network attacks.
