Certified Information Systems Security Professional, CISSP, Part 5 of 9: Network Protocols and Wireless

This course will discuss protocols and structures of communications transmitted across networks. OSI hierarchy and the devices that manage communications and how to protect them. It will end with ports, services and switches and how they must be secured and network based attacks to be prepared for. This course contains the following lessons:
