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

Course description

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 is part of a series covering the ISC(2) Certified Information Systems Security Professional (CISSP).

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This series assumes a good understanding of enterprise networking and networking security. This is part 5 of a 9 part series.
