Certified Information Systems Security Professional, Part 4 of 9: Cryptography and Network Topologies

Course description

This course covers symmetric and asymmetric cryptography and their history will be covered along with topics like Public key infrastructure, and various attacks. Also network and communication security will be discussed with topics inluding: network topologies, cabling and finally end with looking at network solutions. 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 4 of a 9 part series.
