CompTIA Security+, Part 8 of 9: Cryptography and PKI

LearnNow Online
Updated Sep 10, 2019

Course description

This course discusses Cryptography, symmetric and asymmetric algorithms, public key cryptography and Key Management. Next it covers hashing, steganography and how to manage Public Key infrastructure as well as digital certificates. Finally, it will go into detail around SSL and TLS, SSH and Virtual Private Networks for the SY0-501 Exam.

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

• Basic familiarity with computer networks, administration, and security is helpful (But, all required information will be covered during the course) • Completion of the CompTIA A+ and Network+ certifications (Helpful, but not required)
