CISSP cryptography training: PKI, digital certificates

In this CISSP Essentials Security School video presentation, Shon Harris discusses two core tenants of the cryptography domain: public key infrastructure and the use of digital certificates.

The Certified Information Systems Security Professional (CISSP) cryptography domain within the Common Body of Knowledge (CBK) covers not only keys and algorithms, but also two other core foundational elements of cryptography: public key infrastructures (PKIs) and digital certificates.

In this special multimedia presentation from SearchSecurity's CISSP Essentials Security School, expert CISSP exam trainer Shon Harris, CEO and founder of Logical Security, offers a comprehensive overview of these two topics, as well as other components of the cryptography section of the CBK.

Harris begins by outlining what a PKI is, what it does, where one is used and why PKIs are so critical to maintaining information security. She takes a deep dive into the different components of a PKI, including registration authorities, certificate authorities and digital certificates.

The presentation continues with an outline of how a PKI works and how different components communicate within the infrastructure. Harris also discusses hierarchies, PKI trust and the SSL protocol and its dependence on PKI. Harris concludes with a brief recap of the entire cryptography domain.

Watch the video

This multimedia presentation features not only seminar-style instruction, but also interactive components students can use to reinforce the most critical topics within the domain. Throughout the video, there are sections where students must pause to explore additional domain concepts. The volume can be adjusted on the lower left-hand corner of the video screen; controls to go back to view previous slides or skip ahead can be found on the lower right-hand corner of the video screen.
