Frequently Asked Questions

Who is this course for?

This course is designed for cybersecurity professionals, IT administrators, network professionals, system administrators, and anyone who needs to understand how digital trust and encryption are established in modern environments. It’s also a useful starting point for learners building foundational knowledge of cryptography and security infrastructure.

Why should I complete this course?

PKI supports many of the technologies organizations rely on to authenticate users, secure communications, and protect sensitive information. Completing this course will help you understand the infrastructure behind digital certificates and encrypted connections, giving you the knowledge to better evaluate and manage security technologies that depend on PKI.

What skills does this course develop?

Upon completing this course, you should be able to:

  • Describe the core components of a Public Key Infrastructure (PKI), including the roles of Certificate Authorities, Registration Authorities, and the Trust Hierarchy (Root vs. Intermediate CAs).
  • Differentiate between asymmetric and symmetric cryptography, explaining how PKI utilizes both to achieve secure, scalable communication.
  • Analyze the lifecycle of an X.509 digital certificate, from the initial Certificate Signing Request (CSR) and issuance to maintenance, renewal, and revocation.
  • Evaluate methods for certificate revocation, comparing the mechanisms, benefits, and limitations of Certificate Revocation Lists (CRLs), the Online Certificate Status Protocol (OCSP), and OCSP Stapling.
  • Explain the phases of the TLS/SSL handshake, detailing how it establishes server identity, negotiates cryptographic parameters, and ensures perfect forward secrecy.

Success from Our Learners

"Cybrary really helped me get up to speed and acquire a baseline level of technical knowledge. It offers a far more comprehensive approach than just learning from a book. It actually shows you how to apply cybersecurity processes in a hands-on way"

Don Gates

Principal Systems Engineer/SAIC

"Cybrary’s SOC Analyst career path was the difference maker, and was instrumental in me landing my new job. I was able to show the employer that I had the right knowledge and the hands-on skills to execute the role."

Cory

Cybersecurity analyst/

"I was able to earn my CISSP certification within 60 days of signing up for Cybrary Insider Pro and got hired as a Security Analyst conducting security assessments and penetration testing within 120 days. This certainly wouldn’t have been possible without the support of the Cybrary mentor community."

Mike

Security Engineer and Pentester/

"Becoming a Cybrary Insider Pro was a total game changer. Cybrary was instrumental in helping me break into cybersecurity, despite having no prior IT experience or security-related degree. Their career paths gave me clear direction, the instructors had real-world experience, and the virtual labs let me gain hands-on skills I could confidently put on my resume and speak to in interviews."

Cassandra

Information Security Analyst/Cisco Systems

"I was able to earn both my Security+ and CySA+ in two months. I give all the credit to Cybrary. I’m also proud to announce I recently accepted a job as a Cyber Systems Engineer at BDO... I always try to debunk the idea that you can't get a job without experience or a degree."

Casey

Cyber Systems Engineer/BDO

"Cybrary has helped me improve my hands-on skills and pass my toughest certification exams, enabling me to achieve 13 advanced certifications and successfully launch my own business. I love the practice tests for certification exams, especially, and appreciate the wide-ranging training options that let me find the best fit for my goals"
