Course Description

Blockchain is increasingly embedded in the technologies and systems organizations use, creating new security considerations for cybersecurity teams. While blockchain can offer benefits such as distributed recordkeeping and transaction transparency, it also introduces unique risks that security professionals need to understand. Without a foundation in how blockchain works, it can be difficult to recognize vulnerabilities, evaluate threats, or assess the security implications of blockchain-based systems.

This blockchain security training provides an introduction to blockchain technology through a cybersecurity lens. You’ll build an understanding of the technology’s role in modern digital environments and why its architecture and implementation matter to security. Whether your organization uses blockchain directly or relies on services built around it, this course provides a starting point for recognizing blockchain-related security concerns and strengthening your ability to evaluate emerging risks.

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"
