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

"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"
