Cybersecurity

Cybersecurity is one of the most important roles in the tech industry. The global cybersecurity market is projected to grow from almost $218 billion USD in 2021 to more than $345 billion by 2026. Here’s a bird’s-eye view of some the role’s mission-critical skills:

Skill Spotlight:
Cryptography

Definition: The science of creating and implementing algorithms that secure data during communication and transactions.

Key Competencies: Understanding of cryptosystems, cryptanalysis, and the basic principles of symmetric and asymmetric key encryption

Assessment Areas: Analytical Skills, Steam Cyphers, Block Ciphers, Message Integrity, Hash Functions, and more

Skill Spotlight:
Kubernetes
