OffSec SEC-100 CyberCore - Security Essentials Training

SEC-100 Security Essentials provides a comprehensive foundation in cybersecurity for learners at the beginning of their careers. Covering a breadth of essential topics across governance and risk frameworks, offensive, defensive, and secure-by-design disciplines. The course also integrates general technical competencies, including scripting, networking, and cloud fundamentals. With a focus on practical application, participants will engage in hands-on labs, building core skills.

Learners who successfully complete the course and pass the proctored, hands-on OSCC SEC-100 exam will earn the OffSec CyberCore Certified certification, validating their readiness to enter the cybersecurity field.

By the end of this course, learners will be able to:

• Identify offensive and defensive techniques used in modern cyber operations
• Apply basic scripting in Python and PowerShell to security tasks
• Configure and manage secure systems across Windows, Linux, and cloud environments
• Recognise and respond to common security incidents and threats
• Demonstrate secure-by-design principles in software and system architecture
• Understanding the anatomy of cybersecurity and the CIA Triad, a foundational model that defines core security objectives
• Integrating industry-recognised frameworks like NIST and ISO 27001 to implement effective security practices
• Address the risks and vulnerabilities associated with cloud computing
• Examine AI's influence, both as a threat and as a tool to enhance offensive and defensive capabilities
