Learn the basics of cybersecurity and the CIA triad: confidentiality, integrity, and availability, through simple explanations and everyday examples, including passwords, backups, and secure online practices.
Explore security governance and risk management to protect data through policies, procedures, and standards. Apply four risk steps: find, study, plan, check, with malware, phishing, data breaches, and cyber attacks.
Learn how access control models and mechanisms keep digital systems safe by deciding who can read or modify information, with DAC, MAC, and RBAC, plus authentication, encryption, and firewalls.
Explore security models and architecture that protect data, including Bell-LaPadula and Biba, and practices like defense in depth, least privilege, and separation of duties in real-world banks and schools.
Implement defense in depth by layering security across data, apps, host, network, and perimeter. Learn how tools like firewall, encryption, multi-factor authentication, backups, and access control work to protect systems.
Learn threat modeling to identify attack surfaces and common threats like malware and phishing, then apply protections such as updates, strong passwords, backups, and user training.
Are you ready to dive into the world of cybersecurity and build a solid foundation for a future-proof career?
This course, Cybersecurity Principles and Models, is designed to help beginners and aspiring professionals understand the essential building blocks of modern information security. Whether you are a student, IT professional, or someone curious about how digital systems are protected — this course is your perfect starting point.
You’ll begin by exploring the CIA Triad — Confidentiality, Integrity, and Availability — the core principles that guide every security decision. Then, you’ll learn how organizations develop security governance policies and manage risks in real-world environments.
We’ll break down various access control models such as DAC, MAC, and RBAC, and show you how these frameworks help prevent unauthorized access. You’ll also discover classic security models like Bell-LaPadula and Biba, and how they apply to secure system architecture.
But that’s not all — the course also introduces the concept of defense in depth, showing how layered security is used to strengthen protection across systems. You’ll also gain practical insights into threat modeling and how to identify potential attack surfaces.
By the end of this course, you’ll be equipped with the fundamental knowledge needed to pursue cybersecurity certifications or move forward in your career confidently.
No prior experience required — just curiosity and a willingness to learn!
