Foundation of Information Security12:20

Security Principles and Protection Models25:40
CIA Triad Explained with Real-World Examples12:40
The CIA Triad is one of the most important foundations of information security and cybersecurity. In this bonus lesson, we explore the CIA Triad using real-world business examples to understand how organizations protect customer information and services. You will learn: ? Confidentiality – How organizations protect sensitive information from unauthorized access. ✅ Integrity – How organizations ensure data remains accurate, trustworthy, and protected from unauthorized changes. ⚡ Availability – How organizations ensure systems and information are accessible when customers need them. Using examples from banking and e-commerce platforms, we explore how businesses apply the CIA Triad to protect customer trust, maintain secure operations, and reduce security risks. You will understand: Why confidentiality matters for customer privacy Why integrity is critical for accurate transactions Why availability is essential for business continuity How security controls support the CIA Triad This lesson is part of the Information Security Fundamentals: Cybersecurity Essentials learning series and is designed for beginners, IT professionals, cloud learners, and anyone interested in understanding the foundations of cybersecurity.
Security Controls by Function and Implementation13:39
In this lecture, we will explore how security controls are classified based on what they do and how they are implemented.
First, we will examine functional classifications, including preventive, detective, deterrent, and corrective controls, with practical examples of how each control helps reduce security risk.
Next, we will look at implementation classifications: administrative, technical, and physical controls. You will see how policies, processes, technology, and physical safeguards work together to protect organizational assets.
We will also connect both approaches using real-world examples, showing how a single security control can have more than one classification.
By the end of this lecture, you will have a clear understanding of security control classifications and how they are applied in real-world cybersecurity environments.
