The OSI (Open Systems Interconnection) model was developed by the International Organization for Standardization (ISO) in the late 1970s and early 1980s. It was first published in 1984 as ISO 7498, and it provides a framework for understanding how different layers of a computer network interact with each other.
Today, we’ll be discussing techniques used in cryptography, which will help you understand how information is secured in today’s digital age. As a beginner in cybersecurity, understanding the various techniques used in cryptography is crucial for building a solid foundation in the field.
At the beginner level, you will learn the basics of cryptography, such as the meaning of terms like algorithms, keys, and encryption. You’ll learn about different types of encryption methods, such as symmetric and asymmetric encryption, and their real-world applications.
