Chapter: General Security Concepts
This lesson focuses on the cryptographic solutions that are vital for securing data and communications. We will explore key concepts such as Public Key Infrastructure (PKI), various encryption techniques, and methods for data obfuscation. Additionally, we will cover hashing, digital signatures, and the emerging technology of blockchain to help you understand how these tools ensure data integrity, confidentiality, and non-repudiation in a digital environment.
By the end of this lesson, you should be able to:
- Understand and explain the components of Public Key Infrastructure (PKI), including certificates, Certificate Authorities (CAs), registration authorities, and certificate revocation lists.
- Describe the different encryption methods: symmetric, asymmetric, stream, and block encryption.
- Explain data obfuscation techniques such as steganography, tokenization, and data masking.
- Understand the role of hashing algorithms like MD5, SHA, and HMAC in ensuring data integrity.
- Describe the function of digital signatures in authentication and non-repudiation.
- Explain blockchain technology, including its use of distributed ledgers and immutable record-keeping.
