Public Key Infrastructure (PKI) Explained (Bare Metal Cloud Security Series)

This video dives deep into the world of Public Key Infrastructure (PKI), explaining how it secures communication between your browser and a web server. We start with the basics of setting up a website and quickly move to the issue of hacker interception and the need for secure communication. What you will learn: - The difference between a public key (for encryption) and a private key (for decryption). - How asymmetric encryption and a symmetric key work together to secure a session efficiently. - What a man-in-the-middle attack is and how a Certificate Authority (CA) prevents it. - The purpose of a Trust Store and why operating systems trust certain CAs. - The Chain of Trust flow: Root Certificate, Intermediate Certificate, and Leaf Certificate. - The use of Subject Alternative Name (SAN) and wildcard certs for domain protection.
