CompTIA Security+ Certification SY0-601: The Total Course - Trust Models

The video tutorial discusses three types of trust used with certificates: self-signed certificates, web of trust, and public key infrastructure (PKI). Self-signed certificates are common in trusted environments but not in public ones. The web of trust involves individuals verifying each other, but it lacks widespread adoption due to its complexity. PKI, widely used today, relies on a hierarchical structure with certificate authorities issuing trusted certificates.
