Security Concepts and Authentication Methods

The video tutorial by Tech G covers key concepts in cybersecurity, including authentication, authorization, accounting, and non-repudiation. It explains different authentication methods like single-factor and multi-factor authentication, and discusses authorization and permissions, including access control models such as role-based and rule-based access. The tutorial also covers user account types across various operating systems, accounting methods for tracking user activities, and non-repudiation techniques using digital signatures and biometrics. The session concludes with review questions to reinforce learning.
