Author Mike Chapple, an IT leader with over 15 years experience, introduces identification methods such as usernames and biometrics, as well as authentication methods to verify users, including multifactor authentication, password authentication, and single sign-on. He also discusses authorization concepts such as mandatory and discretionary access controls, which can help you restrict access to sensitive parts of your network. The course also covers best practices for ongoing account management, such as establishing a good password policy, managing user roles, and monitoring accounts, and what to do when you need to suspend or terminate access.
