What are the key elements of operating system security and the methods of user authentication?
Understand the Problem
The question is an overview of operating system security, including concepts like user authentication, secure design principles, security models, and certification aspects. It addresses various methods of user authentication such as password-based, biometric, and multi-factor authentication, alongside principles of secure design like least privilege and separation of privilege.
Answer
Key elements: authentication, authorization. Methods: password, multi-factor, biometrics.
Key elements of operating system security include authentication, authorization, encryption, integrity, and auditing. User authentication methods comprise password-based authentication, multi-factor authentication, biometric recognition, security tokens, and knowledge-based authentication.

More Information
Operating system security ensures system resources are protected from unauthorized access. Authentication is the first line of defense and is crucial for securing computer systems.
Tips
A common mistake is confusing authentication (verification of identity) with authorization (granting access rights). Ensure understanding of the difference between these concepts.
