CISSP® Certification Domain 3: Security Architecture and Engineering Video Boot Camp for 2022 - Secure operating systems

The video tutorial covers the ring model's efficiency in operating systems, comparing monolithic and microkernels, and their functionalities. It explains the role of the reference monitor in access control and discusses discretionary access control in Linux and Windows systems. The tutorial also provides practical guidance on managing permissions in Windows, highlighting the security tab and edit options.

What is a key characteristic of a monolithic kernel?

• It runs in user mode.

• It is smaller and has less native functionality.

• It is modular and can load additional functionalities.

• It is a static executable and runs in supervisor mode.

How do microkernels differ from monolithic kernels?

• They are larger and have more native functionality.

• They can run kernel modules in user mode.

• They cannot load additional functionalities.

• They always run in supervisor mode.

What is the role of the reference monitor in an operating system?

• It manages the execution of applications.

• It handles access between objects and subjects.

• It compiles kernel modules.

• It interfaces between hardware and software.

In Linux or Unix systems, what types of privileges can be set?

• Full control, modify, delete

• Read, modify, delete

• Read, write, execute

• Read, write, full control

What additional right does 'Full Control' include in Windows NTFS?

• Modify and delete

• Change permissions

• Read and write
