Final answer:
The components of the security kernel include software and hardware.
Step-by-step explanation:
Components of the Security Kernel
The security kernel is the core component of an operating system responsible for enforcing security policies. The options that are components of the security kernel are:
Software: The software components of the security kernel include the security modules, access controls, and security services that are implemented in the operating system.
Hardware: The hardware components of the security kernel refer to the physical components that support the security features, such as secure processors, encryption, and tamper-resistant devices.
The reference monitor and the trusted computing base are not components of the security kernel themselves, but represent key concepts within security architecture.
