Which of the following are tools to implement security functions?$$

Being relatively small, the security kernel can be analyzed rigorously. For example, formal methods can be used to ensure that all security situations $($such as states and state changes$)$ have been covered by the design.

$-$ Virtualization

$-$ Virtual Machine

$-$ Hypervisor

$-$ Sandbox

$-$ Honeypot

$-$ Separation and Sharing

$-$ Hardware Protection of Memory

$-$ Fence

$-$ Base$/$Bounds Registers

$-$ Tagged Architecture

$-$Virtual Memory

$-$ Segmentation

$-$ Paging

$-$ Combined Paging with Segmentation

In a multiprogramming environment, activation and

deactivation of processes occur frequently. Changing from one process to another requires a complete change of registers, relocation maps, file access lists, process status information, and other pointers, much of which is security$-$sensitive information.
