Security domains are critical constructs in a physical network and within alogical environment, as in an operating system. Which of the following best describes how addressing allows for isolation?
A.
In a network domains are isolated by using IP ranges and in an operating systemdomains can be isolated by using MAC addresses.
B.
In a network domains are isolated by using subnet masks and in an operating system domains can be isolated by using memory addresses.
C.
Addressing is a way to implement ACLs, which enforce domain access attempts andboundaries
D.
Addressing creates virtual machines, which creates isolated domains.
Explanation:
Addressing is a way to enforce, "if you dont have this address you dont belong here." network domains we use IP ranges and subnet masks to control how networksegments communicate to each other. Within software processes can only communicateto the address space that the security kernel will allow. Addressing is one way to enforce domain access and its boundaries.
Correct answer is B
