Instructions: Answer all questions in a single document. Then submit to the
appropriate assignment folder. Each response to a single essay question should
be about a half-page in length (about 150 words).

1. Not all information has the same importance and value to a company. How
data is classified is an important factor used in determining the amounts of
funding and resources that should be applied to protecting each type of
data. Describe the data classification levels within commercial and military
organizations and provide examples of the types of information that would
be classified at each classification level.

2. It takes a team of individuals throughout the organization working together
to safeguard the integrity and confidentiality of data resources. Describe
the layers of responsibility within an organization when it comes to asset
security and data protection. For each role, discuss their responsibility
within the organization for asset security.

3. The architecture of a computer system is very important and comprises
many topics. The system must ensure that memory is properly segregated
and protected, ensure that only authorized subjects access objects, ensure
that untrusted processes cannot perform activities that would put other
processes at risk, control the flow of information, and define a domain of
resources for each subject. It also must ensure that if the computer
experiences any type of disruption, it will not result in an insecure state.
Many of these issues are dealt with in the system’s security policy, and the
security mode is built to support the requirements of this policy. Explain
the concept of a trusted computing base and describe how it is used to
enforce the system’s security policy. Provide examples of specific elements
(hardware, software or firmware) in the architecture of the computer
system could be used that provide security within the TCB.
