It is not a responsibility of a data owner. The data custodian (information custodian) is responsible for maintaining and protecting the data.

Answer: B, A, and C are incorrect. All of these are responsibilities of a data owner. The roles and responsibilities of a data owner are as follows: The data owner (information owner) is usually a member of management, in charge of a specific business unit, and is ultimately responsible for the protection and use of a specific subset of information. The data owner decides upon the classification of the data that he is responsible for and alters that classification if the business needs arise. This person is also responsible for ensuring that the necessary security controls are in place, ensuring that proper access rights are being used, defining security requirements per classification and backup requirements, approving any disclosure activities, and defining user access criteria. The data owner approves access requests or may choose to delegate this function to business unit managers. And it is the data owner who will deal with security violations pertaining to the data he is responsible for protecting. The data owner, who obviously has enough on his plate, delegates responsibility of the day-to-day maintenance of the data protection mechanisms to the data custodian.

The different tasks performed by the owner are as follows: He makes the original determination to decide what level of classification the information requires, which is based on the business requirements for the safety of the data. He reviews the classification assignments from time to time and makes alterations as the business needs change. He delegates the responsibility of the data safeguard duties to the custodian. He specifies controls to ensure confidentiality, integrity and availability. Answer: C is incorrect. This task is performed by the custodian and not by the owner.

In the waterfall model, software development can be managed if the developers are limited to go back only one stage to rework. If this limitation is not imposed mainly on a large project with several team members, then any developer can be working on any phase at any time, and the required rework might be accomplished several times. Answer: B is incorrect. The spiral model is a software development process combining elements of both design and prototyping-in- stages, in an effort to combine advantages of top-down and bottom-up concepts. The basic principles of the spiral model are as follows: The focus is on risk assessment and minimizing project risks by breaking a project into smaller segments and providing more ease-of- change during the development process, as well as providing the opportunity to evaluate risks and weigh consideration of project continuation throughout the life cycle. Each cycle involves a progression through the same sequence of steps, for each portion of the product and for each of its levels of elaboration, from an overall concept-of-operation document down to the coding of each individual program. Each trip around the spiral traverses the following four basic quadrants: Determine objectives, alternatives, and constraints of the iteration. Evaluate alternatives, and identify and resolve risks. Develop and verify deliverables from the iteration. Plan the next iteration.

Begin each cycle with an identification of stakeholders and their win conditions, and end each cycle with review and commitment. Answer: D is incorrect. The Prototyping model is a systems development method (SDM). In this model, a prototype is created, tested, and then reworked as necessary until an adequate prototype is finally achieved from which the complete system or product can now be developed. Answer: C is incorrect. Rapid Application Development (RAD) refers to a type of software development methodology that uses minimal planning in favor of rapid prototyping.

DITSCAP stands for DoD Information Technology Security Certification and Accreditation Process. The DoD Directive 5200.40 (DoD Information Technology Security Certification and Accreditation Process) established the DITSCAP as the standard C&A process for the Department of Defense. The Department of Defense Information Assurance Certification and Accreditation Process (DIACAP) is a process defined by the United States Department of Defense (DoD) for managing risk. DIACAP replaced the former process, known as DITSCAP, in 2006. Answer: B is incorrect. This DoD Directive is known as National Industrial Security Program Operating Manual. Answer: C is incorrect. This DoD Directive is known as Defense Information Management (IM) Program. Answer: A is incorrect. This DoD Directive is known as Management and Control of Information Requirements.
