24 Opportunity for Research SE ActivitiesISSE ActivitiesDiscover NeedsThe systems engineer helps the customer understand and document the information management needs that support the business or mission. Statements about information needs may be captured in an information management model (IMM).Discover Information Protection NeedsThe ISSE helps the customer understand the information protection needs that support the mission or business. Statements about information protection needs may be captured in an Information Protection Policy (IPP).Mission/Business FunctionInformation Management Functions
25 Opportunity for Research SE ActivitiesISSE ActivitiesDefine System RequirementsThe systems engineer allocates identified needs to systems. A system context is developed to identify the system environment and to show the allocation of system functions to that environment. A preliminary system Concept of Operations (CONOPS) is written to describe operational aspects of the candidate system (or systems). Baseline requirements are established.Define System Security RequirementsThe ISSE allocates information protection needs to systems. A system security context, a preliminary system security CONOPS, and baseline security requirements are developed.
26 Opportunity for Research SE ActivitiesISSE ActivitiesDesign System ArchitectureThe systems engineer performs functional analysis and allocation by analyzing candidate architectures, allocating requirements, and selecting mechanisms. The systems engineer identifies components or elements, allocates functions to those elements, and describes the relationships between the elements.Design System Security ArchitectureThe ISSE works with the systems engineer in the areas of functional analysis and allocation by analyzing candidate architectures, allocating security services, and selecting security mechanisms. The ISSE identifies components or elements, allocates security functions to those elements, and describes the relationships between the elements.
27 Opportunity for Research SE ActivitiesISSE ActivitiesDevelop Detailed DesignThe systems engineer analyzes design constraints, analyzes trade-offs, does detailed system design, and considers life-cycle support. The systems engineer traces all of the system requirements to the elements until all are addressed. The final detailed design results in component and interface specifications that provide sufficient information for acquisition when the system is implemented.Develop Detailed Security DesignThe ISSE analyzes design constraints, analyzes trade-offs, does detailed system and security design, and considers life-cycle support. The ISSE traces all of the system security requirements to the elements until all are addressed. The final detailed security design results in component and interface specifications that provide sufficient information for acquisition when the system is implemented.
28 Opportunity for Research SE ActivitiesISSE ActivitiesImplement SystemThe systems engineer moves the system from specifications to the tangible. The main activities are acquisition, integration, configuration, testing, documentation, and training. Components are tested and evaluated to ensure that they meet the specifications. After successful testing, the individual components—hardware, software, and firmware—are integrated, properly configured, and tested as a system.Implement System SecurityThe ISSE participates in a multidisciplinary examination of all system issues and provides inputs to C&A process activities, such as verification that the system as implemented protects against the threats identified in the original threat assessment; tracking of information protection assurance mechanisms related to system implementation and testing practices; and providing inputs to system life-cycle support plans, operational procedures, and maintenance training materials.
29 Opportunity for Research SE ActivitiesISSE ActivitiesAssess EffectivenessThe results of each activity are evaluated to ensure that the system will meet the users’ needs by performing the required functions to the required quality standard in the intended environment. The systems engineer examines how well the system meets the needs of the mission.Assess Information Protection EffectivenessThe ISSE focuses on the effectiveness of the information protection—whether the system can provide the confidentiality, integrity, availability, authentication and non-repudiation for the information it is processing that is required for mission success.1.

66 Operational Definition of Variables Independent Variable: ISSE implementation is defined as the implementation of ISSE within a DoD IS/IT acquisition organization, where ISSE is defined as “an engineering process … that captures and refines information protection requirements and ensures their integration into IT acquisition processes through purposeful security design and configuration” (DoD, 2006, p. 19).Dependent Variable 1: Culture is defined as “a set of shared assumptions, values, and behaviors that characterize the functioning of an organization” (Schwalbe, 2006, p. Glossary 8).Dependent Variable 2: Leadership is defined as the actions of an individual, usually in a formal position of authority in an organization (management), “who focuses on long-term goals and big-picture objectives, while inspiring people to reach those goals” (Schwalbe, 2006, p. Glossary 6).
67 Operational Definition of Variables Dependent Variable 3: Planning is defined as the activities and processes used to devise and maintain a workable scheme to ensure organizational needs are met (adapted from Schwalbe, 2006, p. Glossary 8).Dependent Variable 4: Resources are defined as “skilled human resources (specific disciplines either individually or in crews or teams), equipment, services, supplies, commodities, materiel, budgets, or funds” (Program Management Institute, 2004, p. 372) but not the management of personnel as defined by leadership.Dependent Variable 5: Training is defined as “the level of learning required to adequately perform the responsibilities designated … and accomplish the mission” (DAU, 2005, p. B 170).

69 Plausibility of Rival Hypotheses Both type of development (NDI vice developmental) and type of acquisition (rapid vice traditional) will be accounted for and controlled as mediating variables.
