Clearance Requirement: TS Clearance with SCI eligibility

Position Description:

The Information Systems Security Engineer (ISSE) supports the Information Technology (IT) Architecture and Engineering (A&E) team as the Subject Matter Expert (SME) in the System Security Engineering (SSE), Cyber Resiliency, and the overall information system security engineering processes. The ISSE works directly with the Activity’s Information Security Architect (ISA), Enterprise Architects, and System Engineers (SSEs)to ensure that SSE and Cyber Resiliency objectives, techniques, approaches, and design principles are fully represented and included in all systems engineering and development efforts. The ISSE's involvement is ever present through-out the systems development life cycle (SDLC) to include requirements definition, design, engineering, implementation, testing, validation, verification, continuous monitoring, and on-going vulnerability remediation for all information systems under the cognizance of the Activity's Chief Information Officer (CIO). The ISSE is ultimately responsible for protecting the CIO's information systems from unauthorized system activity or behavior to provide confidentiality, integrity, and availability. Responsibilities of the ISSE include, but are not limited to:

  • Discover Information System Protection Needs through analyzing the Activity's mission; identifying legal and regulatory requirements; identify classes of threats; determining impacts against risk; identifying security services; documenting the protection needs; and identifying design constraints.
  • Define System Security Requirements by developing the system security context, Security Concept of Operations (CONOPs), and Security Requirements Baselines from the gathered Customer and Stakeholder requirements.
  • Design System Security Architecture by working with SEs in 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.
  • Develop Detailed Security Design by analyzing design constraints, analyzing trade-offs, generating detailed system and security design, with life-cycle support consideration.
  • Implement System Security from the hands-on approach to participation in a multidisciplinary examination of all systems issues that provides input to the Certification and Accreditation(C&A) process activities.
  • Assess Information Protection Effectiveness by focusing on the effectiveness of the information protection whether the system can provide confidentiality, integrity, availability, authentication, and nonrepudiation for the information it is processing that is required for mission success.
