• Design hardware, operating systems, software applications and secure interfaces to meet cybersecurity requirements across information systems, physical systems and embedded technologies. • Perform risk analysis (threat, vulnerability and probability of occurrence) when applications or systems undergo major changes and develop mitigation strategies for cost, schedule, performance and security risks. • Conduct security reviews to identify gaps in architecture, recommend security changes to system components and incorporate vulnerability solutions into system designs. • Design, develop, integrate and update system security measures that support confidentiality, integrity, availability, authentication and non-repudiation. • Develop detailed security design documentation for components and interfaces, including functional descriptions of security implementation and keep documentation current. • Identify components and elements, allocate security functions and describe relationships between system elements; trace requirements to design components and perform gap analysis. • Implement security designs for new or existing systems and direct remediation of technical issues discovered during testing and implementation (including interoperability and protocol issues). • Develop and direct system testing and validation procedures and documentation; analyze test data and translate results into evaluative conclusions. • Identify, assess and recommend cybersecurity or cybersecurity-enabled products for system use, ensuring compliance with organizational evaluation and validation requirements. • Provide input to implementation plans, SOPs, RMF process activities and documentation and support security/certification test and evaluation activities. • Build, test and modify prototypes using working or theoretical models; use models and simulations to predict performance under different operating conditions. • Verify stability, interoperability, portability and scalability of the system architecture and security design.
