• Support integration of the application with the government-approved authentication and authorization solution.
• Implement or integrate role-based access controls for authorized internal and external users.
• Support Federal authentication requirements involving identification, identity verification, multifactor authentication, phishing resistance, FIPS-validated technologies, and secure session management.
• Apply secure software development practices throughout design, development, testing, and deployment.
• Support cybersecurity documentation, vulnerability remediation, code scanning, dependency management, and authorization activities.
• Work with cybersecurity and infrastructure personnel to address security controls without disrupting required operational workflows.
• Protect the confidentiality, integrity, and availability of TEDB data.
• Preserve current TEDB reporting capabilities while supporting future reporting expansion.
• Reimplement current Access reports within the web application, SQL environment, or an approved enterprise reporting capability.
• Support reports associated with requirements, test procedures, test cases, test observations, Test Observation Reports, risks, results, and requirements traceability.
• Develop exports and formatted data products required by Test and Evaluation personnel and program stakeholders.
• Support integration with SQL Server Reporting Services or another approved reporting platform when selected.
• Validate report output against the existing TEDB application.
