  • Develop software system testing and validation procedures, programming, and documentation. (T0455)
  • Enable applications with public keying by leveraging existing public key infrastructure (PKI) libraries and incorporating certificate management and encryption functionalities when appropriate. (T0416)
  • Evaluate factors such as reporting formats required, cost constraints, and need for security restrictions to determine hardware configuration. (T0100)
  • Identify and leverage the enterprise-wide security services while designing and developing secure applications (e.g., Enterprise PKI, Federated Identity server, Enterprise AV solution) when appropriate. (T0417)
  • Identify basic common coding flaws at a high level. (T0111)
  • Identify security implications and apply methodologies within centralized and decentralized environments across the enterprises computer systems in software development. (T0117)
  • Identify security issues around steady state operation and management of software and incorporate security measures that must be taken when a product reaches its end of life. (T0118)
  • Modify and maintain existing software to correct errors, to adapt it to new hardware, or to upgrade interfaces and improve performance. (T0500)
  • Perform integrated quality assurance testing for security functionality and resiliency attack. (T0171)
  • Perform risk analysis (e.g., threat, vulnerability, and probability of occurrence) whenever an application or system undergoes a major change. (T0181)
  • Perform secure programming and identify potential flaws in codes to mitigate vulnerabilities. (T0176)
  • Store, retrieve, and manipulate data for analysis of system capabilities and requirements. (T0228)
  • Translate security requirements into application design elements including documenting the elements of the software attack surfaces, conducting threat modeling, and defining any specific security criteria. (T0236)
