ISAUnited's Complimentary Content
Engineering Concepts

The Cybersecurity Engineering Concepts (CEC) framework equips engineers with a structured approach to implementing and validating security solutions. Rooted in Systems Engineering principles, CEC bridges the gap between architectural vision and operational execution by emphasizing Systems Thinking, Design Methodology, and Engineering Process Management. It provides engineers with the tools to translate strategic goals into actionable outcomes, ensuring compliance with standards like NIST and ISO while addressing complex challenges such as threat detection, incident response, and data protection.
Design Models

The Cybersecurity Design Model (CDM) framework focuses on creating robust, adaptable security architectures aligned with organizational objectives and industry standards. Designed for architects, the CDM emphasizes modularity, precision, and collaboration to build defensible systems. By leveraging tools like Exposure Mapping and Validation Frameworks, the CDM enables security teams to design scalable solutions and bridge the divide between high-level strategy and practical implementation. Together, CEC and CDM ensure seamless security integration by design across organizations.
