Reducing susceptibility to cyber threats requires a multidimensional systems engineering approach. Security Architecture and Design Harden the Limit damage System target to the target Achieving Trustworthiness and Resiliency Make the target survivable NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY

TACIT Security ▪ T hreat MERRIAM - WEBSTER DICTIONARY ▪ A ssets tac . it adjective : expressed or understood ▪ C omplexity without being directly stated ▪ I ntegration ▪ T rustworthiness NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY 8

Threat ▪ Develop a better understanding of the modern threat space , including the capability of adversaries to launch sophisticated, targeted cyber-attacks that exploit specific organizational vulnerabilities. ▪ Obtain threat data from as many sources as possible. ▪ Include external and insider threat analysis. NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY 9

Assets ▪ Conduct a comprehensive criticality analysis of organizational assets including information and information systems. ▪ Focus on mission/business impact. ▪ Use triage concept to segregate assets by criticality. NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY 10

Complexity ▪ Reduce the complexity of the information technology infrastructure including IT component products and information systems. ▪ Employ enterprise architecture to consolidate, optimize, and standardize the IT infrastructure. ▪ Adopt cloud computing architectures to reduce the number of IT assets through on-demand provisioning of services. NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY 11

Integration ▪ Integrate information security requirements and the security expertise of individuals into organizational development and management processes . ▪ Embed security personnel into enterprise architecture, systems engineering, SDLC, and acquisition processes. ▪ Coordinate security requirements with mission/business owners; become key stakeholders. NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY 12

Trustworthiness ▪ Invest in more trustworthy and resilient information systems supporting organizational missions and business functions. ▪ Isolate critical assets into separate enclaves. ▪ Implement security design concepts (e.g., modular design, layered defenses, component isolation, least functionality, least privilege).
