Categorize, secure, and manage national security systems with confidence. Discover a structured, model-driven approach to applying CNSSI 1253 guidance, enabling organizations to define system impact levels, select security controls, and ensure compliance across the lifecycle.
The Committee on National Security Systems Instruction (CNSSI) provides guidance for categorizing national security systems and selecting baseline security controls. CNSSI aligns with NIST standards and extends them to address the unique requirements of national security systems.
What CNSSI Does
CNSSI helps organizations implement consistent and compliant cybersecurity practices. It generally includes:
System categorization: Defining impact levels (confidentiality, integrity, availability) based on mission and data sensitivity.
Control selection: Mapping appropriate security controls to system categories using CNSSI and NIST guidance.
Compliance alignment: Ensuring systems meet federal and national security cybersecurity requirements.
Risk management support: Enabling informed decisions through structured control selection and risk evaluation.
