The U.S. Government has long recognized the strategic and economic value of space operations, leading to initiatives like Space Policy Directive 5 (SPD-5) to address the growing cyber threats facing commercial space systems. NIST’s report, Cybersecurity for Commercial Satellite Operations (NIST IR 8270), supports SPD-5 by introducing the Cybersecurity Framework (CSF) to the commercial space sector. It provides structured guidance for satellite operators—particularly those managing uncrewed systems—to identify and mitigate cybersecurity risks throughout a satellite’s lifecycle. With the commercial space market expanding rapidly, cybersecurity must now be considered an operational requirement.
Understanding the Operational Landscape
NIST presents a conceptual high-level architecture of satellite operations divided into segments: space, ground, user, and communication links.

The space segment includes the satellite’s bus and payload, while command and control functions link terrestrial and orbital systems. The architecture also includes internal satellite cybersecurity measures, satellite-to-satellite communications, and mission functions like sensing and data acquisition. By mapping this ecosystem, NIST aims to help stakeholders assign cybersecurity responsibilities and understand dependencies across shared infrastructure.
Lifecycle Risks and Risk Management Priorities
Each phase of a satellite’s life—from design to decommissioning—presents unique cybersecurity challenges. Early phases like design and assembly involve significant supply chain risk and the need for embedded security mechanisms. During operations, threats like signal spoofing, denial-of-service (DoS) attacks, and data interception become paramount. Decommissioning, often overlooked, is identified as a high-risk phase requiring controlled data disposal and adherence to international standards. NIST emphasizes continuous risk assessment and encourages using compensating controls when legacy systems can’t support modern protections.
Applying the Cybersecurity Framework (CSF)
The CSF is a risk-based approach structured around five core functions: Identify, Protect, Detect, Respond, and Recover. These functions are further broken down into categories and subcategories aligned to cybersecurity outcomes. Operators can use the CSF to develop a “profile”—a set of cybersecurity requirements customized to their business and threat model. This profile helps organizations assess their current cybersecurity posture, determine a desired target state, conduct gap analyses, and prioritize remediation steps. NIST also provides references to NIST SP 800-53 controls and standards to guide implementation.
Notional Use Case and Profile Development
NIST illustrates the application of CSF through a detailed example involving a small company operating a commercial remote sensing satellite. The organization maps high-priority threats—such as jamming, spoofing, and code injection—to CSF subcategories. From there, it builds a Current Profile (existing protections), conducts a risk assessment to understand vulnerabilities and impact, and creates a Target Profile of desired cybersecurity controls. This process leads to an actionable cybersecurity roadmap tailored to mission-critical systems like communications, guidance control, and sensors.
Implementing and Iterating the Action Plan
Using the profile as a baseline, the organization defines specific measures to protect against unauthorized access, ensure data integrity, and detect and recover from cyber incidents. This includes applying multi-factor authentication, protecting data in transit and at rest, securing firmware updates, and joining threat-sharing communities like ISACs. NIST encourages organizations to regularly revisit and revise their profiles in response to evolving threats and changes in operations. Ongoing monitoring, stakeholder engagement, and alignment with standards-based controls ensure the plan remains effective and sustainable.
Charting a Secure Course for Space Commerce
Through this document, NIST underscores the necessity of integrating cybersecurity from the ground up in commercial space ventures. By adopting the Cybersecurity Framework, satellite operators can systematically address risks, protect their systems, and contribute to a safer space environment. As commercial space operations continue to evolve, this structured approach offers a foundation for resilience, interoperability, and trust across an increasingly interconnected orbit.
