Documented cybersecurity policies establish the foundational governance framework that defines how an organization protects its information assets, assigns security responsibilities, and ensures consistent security behavior across all personnel and organizational levels. For space mission organizations, these policies must address the unique threat environment, operational constraints, and asset types associated with spacecraft, ground systems, and mission data, providing a coherent governance layer that connects organizational security objectives to the technical controls and operational practices implemented throughout the mission lifecycle. Well-documented policies ensure that personnel at all levels, from executive leadership through program management to operations staff, understand their security roles and responsibilities, reducing the probability of security failures attributable to ambiguity, inconsistency, or lack of guidance. Policies establish organizational security objectives, authorities, responsibilities, and required outcomes. Risk assessments, system requirements, standards, plans, and procedures translate those policies into technical controls and operational practices. During a security incident, approved incident response plans and procedures provide the actionable guidance needed to implement organizational policy and support timely decision-making. Mission organizations must identify the legal, regulatory, contractual, policy, and licensing requirements applicable to their activities and ensure that their cybersecurity policies address those obligations. Documented policies may therefore serve both organizational governance and compliance purposes.
Assessment and authorization (A&A) is a structured, formal process through which an organization evaluates the extent to which a system's design and implementation satisfy a defined set of security requirements, and grants or denies authorization for that system to operate based on the assessed risk. For space mission systems, A&A may apply to spacecraft, ground systems, mission networks, supporting infrastructure, common controls, and the interfaces and dependencies among them. The authorization scope and boundary must be defined by the governing risk management framework, mission architecture, information types, applicable requirements, and organizational risk decisions. The assessment phase produces evidence concerning whether selected controls are implemented correctly, operating as intended, and producing the required security outcomes. The resulting authorization package should contain the system security plan, assessment reports, plan of action and milestones, executive risk summary, and other evidence required by the authorizing authority. The authorization decision, made by a designated authority with accountability for accepting the residual risk of operating the system, formally records the organization's acceptance of that risk and establishes the conditions under which the system may operate. Authorization must be supported throughout the system lifecycle by continuous monitoring, security impact analysis, updated risk information, and maintenance of the authorization evidence. Proposed system changes must be assessed before implementation when they could affect the authorization boundary, control implementation, or accepted risk. Significant changes or material deviations from the authorization basis must be reported to the authorizing authority, who determines whether additional assessment, modified authorization conditions, or reauthorization is required.
The [organization] shall have policies that clearly describe the processes and methodologies for conducting security assessments, obtaining authorizations, and performing continuous monitoring activities.{SV-DCO-1}{CA-1}
Explicit procedural guidance reduces inconsistency. Defined methodologies improve repeatability. Continuous monitoring integrates assessment into operations. Governance ensures sustained oversight.
SPR-381
The [organization] shall designate an authorizing official for the system.{SV-MA-6}{CA-6}
These officials must be federal employees, and are responsible for reviewing the security authorization package, assessing the risks, and making the decision to authorize system operation. They shall ensure compliance with relevant organizational policies and standards and are accountable for the decision to accept the risks associated with operating the system. The authorizing officials must be empowered with the authority to oversee and enforce the implementation and maintenance of security controls in accordance with organizational requirements and applicable regulations.
SPR-526
The [organization] shall tie go/no‑go authorizations to verified artifacts (flatsat/twin results, signed images, key ceremonies) and define how authorization boundaries adjust under contingency conditions; evidence shall be captured for A&A.{SV-MA-6,SV-SP-9}{CA-1,PL-2,CM-3}
Flight decisions must rely on validated artifacts. Evidence capture strengthens compliance. Contingency adjustments must remain controlled. Governance alignment supports mission safety.
