Acquisition Security
Acquisition security refers to the proactive planning and integration of security measures into the process of obtaining a system, product, or service, so that risks are addressed before and during procurement rather than after deployment. It generally involves coordination among procurement officials, security teams, and suppliers to manage risks across the supply chain. The specific practices and scope can vary by organization and by the type of system being acquired, so readers should confirm requirements against current authoritative guidance.
Acquisition security is the discipline of embedding security considerations into the acquisition lifecycle, defined broadly as the process of obtaining a system, product, or service (per NIST terminology). In defense contexts it is generally described as the proactive planning and integration of all security disciplines and other defensive methods into the defense acquisition process to protect weapons systems and related capabilities. Structured approaches such as the Acquisition Security Framework (ASF), developed by the Carnegie Mellon Software Engineering Institute (SEI), provide a framework of practices intended to help programs coordinate the management of engineering and software supply chain risks across systems, offering greater insight and control over the software supply chain. Complementary resources, such as the CISA Software Acquisition Guide, are intended to support dialogue among procurement officials, government security teams, and software providers. The precise practices, applicability, and any binding versus advisory status depend on the governing organization and program, and this entry does not cover contractual, program-specific, or implementation details, which the reader should verify against the current authoritative sources.
Why it matters
Security weaknesses introduced during acquisition are far harder and more costly to remediate once a system, product, or service is already deployed. When security is bolted on after procurement rather than planned in advance, organizations inherit supply chain risks, engineering flaws, and integration gaps that may not surface until the capability is in operation. Acquisition security addresses this by shifting attention to the earliest phases of obtaining a system, where decisions about suppliers, requirements, and controls have the greatest leverage.
In defense contexts, the stakes are particularly high because acquisition security is generally described as protecting weapons systems and related capabilities through the proactive integration of security disciplines into the acquisition process. A compromised or poorly vetted component in the software supply chain can propagate risk across an entire program. Structured approaches such as the Acquisition Security Framework (ASF), developed by the Carnegie Mellon Software Engineering Institute, are intended to give programs greater insight and control over the software supply chain by coordinating the management of engineering and supply chain risks across systems.
It is worth emphasizing that acquisition security is a planning and coordination discipline, not a guarantee of a secure outcome, and that compliance with an acquisition process is not the same as achieving security. Resources such as the CISA Software Acquisition Guide are intended to support dialogue among procurement officials, government security teams, and software providers, but the precise practices, applicability, and whether guidance is binding or advisory depend on the governing organization and program. Readers should verify specific requirements against current authoritative sources.
