The US Federal Government's cybersecurity executive order recognizes the growing threat of software supply chain attacks and aims to minimize this risk by directing the Commerce Department to create strict standards for companies selling software to the Federal Government. The order requires software suppliers to implement secure development practices, provide a Software Bill of Materials (SBOM), attest to a secure development environment, and ensure open source integrity. To achieve these goals, developers are being empowered with developer-friendly tooling and proper guidance from security teams. The executive order also calls for early implementation of automated security testing across the software development process, securing all code making up modern software, and providing transparency through attestation and component-level reporting. As guidelines are introduced by NIST within six months to a year, companies selling to the Federal Government must start planning to identify major gaps with their existing software supply chain and comply with these new standards, which will likely trickle down into the private sector and affect the software market as a whole.
