In recent years, the federal government has heightened its focus on the security of the software supply chain, mandating stringent measures for software producers. As part of this initiative, the Executive Office of the President issued two key memoranda: M-22-18 and its update M-23-16. These memos require agencies to ensure software producers implement and attest to secure software development practices. This is where TestPros can step in as your trusted third-party assessor, providing the expertise and independence needed to meet these requirements.

Understanding the Requirements

The Office of Management and Budget (OMB) memos indicate that a software producer needs to self-attest or have a third-party assessment of practices for producing software securely. In place of a self-attestation, an acceptable assessment is done by an agency-approved assessment organization.

The Role of FedRAMP and CISA

The Federal Risk and Authorization Management Program (FedRAMP) has collaborated with OMB in adding further clarity to the requirements. They specifically allow independent assessments conducted by a 3PAO or an agency-approved assessment organization based on NIST Guidance. The evaluation would ensure that secure development practices were adhered to by software producers.

To facilitate this, the Cybersecurity and Infrastructure Security Agency (CISA) developed a portal through which software producers would submit their Secure Software Development Attestation Forms or third-party assessments. This central repository is to help the agencies collect and authenticate such attestations by the software producers in their quest for compliance with the mandates.
