Signing for Your Code: The Secure Software Development Self-Attestation

Published 2026 | TIKC NewsWire

If your company sells software to the federal government, or sells a product with software in it, a relatively new requirement has changed what your signature means. Before the government will use your software, a senior company official must attest that it was developed in line with recognized secure software development practices. This is not a checkbox a junior engineer clicks. It is a named executive putting the company’s word on the line, and like every certification in federal contracting, a false one is not just a compliance miss. It is potential fraud.

Where the requirement came from

After a series of high-profile software supply-chain attacks, the government moved to make security a condition of buying software, not an afterthought. The result is a self-attestation requirement built on a federal secure software development framework. Producers of software used by federal agencies must attest that they follow specified secure development practices, covering things like protecting their build environments, managing the provenance of components, and maintaining trusted processes for how code is written, tested, and shipped. For certain software, more detailed artifacts or third-party assessment can be required.

The attestation is a certification

The heart of the matter is that a senior official signs. That signature tells the government your development process actually meets the framework’s practices. If it does not, and you signed anyway, you have made a false statement to induce the government to use and pay for your software. This is the same enforcement logic driving the CMMC cybersecurity cases, where the gap between the security a contractor claimed and the security it had became the whole case. A software attestation you cannot back up is the same trap in a different form.

Why small software firms are exposed

Smaller producers feel this most. They may follow good practices informally but lack the documentation to prove it, or they rely on open-source components without tracking provenance, or they ship from build environments that were never hardened. The executive is then asked to attest to a maturity the company has not actually reached. The honest move is to close the gaps before signing, not to sign and hope. The same discipline that governs cyber incident reporting applies here: the signature creates a duty to have the thing you are claiming, and to be able to show it.

How to sign safely

Start by mapping your development process to the framework and finding the gaps honestly. Harden your build environment, track the provenance and components of what you ship, and document the practices you follow so there is evidence behind the attestation. Where you cannot yet meet a practice, understand whether a plan of action is acceptable and track it to completion rather than papering over it. And make sure the executive who signs actually understands what is being certified, because that person, and the company, own the consequences. Like the contractor in the cyber-score settlement, the ones who get hurt are those who signed for a security they did not have.

What to do now

• Map to the framework. Compare your development practices to the federal secure software development framework and identify gaps.
• Harden and document. Secure your build environment, track component provenance, and keep evidence of the practices you follow.
• Close gaps before signing. Fix shortfalls, or track them through a documented plan of action, before you attest.
• Brief the signer. Make sure the senior official understands exactly what the attestation certifies.
• Keep the proof. Maintain the records that would let you defend the attestation if it is ever questioned.

Selling software to the government now means standing behind how you built it. Do the work, document it, and let a senior leader sign from facts, and your attestation becomes a competitive strength instead of a liability. Brick by brick.

FAQ

What is the secure software development self-attestation?

A requirement that a senior official of a software producer attest that the software was developed following recognized secure development practices before federal agencies use it.

Who has to sign it?

A senior company official, not a junior engineer. That person and the company bear responsibility for the accuracy of the attestation.

What if my practices do not fully meet the framework yet?

Close the gaps before signing, or determine whether a documented plan of action is acceptable and track it to completion. Do not attest to a maturity you have not reached.

What is the risk of a false attestation?

Because the government relies on it to use and pay for your software, a false attestation can create False Claims Act exposure, the same theory used in cybersecurity certification cases.
