M3AAWG has submitted comments to the Cybersecurity and Infrastructure Security Agency (CISA), Department of Homeland Security (DHS), Request for Comment on Product Security Bad Practices Guidance. M3AAWG generally supports the stated goals of reducing customer risk by prioritizing security throughout the product development process and discouraging the use of bad security practices, particularly where critical infrastructure and national critical functions are potentially impacted. However, the document lacks clarity on its role and purpose in relation to other CISA publications and comments. The draft guidance does not specify who is responsible for taking action, what specific actions are required, and which level of the security management stack this document is meant to address. These elements should be clarified throughout. Merely avoiding bad practices will not be sufficient to meet security standards. Avoiding bad practices must be supplemented with industry-standard security best practices. In addition, since CISA has previously issued advice on many of the areas covered, it would be helpful to clarify the objectives of this new draft guidance, the context for its release, and how it modifies or complements past guidance. For example, if the intent is to reinforce or summarize existing recommendations, this should be stated explicitly. Conversely, if the document introduces new recommendations or updates, those changes should be clearly highlighted.
