In partnership with the Federal Bureau of Investigation (FBI), CISA released an update to joint guidance Product Security Bad Practices in furtherance of CISA’s Secure by Design initiative. This updated guidance incorporates public comments CISA received in response to a Request for Information, adding additional bad practices, context regarding memory-safe languages, clarifying timelines for patching Known Exploited Vulnerabilities (KEVs), and other recommendations.

While this voluntary guidance is intended for software manufacturers who develop software products and services in support of critical infrastructure, all software manufacturers are strongly encouraged to avoid these product security bad practices.

CISA and FBI urge software manufacturers to reduce customer risk by prioritizing security throughout the product development process. For more information and resources, visit CISA’s Secure by Design webpage or learn how to take CISA’s Secure by Design Pledge.
