Section V(B): Manufacturers should implement "Cybersecurity Risk Management Programs" that include "adopting a coordinated vulnerability disclosure policy and practice." Since the rule was published in 2016, it suggests that manufacturers make use of the ISO/IEC 29147:2014 (Information Technology - Security Techniques - Vulnerability Disclosure) Standard, which has since been replaced by a new version in 2018.
Section VII: Manufacturers should "adopt a coordinated vulnerability disclosure policy and practice that includes acknowledging receipt of the initial vulnerability report to the vulnerability submitter"
"To further incentivize the adoption of secure software development practices, the Administration will encourage coordinated vulnerability disclosure across all technology types and sectors."
Requires NIST to issue guidance identifying practices that enhance security of the software supply chain. In the guidance NIST must include standards, procedures, or criteria related to, among other issues, "participating in a vulnerability disclosure program that includes a reporting and disclosure process."
App Store Operators and App Developers listing apps on them should have a VDP (contact details/contact form); App Store Operators should verify that App Developers abide by these practices; App Store Operators should accept vulnerability disclosure reports on behalf of App Developers if they have not acknowledged the vulnerability - if the App Developer still fails to acknowledge the vulnerability, the App Store Operator should delist the app from its platform.
