NTIA Early Stage Template
The NTIA Early Stage Template focuses on vulnerability disclosure policy development in safety-critical industries, in which the potential for harm directly impacts public safety or causes physical damage (e.g., automobiles or medical devices), but the lessons are easily adaptable by any organization that builds or maintains its own software or systems. A discussion of issues and template policy is included.
Open Source Vulnerability Disclosure Framework
BugCrowd and CipherLaw created the Open Source Vulnerability Disclosure Framework, offered under a Creative Commons Attribution 4.0 International License. The framework "is designed to quickly and smoothly prepare your organization to work with the independent security researcher community while reducing the legal risks to researchers and companies." In addition to a policy template "written with both simplicity and legal completeness in mind," a guidance document is provided for setting up a vulnerability disclosure program.
U.S. GSA Vulnerability Disclosure Policy
The United States General Services Administration (GSA)'s Technology Transformation Service (TTS) provides its vulnerability disclosure policy as a public domain resource.
ENISA Good Practice Guide on Vulnerability Disclosure
The Good Practice Guide on Vulnerability Disclosure from European Union Agency for Network and Information Security (ENISA) includes an annotated vulnerability disclosure policy template as an Annex.
US Department of Justice Framework for a Vulnerability Disclosure Program for Online Systems
The United States Department of Justice (DoJ) has published a white paper containing guidance aimed at developing vulnerability disclosure programs for online systems and services. This report makes a point to distinguish online systems and services from "third-party vulnerability disclosure and hands-on—rather than remote—examination of software, devices, or hardware" because of potentially distinct legal issues that may arise.
The aforementioned report is one of many related white papers provided by the DoJ's Computer Crime and Intellectual Property section.
Where to Look for More
Numerous organizations have already posted their vulnerability disclosure policies. A wide variety of these policies can be found by searching the web for "vulnerability disclosure policy," or "vulnerability disclosure program," or by browsing third-party vulnerability disclosure (e.g., bug bounty) service providers' hosted programs.
