       A File Format to Aid in Security Vulnerability Disclosure
                      draft-foudil-securitytxt-09

Abstract

   When security vulnerabilities are discovered by researchers, proper
   reporting channels are often lacking.  As a result, vulnerabilities
   may be left unreported.  This document defines a format
   ("security.txt") to help organizations describe their vulnerability
   disclosure practices to make it easier for researchers to report
   vulnerabilities.
