Responsible Disclosure Practices
When Security Engineers or independent researchers discover vulnerabilities in software or systems, the process of disclosing this information raises ethical questions. Responsible disclosure aims to inform the vendor or owner of the system privately, allowing them time to develop and deploy a fix before the vulnerability is made public.
This contrasts with full disclosure (immediately making the vulnerability public) or non-disclosure (keeping it secret). Responsible disclosure seeks to balance the public's right to know about risks with the need to prevent malicious actors from exploiting the vulnerability before a patch is available.
Engineers involved in vulnerability research or handling reports from external researchers must adhere to ethical disclosure policies. This involves coordinating with vendors, setting reasonable timelines for fixes, and deciding when and how to publicly release information if necessary to protect users.
