Coordinated Vulnerability Disclosure (English)
December 2022Gepubliceerd op: 26 juli 2021
At Streekziekenhuis Koningin Beatrix, Winterswijk, we work hard to maintain and improve the security of our (medical) devices, systems and services. No matter how much effort we put into system security, there might be vulnerabilities present. If you discover a vulnerability you can report it safely via our Coordinated Vulnerability Disclosure (CVD), so SKB can take safety measures.
Reporting a vulnerability
If you have found a vulnerability, we would like to hear about it so that we can take appropriate measures as quickly as possible. SKB is keen to cooperate with you to protect our clients and systems better. If you comply with our CVD policy we have no reason to take legal action against you regarding the reported vulnerability. We ask you to:
- Make sure that your findings are in scope. On www.z-cert.nl/cvd-english/ you can check what is considered to be out-of-scope.
- Send your findings to Z-CERT. To do this please use the mail template on www.z-cert.nl/cvd-english/ and send it to email@example.com encrypted with our PGP-key. Z-CERT is an organization that handles all cyber security issues on behalf of SKB. Z-CERT will work with you and SKB to make sure that your report is handled with care.
- Provide adequate information to allow us to investigate and reproduce the vulnerability. Fill out every aspect of the CVD-form. This helps to resolve the problem as quickly as possible. An IP address or URL of the affected system with a description of the vulnerability will usually be sufficient, although more information might be necessary for more complex vulnerabilities. You may add a proof of concept as an attachment.
- Do not exploit vulnerabilities, e.g. by downloading more data than is needed to demonstrate the vulnerability, looking into third-party data, deleting or modifying data.
- If you suspect to have access to medical data we ask you to let us verify this.
- Do not share information on vulnerabilities until they have been resolved and erase any obtained data as soon as the problem is solved.
- Do not attack (physical) security using social engineering, distributed denial of service, spam, brute force attacks, third-party applications for instance, or other types of attacks.
How we will handle your report
- SKB and Z-CERT will treat your report confidentially and will not share your personal data unless required by law.
- Z-CERT will send you a confirmation of receipt and will respond within five working days with an evaluation of your report and an expected resolution date.
- SKB and Z-CERT will keep you informed of the progress in resolving the problem.
- In communication about the reported problem we will mention your name as the discoverer of the problem (unless you desire otherwise).
We strive to resolve any vulnerability as soon as possible. Once the problem has been resolved we will decide in consultation whether and how details will be published.
