Security policy

The security policy given below is based on https://www.responsibledisclosure.nl/en/ by the Dutch National Cyber Security Centre and slightly adapted to the specific case of this website and other websites that fall under my administration.

Responsible disclosure

I consider the security of my systems a top priority. But no matter how much effort I put into system security, there can still be vulnerabilities present.

If you discover a vulnerability, I would like to know about it, so I can take steps to address it as quickly as possible. I would like to ask you to help me better protect my systems.

Please do the following:

  • Contact me as described on the security contact page.
  • Do not take advantage of the vulnerability or problem you have discovered, for example by downloading more data than necessary to demonstrate the vulnerability or deleting or modifying any of the data.
  • Do not reveal the problem to others until it has been resolved.
  • Do not use attacks on physical security, social engineering, distributed denial of service, spam or applications of third parties.
  • Do provide sufficient information to reproduce the problem, so I will be able to resolve it as quickly as possible. Usually, the IP address or the URL of the affected system and a description of the vulnerability will be sufficient, but complex vulnerabilities may require further explanation.

What I promise:

  • I will respond to your report within 3 business days with my evaluation of the report and an expected resolution date.
  • If you have followed the instructions above, I will not take any legal action against you in regard to the report.
  • I will handle your report with strict confidentiality, and not pass on your personal details to third parties without your permission.
  • I will keep you informed of the progress towards resolving the problem.
  • In the public information concerning the problem reported, I will give your name as the discoverer of the problem (unless you desire otherwise).

I strive to resolve all problems as quickly as possible and I would like to play an active role in the ultimate publication on the problem after it is resolved.
