Jobs Annual report Contact CSR report EN EXPERTISE EQUIPMENT PROJECTS NEWS SUSTAINABILITY ABOUT US Jan De Nul policy of coordinated disclosure of vulnerabilities (also known as the ‘Responsible Disclosure Policy’) so that you can inform us when you discover a vulnerability. Jan De Nul considers it important that its information and systems are secure. Despite our concern for the security of these systems, it may occur that there still is a vulnerability. If you have found a vulnerability in one of our systems, please let us know so that we can take measures as quickly as possible. We would like to work with you to protect our audience and our systems in a better way. We have therefore opted for a policy of coordinated disclosure of vulnerabilities (also known as the ‘Responsible Disclosure Policy’) so that you can inform us when you discover a vulnerability. This Responsible Disclosure Policy applies to all Jan De Nul systems. In any case of doubt, please contact us to clarify matters via CISO@jandenul.com. WHAT WE ASK OF YOU? If you discover a vulnerability in one of our systems, we ask you to: Reporting the vulnerability Report the vulnerability as soon as possible after discovery. Mail your findings to CISO@jandenul.com and encrypt them with our PGP key to prevent the information from falling into the wrong hands. Provide sufficient information to reproduce the vulnerability so that we can solve the problem as quickly as possible. Usually the IP address or URL of the affected system and a description of the vulnerability are sufficient, but for vulnerabilities that are more complex more information may be needed. Leave your contact details, so that Jan De Nul can contact you to work together for a safe result. Leave at least your name, e-mail address and/or telephone number. Reporting under a pseudonym is possible, but make sure that we can contact you if we should have additional questions. Confirm that you have acted and will continue to act in accordance with this Responsible Disclosure Policy. Rules you must follow Do not disclose the vulnerability until we have been able to correct it. See below for possible publication. Do not exploit the vulnerability by unnecessarily copying, deleting, adapting or viewing data or, for example, by downloading more data than is necessary to demonstrate the vulnerability. Don’t apply the following actions: Placing malware (virus, worm, Trojan horse, etc.). Copying, modifying or deleting data in a system. Making changes to the system. Repeatedly accessing the system or sharing access with others. Using automated scanning tools. Using the so-called "brute force" of access to systems. Using denial-of-service or social engineering (phishing, vishing, spam,...). Don’t use attacks on physical security, social engineering, distributed denial of service, spam or third-party applications. Immediately erase all data obtained through vulnerability as soon as it is reported to Jan De Nul. Don’t perform actions that could have an impact on the proper functioning of the system, both in terms of availability and performance, but also in terms of confidentiality and integrity of the data. Acts under this Responsible Disclosure Policy should be limited to conducting tests to identify potential vulnerabilities, and sharing this information with Jan De Nul. If, after the vulnerability has been removed, you wish to publish information about the vulnerability, we ask you to notify us at least one month before publication, and to give us the opportunity to respond. Identifying us in a publication is only possible after we have given our explicit approval. What we promise If you have complied with the above terms of the Responsible Disclosure Policy and have not committed any other breaches, we will not take any legal action against you. We will respond to your report within a short period of time, if possible within 10 working days, with our review of the report and any expected date for resolution. We will treat your report confidentially and will not share your personal data with third parties without your consent unless this is necessary to comply with a legal obligation. We will keep you informed of the progress of solving the problem. To thank you for any report of a security problem that is not yet known to us, we offer the opportunity to be listed in our "Hall Of Fame". We strive to solve all problems within a short period of time. We may choose to ignore low quality reports. If you have any questions, we encourage you to address them to CISO@jandenul.com. In case of doubt about the applicability of this policy, please contact us first via this e-mail address, to ask for explicit permission. We reserve the right to change the content of this Policy at any time, or to terminate the Policy.
