The CSIRT (Computer Security Incident Response Team) is the beating heart of DIVD, responsible for scanning the Internet and notifying system owners of the vulnerabilities found in their systems. Within the CSIRT, the team of CNA Administrators is responsible for DIVD's role as CVE Number Authority (NA). They can independently assign CVE numbers and update CVE records for vulnerabilities within our scope.

DIVD has two teams of highly skilled security researchers who voluntarily seek out and report vulnerabilities alongside their regular jobs. DIVD ensures they adhere to our Code of Conduct while providing a buffer against journalists, lawyers, and recruiters. Their research not only uncovers security trends and raises awareness but also helps develop new methods for vulnerability research and disclosure. Although you may never meet our researchers, you can hope they are inspecting your systems right now, catching issues before the bad guys do....

A safe working environment DIVD continuously strives to be a safe and healthy organization, where everyone feels at home. Creating a workplace where individuals feel secure, included, valued, trusted and respected is crucial for fostering a positive and productive atmosphere. Maintaining such an environment is essential for the well-being and professional development of our workforce. Therefore DIVD has appointed confidential advisors, by which we aim to provide employees with a dedicated and trustworthy channel to address concerns related to unwanted behaviors or integrity violations. Unwanted behaviors, such as exclusion, bullying, harassment, discrimination, and aggression, can have a detrimental impact on an individual's well-being and the overall workplace environment. Similarly, integrity violations, encompassing actions like corruption, fraud, abuse of power, and disclosure of sensitive information, compromise the ethical foundation of an organization. DIVD acknowledges the severity of these issues and takes a proactive stance by not tolerating such behaviors. The presence of the confidential advisors underscores the importance of open communication, addressing issues promptly, and upholding ethical standards. By offering this support system, DIVD aims to ensure that employees feel heard, supported, and empowered to address concerns without fear of reprisal. Also, DIVD intends to strengthen the trusted relationship, reassure employees that their concerns are taken seriously, and demonstrate its commitment to maintaining a workplace where integrity is paramount.
