The VCDV acts as the central expertise centre for digital security within the Flemish government and supports both Flemish entities and local authorities with expertise, services and coordination on cybersecurity.
• Within this context, a structural service is being developed, with the aim of identifying vulnerabilities in a timely manner and supporting organisations within the Flemish government and local authorities in strengthening their digital security.

TECHNICAL CONTEXT:

• The technical environment in which these services are offered is very diverse and includes a variety of technologies, platforms and architectures that are used within the Flemish government and by local authorities.

You validate findings, place them in their risk context and translate them into concrete recommendations. In doing so, you will support Flemish entities and local authorities in prioritising and following up on remediation actions.
• Automation is an essential part of the job. Given the volume of sources, data, and audiences, you'll develop and maintain scripts — primarily in Python — and integrations that support the collection, enrichment, correlation, follow-up, and reporting of vulnerability information.
• You will work closely with internal teams, external service providers and representatives of Flemish entities and local authorities. You provide timely insight into vulnerabilities and exposed systems and provide the corresponding recommendations, so that the organisations involved can remediate in a targeted manner.
• In addition, you also support initiatives around cyber awareness and phishing simulations.
• The position is executive and supportive in nature and combines substantive expertise with a strong operational focus. In addition to the analysis and follow-up of files, you will take an active role in the daily operation of the service and contribute to the further professionalization of processes, working methods and supporting solutions.
