Final answer:
The Scrum Master should address concerns about data security with the team and work together to find solutions.
Step-by-step explanation:
When a Development Team member expresses concerns about data security, the Scrum Master should address these concerns with the team. The Scrum Master plays a key role in facilitating communication and collaboration within the team, and it is their responsibility to create a safe environment for team members to raise their concerns and discuss potential solutions.
By addressing the concerns with the team, the Scrum Master can help identify any vulnerabilities or gaps in data security and work together with the team to find appropriate measures and solutions. This ensures that the team can continue working effectively while also maintaining data security.
Disregarding the concerns or reassigning the team member may lead to a negative work environment and could result in potential security breaches, so it is important for the Scrum Master to take the concerns seriously and actively engage in resolving them.
