A jump server is the best choice because it provides a controlled access point to sensitive internal resources. The company can configure the mission-critical database to accept administrative or management connections only from the jump server’s internal IP address. This reduces exposure by preventing direct access from general user workstations or broad network segments. The jump server can also enforce authentication, session logging, monitoring, and administrative access controls. A web application firewall protects web applications, not direct database access. A network tap passively copies traffic for monitoring and does not restrict access. An intrusion prevention system can block suspicious traffic, but it is not the best mechanism for limiting database access to specific internal IP addresses. The jump server fits the access-control requirement best.
