Which term describes software that connects computers and devices to other applications and networks?

• A. Sandboxing
• B. Security as a Service (SECaaS)
• C. Middleware
• D. Cloud Security Broker

Answer: (C)

Middleware is software that sits between operating systems and applications, enabling different computers and devices to communicate with one another and access other applications and networks. It provides the plumbing for integration—message queuing, data transformation, authentication, and service orchestration—so disparate systems can work together. This makes it the best fit for describing software that connects devices to other applications and networks. Sandboxing isolates code to prevent it from affecting other processes, so it’s not about connectivity. Security as a Service delivers protective capabilities from the cloud rather than serving as the connective layer. A Cloud Security Broker focuses on enforcing security across cloud services, not on enabling general connectivity. In practice, middleware examples include enterprise service buses, API gateways, and message brokers that link ERP, CRM, IoT devices, and cloud apps.
