The correct answer is Layer 4.In the OSI (Open Systems Interconnection) model, Layer 4 is the Transport layer. This layer is responsible for providing reliable data transfer services to the upper layers, including the identification and configuration of application ports.When a security engineer configures software-based port security on a hardware firewall, they are working at the Transport layer (Layer 4) of the OSI model. This layer is responsible for identifying the application ports to configure, as well as ensuring the secure transmission of data between devices.The other layers of the OSI model have different responsibilities:- Layer 1 (Physical layer) is responsible for the physical transmission of data between devices.- Layer 2 (Data Link layer) is responsible for the reliable transmission of data over a physical medium.- Layer 3 (Network layer) is responsible for the routing and addressing of data between networks.Therefore, the correct answer is that the Transport layer (Layer 4) of the OSI model identifies the application ports to configure when setting up software-based port security on a hardware firewall.
