A passive interface is specifically designed to monitor copied network traffic received from a switch SPAN or mirror port. Because the Secure Firewall Threat Defense device is not physically placed in the traffic path, it receives a copy of the packets for inspection but does not retransmit them. This provides network and intrusion visibility without affecting production traffic. The trade-off is that a passive deployment cannot directly block, shape, or modify the monitored traffic because the original packets continue through the switch independently. An inline deployment, by comparison, places paired interfaces directly in the forwarding path and can drop malicious traffic. Routed and transparent describe firewall forwarding modes and are not the appropriate SPAN-based IPS interface type. Therefore, a SPAN-port monitoring deployment requires a passive interface.

The Cisco Threat Response browser plugin provides contextual investigation capabilities that can be launched from Secure Firewall Management Center. It allows an administrator to investigate an observable, such as a suspicious IP address, against Cisco threat-intelligence and integrated security sources without manually transferring the value to another interface. Secure Network Analytics analyzes network telemetry and behavior but is not the browser-based lookup mechanism described. Cisco ISE supplies identity, authorization, and network-access context, while Secure Endpoint provides endpoint telemetry and file or process investigation. Neither is the direct web-page investigation tool requested. Cisco documentation describes contextual cross-launch functionality for looking up suspicious source addresses in Cisco or third-party cloud-hosted intelligence services. Therefore, the Threat Response browser plugin is the correct selection. Cisco event investigation using web resources

Inline tap monitor-only mode (ASA inline)—In an inline tap monitor-only deployment, a copy of the traffic is sent to the ASA FirePOWER module, but it is not returned to the ASA. Inline tap mode lets you see what the ASA FirePOWER module would have done to traffic, and lets you evaluate the content of the traffic, without impacting the network. However, in this mode, the ASA does apply its policies to the traffic, so traffic can be dropped due to access rules, TCP normalization, and so forth.
