Which of the following will record web sites visited and web applications used for incident response analysis?

Squid maintains detailed access logs of every HTTP and HTTPS request routed through it, capturing URLs, timestamps, client IP addresses, and user agents. These logs allow incident responders to reconstruct browsing history and identify malicious web application usage on compromised hosts. No other tool in the list is designed to record application-layer web activity at the proxy level.

Berkeley Packet Filter is a kernel-level mechanism for filtering raw network packets and does not record or interpret application-layer web browsing history.

Netcat is a general-purpose TCP/UDP utility for reading and writing raw data across network connections and has no capability to log or record web activity.

Netscan is a network discovery and port scanning tool used to enumerate hosts and services, not to record web browsing or application usage.
