A security analyst needs to quickly identify all active hosts and their open web server ports (80, 443) on a specific subnet. The analyst requires a tool that actively probes each IP address to elicit a direct response for rapid asset discovery. Which of the following tools is BEST suited for this task?
The correct answer is Angry IP Scanner. It is a network scanning tool specifically designed for fast, active scanning of IP ranges and ports. It operates by sending probes, such as pings or connection requests, to each IP address and analyzing the responses, which directly aligns with the analyst's requirement for an active scanning tool. Wireshark and tcpdump are packet sniffers used for passive network traffic analysis, not active probing. Prowler is a specialized tool for assessing cloud security and is not the appropriate choice for a general subnet scan.
