Final answer:
IDS, NIDS, and Honeypot are the systems that respond to ping, network topology, and potentially the location of additional firewalls.
Step-by-step explanation:
The systems that respond to ping, network topology, and potentially the location of additional firewalls are IDS (Intrusion Detection System), NIDS (Network Intrusion Detection System), and Honeypot.
An IDS is a security tool that monitors network traffic for suspicious activity and alerts administrators. It can respond to ping requests, detect changes in network topology, and identify the presence of additional firewalls.
A NIDS is specifically designed to monitor network traffic and identify suspicious activity. It can respond to ping requests, analyse network topology, and detect the presence of additional firewalls.
A Honeypot is a decoy system used to attract and monitor potential attackers. It can respond to ping requests, analyze network topology, and identify the location of additional firewalls.
