Why each option
NMAP is the industry-standard tool for network discovery and vulnerability scanning, allowing administrators to identify open ports and services.
ICMP is a network layer protocol used for diagnostics like ping; it is not a scanning tool.
NMAP (Network Mapper) performs host discovery, port scanning, service version detection, and OS fingerprinting across a network. Security administrators use it to identify exposed services and potential vulnerabilities on networked devices. It is purpose-built for the network reconnaissance needed in vulnerability assessments.
ACL (Access Control List) is a security filtering mechanism, not a tool for scanning or discovering vulnerabilities.
TCPDUMP is a packet capture tool used to analyze network traffic, not to scan for vulnerabilities.
