Practical Cyber Hacking Skills for Beginners - Host Discovery Controls

The video tutorial explains how Nmap uses different probes to discover active hosts on a network. It covers the four main types of packets used by Nmap: ICMP echo request, TCP SYN, TCP ACK, and ICMP timestamp request. The tutorial also discusses host discovery controls and the default information Nmap seeks, such as IP addresses and open ports. It highlights the challenges of intrusive scans and introduces stealth scanning techniques like the least scan and disable port scan. Finally, it explains the disable ping scan, which skips host discovery to directly scan ports, useful for network administrators testing security systems.
