In some cases, TCP packets in FIN location I are able to bypass older firewalls, thanks to the nature of TCP, and if the system receives such a TCP packet and the corresponding port is not open, it will reply with a TCP packet in RST location I. UDP scanning: Because UDP is a connectionless protocol, there is no TCP like three handshakes, so the UDP scanning tool must rely on ICMP "port unreachable" messages to determine whether the relevant port is open. When the scanning tool sends a UDP packet and the target system is not listening to the corresponding UDP port, it replies with an ICMP "port unreachable" message. This type of scan is subject to firewall and ICMP rate limits.Strobe scans: Attackers typically perform these scans to discover vulnerable ports, and the attacker knows how toExploit such vulnerabilities. Strobe scans are performed at a more precise range. Stealth scan: a scan that is undetectable by network auditing tools. Example 13-1 shows a standard port scan performed with Nmap on a Linux host ( 172.18.104.139).Example 13-1 Example of the Nmap scan toolbash-3.2$ sudo nmap -sS 172.18.104.139 Password, **************** StartingNmap7.12(https://nmap.org)at
