The NULL, FIN, and Xmas scans clear the SYN bit and thus fly right through those rules. Another advantage is that these scan types are a little more stealthy than even a SYN scan. Don't count on this though—most modern IDS products can be configured to detect them.

What is Nmap’s NULL scan? Nmap’s NULL scan is a type of scan that uses the TCP protocol with no flags set in the header of the packets. This scan can evade firewalls or intrusion detection systems that only look for certain flag combinations because the NULL scan packets don’t have any flags set.
13 Δεκ 2023 · Vulnerability Scanning: Nmap can be used in conjunction with vulnerability databases and scripts (such as NSE scripts) to scan for known vulnerabilities on devices. This aids in proactive security measures to patch or mitigate vulnerabilities before they are exploited.
2 Οκτ 2020 · During security auditing and vulnerability scanning, you can use Nmap to attack systems using existing scripts from the Nmap Scripting Engine. Nmap has a graphical user interface called Zenmap. It helps you develop visual mappings of a network for better usability and reporting.
15 Μαρ 2024 · Nmap, an influential and versatile Network Mapper, is the network reconnaissance and vulnerability detection go-to tool. As you begin your journey in ethical hacking or work towards developing your penetration testing skills, it is imperative to learn the key Nmap commands.
9 Φεβ 2021 · In an idle scan, Nmap doesn’t send the packets from your real IP address — instead of generating the packets from the attacker machine, Nmap uses another host from the target network to send the packets. Let’s consider an example to understand the concept of idle scan: nmap -sI zombie_host target_host # nmap -sI 192.168.1.6 192.168.1.1
