What is a Xmas scan used for?
An adversary uses a TCP XMAS scan to determine if ports are closed on the target machine. This scan type is accomplished by sending TCP segments with all possible flags set in the packet header, generating packets that are illegal based on RFC 793.
How does a SYN scan work?
TCP SYN scan It works by sending a SYN packet in an attempt to open a connection. A SYN/ACK response indicates an open TCP port, whereas an RST response indicates a closed port. On rare occasions, a SYN packet may be returned without the ACK flag, indicating an open port and the presence of a TCP three-way handshake.
What is Nmap flag?
Nmap flags are the parameters we use after calling the program, for example -Pn (no ping) is the flag or parameter to prevent nmap from pinging targets. Below you’ll find nmap’s main flags with examples. –exclude: This flag is useful to exclude IP addresses or hosts from scans when we scan IP ranges or target files.
How do I scan a UDP port?
Fortunately, Nmap can help inventory UDP ports. UDP scan is activated with the -sU option. It can be combined with a TCP scan type such as SYN scan ( -sS ) to check both protocols during the same run. UDP scan works by sending a UDP packet to every targeted port.
What is a Xmas packet?
In information technology, a Christmas tree packet is a packet with every single option set for whatever protocol is in use.
When would you use a SYN scan?
SYN scanning is a tactic that a malicious hacker can use to determine the state of a communications port without establishing a full connection. This approach, one of the oldest in the repertoire of hackers, is sometimes used to perform a denial-of-service (DoS) attack. SYN scanning is also known as half-open scanning.
How did TCP Maimon scan get its name?
TCP Maimon Scan (-sM) The Maimon scan is named after its discoverer, Uriel Maimon. He described the technique in Phrack Magazine issue #49 (November 1996). Nmap, which included this technique, was released two issues later.
What is the Nmap flag for a Maimon scan?
The Nmap flag for a Maimon scan is -sM. While this option was quite useful in 1996, modern systems rarely exhibit this bug. They send a RST back for all ports, making every port appear closed. This result is shown in Example 5.18.
Who was Salomon Maimon and what did he do?

Is the Nmap scan the same as null, fin and Xmas?
Nmap, which included this technique, was released two issues later. This technique is exactly the same as NULL, FIN, and Xmas scan, except that the probe is FIN/ACK. According to RFC 793 (TCP), a RST packet should be generated in response to such a probe whether the port is open or closed.
