But, if it responds with a UDP packet, the port is open. If an ICMP unreachable error comes back, the port is closed. UDP scans are done by sending UDP packets to all ports. They are slower and more complex to send than a SYN or TCP packet but can be combined with those types of scans to check UDP ports. Instead of running over TCP, hackers can deploy User Datagram Protocol ( UDP) scans over domain name system, Dynamic Host Configuration Protocol or Simple Network Management Protocol. Instead of requiring a raw packet like other scan types, Nmap will request a connection with the target operating system (OS) using a system call. A TCP scan is common for users who don't have raw packet access privileges, but it is less efficient than a SYN scan. If a SYN scan can't be performed, a TCP connect scan is a popular alternative for hackers. 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. If no response is received or if an Internet Control Message Protocol ( ICMP) unreachable error is received, it indicates a filtered state. A SYN/ACK response indicates an open TCP port, whereas an RST response indicates a closed port. It works by sending a SYN packet in an attempt to open a connection. For this reason, TCP SYN scanning is also commonly referred to as half-open scanning and can indicate open, filtered and closed port states.

It is a quick and efficient scan, not restricted by firewalls since it never completes the full TCP connection. The TCP SYN scan - a variant of the traditional SYN scan - is commonly used. The following is a list of some scan types that can be done by a port scanner. What results is that few or no communications from legitimate clients can take place.Īs part of a extensive network security program, it's important to understand that other port scanning techniques can be used in conjunction with SYN scanning or as a substitute for it. When a hacker continuously sends large numbers of SYN packets to a server, it can consume server resources. If the server responds with an RST packet from a particular port, it indicates that the port is closed and cannot be exploited. The open port remains open and vulnerable to exploitation. In this scenario, the assumption is wrong. Then, the hostile client sends an RST (reset) packet.Īs a result, the server assumes that there's been a communications error and the client has not established a connection. If the server replies with an ACK (acknowledgement) response - or SYN/ACK (synchronization acknowledged) packet - from a particular port, it means the port is open. This is done by sending a SYN (synchronization) packet, as if to initiate a three-way handshake, to every port on the server. In SYN scanning, similar to port scanning, the threat actor attempts to set up a Transmission Control Protocol/Internet Protocol ( TCP/IP) connection with a server at every possible port.
