Or, for instance, if an attacker tries to connect to port 3389 for Windows Remote Desktop to gain control of a server, the firewall will block the connection. So, if an employee incorrectly tries to use FTP on port 21 instead of SFTP, it will be blocked. It forwards these ports to the specific servers for each type of service. Its firewall would allow inbound connections to ports 80 and 443 for web traffic, port 25 for inbound email and port 22 for Secure Shell FTP ( SFTP). They are configured to only allow communication to the specific ports needed for a service and block other unneeded ports so they cannot be exploited.Īs an example of ports in use, say a company wants to have a website, email and secure file transfer service on the internet. Attackers can use this to find vulnerable services that they can then attack.įirewalls take the port number into consideration when determining to allow or block communication. Port scanning, for example, tries all ports at an address to see which ones are open and listening. Network ports are a major factor in network security and cybersecurity in general. How do network ports affect cybersecurity? Port forwarding is when communication to one address on a specific port is then sent, or forwarded, to another computer for processing. A listening port is when the computer is actively waiting for inbound requests on that port number, allowing those connections. This is because the local IP address, local port, remote IP address and remote port specify each connection. The port is specified by having the URL or IP address followed by a colon then the port number - as examples, 10.0.0.1:80 or With all internet communication, there is always an associated port, but it may not be shown to the user as it is often implied by the type of communication.Ī computer can manage many simultaneous connections on a single inbound port. Generally, this is with Transmission Control Protocol or User Datagram Protocol for communication, but Internet Control Message Protocol messages use specific ports as well. Port numbers identify specific applications or services on a computer system, just like an IP address identifies a machine in an IP network and ascertains the destination of a data packet.Ī port is always associated with a protocol. Dialing extension 0 to speak to an operator is extremely common in all phone systems and is like the well-known ports that always define specific services. A telephone extension will connect them with the right person in an organization, however, and the port will connect them to the right service on a computer. It connects users with the correct company but does not define who they want to talk to in the company. The company telephone number is like the computer Internet Protocol (IP) address or Uniform Resource Locator (URL). The numbers 49152 to 65535 are unassigned, can be used by any type of service and are called dynamic ports, private ports or ephemeral ports.Īs an illustration, think of a port number as a telephone extension in a business telephone system. The numbers from 1024 to 49151 are called registered ports and can be registered with the Internet Assigned Numbers Authority for a specific use.
These are called well-known ports and go from 0 to 1023. Some of these port numbers are specifically defined and always associated with a specific type of service - for example, File Transfer Protocol ( FTP) is always port number 21 and Hypertext Transfer Protocol web traffic is always port 80. The numbers go from 0 to 65535, which is a 16- bit number.

A port in computer software is when a piece of software has been translated or converted to run on different hardware or operating system ( OS) than it was originally designed for.Ī port in computer networking is how a computer can use a single physical network connection to handle many incoming and outgoing requests by assigning a port number to each.A port in computer hardware is a jack or socket that peripheral hardware plugs into.A port in networking is a software-defined number associated to a network protocol that receives or transmits communication for a specific service.
A port in computing has three main uses, each as a type of receptacle in networking, computer hardware and software:
