The status of a port (open or closed) can usually be controlled through a network firewall. When a port is closed, all the traffic specific to that port is blocked, preventing it from entering the local network.

When a port is open, data packets are permitted to flow in and out of your local network through that port. TCP Port scanners can also help penetration testers determine which specific ports are accepting data so that they can be protected from compromise. For maximum security, all free port scanners should be supported with additional security solutions.

This is why free open port scanners should only be used by network administrators to determine the level of network visibility available to potential cyber attackers. So they cannot be the only security controls protecting your network. Port scanners are also used by cybercriminals to garnish vulnerability intelligence about a potential victim before launching a cyberattack.īecause many of these tools are freely accessible, you must assume that cybercriminals are using them to study your open ports. Such network reconnaissance should be completed regularly to identify and remediate vulnerabilities before they're discovered by cyberattackers. It involves identifying open ports and also sending data packets to select ports on a host to identify any vulnerabilities in received data. Port scanning is the process of analyzing the security of all ports in a network.
