Checking listening ports is a crucial aspect of network security and troubleshooting, as it allows network administrators and users to identify which ports are open and accepting incoming connections on a computer or server. Open ports can be used by both legitimate applications and malicious actors to establish network connections, making it important to be aware of which ports are listening and to take appropriate security measures.
There are several methods for checking listening ports, including using the netstat command on Windows and Linux systems, or using third-party software applications designed for port scanning. By regularly checking listening ports and monitoring network traffic, organizations and individuals can help to identify and mitigate potential security risks and ensure the integrity of their networks.
