open ports

Network security is a pivotal aspect of IT management, ensuring that unauthorized access points within network interfaces are minimised or eliminated. For system administrators and security professionals, one of the most crucial tasks is managing and monitoring open ports on a computer or network device. Open ports can serve as gateways for attackers to enter or extract data, making the task of checking them a necessity for maintaining system security. One of the most effective tools for monitoring network connections and open ports is netstat, a versatile network utility tool available in Unix-like systems as well as in Windows.
