Definition
Network discovery is the process of detecting and mapping devices, services, or resources within a network. It helps network administrators understand the network layout, manage connected devices, and troubleshoot network-related issues.
Network discovery can also be defined as the ability of network devices to find and connect with each other.
Network Discovery Working Mechanism
- A network discovery tool (eg, Nmap) scans the network to identify active devices, resources, or services.
- Each device has a unique identification, such as a hostname or IP address.
- The tool collects and logs information about each device, such as its open ports or operating system.
- The detected devices and their relationships are mapped out to understand the network’s layout.
- The network administrators receive the scan results in an easy-to-read format, enabling them to analyze the information and manage the network effectively.
Network Discovery and Security
- Network admins can use network discovery to monitor changes and identify potential security threats.
- Network discovery helps to detect security issues in devices.
- Network discovery helps to keep the network inventory up to date.
- In case of a security incident, network discovery can help to detect affected devices and allow admins to respond quickly.
