  • The growing fear of malware injections and infiltration into networks.

The perfect solution to master these and many other challenges is a network discovery tool.

Frequently Asked Questions

Q #1) How do network discovery tools work?

Answer: It uses a specific set of protocols, such as SNMP (Simple Network Management Protocol) to scan the IP addresses of connected devices. The SNMP protocol uses a polling method to identify connected devices.

Q #2) What is passive scanning in networking?

Answer: Passive scanning is an indirect method of communication that collects network data available on the network without sending a direct ping request. Since the passive scan function is limited to the currently available traffic data, it does not have complete accuracy because the device cannot detect it when it is turned off.

Q #3) What is network inventory?

Answer: Network inventory is the list of connected devices in the network, like desktops, laptops, servers, routers, switches, printers, and so on.

Q #4) What is a network discovery scan?

Answer: Network discovery scan is a method that scans various IP addresses to find known and unknown devices and their open ports. This is considered the first step in evaluating network administration security.

Q #5) What is a network discovery tool?

Answer: This tool helps IT professionals find connected devices on a network, making it easier for them to manage their network and devices.

Q #6) How do I setup network discovery

Answer: For setting up network discovery in Windows operating system, search for the “Network and Sharing Center” option ->  Select Change advanced sharing settings-> Select the “Turn on network discovery” option and save changes.
