In this video, Marc Menninger describes how to conduct network discovery to find testing targets. Learn about the differences between passive and active network discovery and watch demonstrations of tools to perform different forms of discovery.
- Network discovery is the first step…in target identification and analysis.…It's the process of determining which network devices…exist within the in-scope address ranges…of the security assessment.…This step is also referred to as reconnaissance,…or device enumeration.…There are two forms of network discovery,…active and passive.…In active network discovery,…software sends various types of network packets…to probe for other network devices.…
For instance, the network discovery software…can send an internet control message protocol,…or ISMP, echo request, or ping,…to all network addresses in a range.…Active devices should respond to a ping…with an echo reply.…Ping sweeps such as this are often the first step…in active network discovery.…Conversely, passive network discovery…is another way to find network devices…without sending any packets.…
Network sniffing tools, like Wireshark,…can be used to capture and analyze…network traffic to find the IP addresses,…open ports, and operating systems of devices…which are active.…
