Lansweeper tutorial on Passive Scanning, Asset Radar, and our Device Recognition technology to automatically detect and identify new assets on the network. Read the full blogpost ► www.lansweeper...
What is Passive Scanning?
Passive scanning is a method of network analysis that does not require active communication between two systems. From a Lansweeper perspective this means that instead of going out and gathering information, we just listen and capture whatever information gets presented.
What is Asset Radar?
Asset radar is our implementation of passive scanning. Asset radar can be enabled on any Lansweeper server to passively listen to the network on a selected network interface to get IP addresses, MAC addresses and more.
What is Device Recognition?
Device recognition is a technology Lansweeper uses to enrich data found in your IT environment. By taking combining specific data points like MAC address, Protocol, and MessageType we generate a unique device fingerprint that gets enriched by our device catalog, a massive data lake with device properties and identifiers.
What is Credential Free Device Recognition (CDR)?
CDR is the combination of asset radar and device recognition to create what we call Credential free Device Recognition. It uses the passive scanning from asset radar to gather data on devices in your network and passes that data on to device recognition which uses the data points to create a device fingerprint which is used to further enrich the data from our device catalog.
CDR has options to either just log info of assets detected, or pass them on to active scanning for a full scan and asset creation.
Why Use CDR?
Now let's get to the why. CDR will give you a great view of what has been happening in your network in real-time, it also logs activity for however long you want (depending on what you configure). So it's ideal to use in wireless networks so you have a log of which devices have connected and if you want to scan them.
Do you want this information without creating more assets? No problem, CDR lets you enabled log-only mode which only logs the devices in your network, and doesn’t pass them on to active scanning to get scanned. This way you still know what has been connecting without any assets being created.
Other use cases like discovering shadow IT, or rogue device detection are also great use cases for CDR. In essence, anything that could benefit from a listening ear on a subnet can utilize CDR.
