Device discovery utility windows 7




















Network devices are not managed as standard endpoints, as Defender for Endpoint doesn't have a sensor built into the network devices themselves. These types of devices require an agentless approach where a remote scan will obtain the necessary information from the devices. To do this, a designated Microsoft Defender for Endpoint device will be used on each network segment to perform periodic authenticated scans of preconfigured network devices. For more information, see Network devices.

Corelight : Microsoft has partnered with Corelight to receive data from Corelight network appliances. This provides Microsoft Defender with increased visibility into the network activities of unmanaged devices, including communication with other unmanaged devices or external networks. Vulnerabilities and risks on your devices as well as other discovered unmanaged devices in the network are part of the current TVM flows under "Security Recommendations" and represented in entity pages across the portal.

Search for "SSH" related security recommendations to find SSH vulnerabilities that are related for unmanaged and managed devices. You can use Advanced Hunting queries to gain visibility on discovered devices. Find details about discovered Endpoints in the DeviceInfo table, or network-related information about those devices in the DeviceNetworkInfo table. Device discovery leverages Microsoft Defender for Endpoint onboarded devices as a network data source to attribute activities to non-onboarded devices.

This means that if a Microsoft Defender for Endpoint onboarded device communicated with a non-onboarded device, activities on the non-onboarded device can be seen on the timeline and through the Advanced hunting DeviceNetworkEvents table. The following section lists the changes you'll observe in Microsoft Defender for Endpoint and Microsoft Defender portal when this capability is enabled.

With all sites enrolled, the manager can see an overview of the entire system and then focus in on each site and then down to each individual endpoint. The software inventory can also be consolidated per site, which enables functions such as software license management.

The package includes utilities for manual access and also automated maintenance services. Among the automated services is a patch manager. This maintains the software inventory and keeps checks on the suppliers of the operating systems and software packages listed in it, looking for the availability of updates.

When patches become available, the Syxsense Manager service copies them over to its own storage space. A Syxsense Manage package includes 50 GB of cloud storage. The Syxsense Manage package is a subscription service with the lowest bundle monitoring 10 devices.

This is charged annually in advance. You can assess the service with a day free trial. Paessler PRTG is a combined network device monitor, traffic analyzer, and server status manager. This will keep track of the health and performance of all of your network hardware and supporting devices.

The server status monitoring extends to Cloud storage and online application services. Application transaction and resource utilization are also covered, and the monitor extends to the tracking of database transactions that server application execution. PRTG will also cover virtual environments and wifi elements in your network.

All of those different types of services take a lot of tracking, and it can be challenging to conceptualize all of the interfaces between different types of systems. The software installs itself, and one of the setup steps is a network discovery scanning phase that will document and list all of these different types of devices and how they work together. You can opt for an online version of the system, but that still needs an agent to be installed on your system.

The PRTG dashboard can assemble maps that represent all of the different elements of your network. You can access maps that show virtualization , wifi performance , VoIP traffic , general network performance by link and end-to-end , and connections over the internet through to the operations of network links and server performance owned and managed by other companies.

Any potential problems arising in any part of the system get reported to the console immediately. Those alerts can be customized , so you can specify your combination of errors and warnings that would make you sit up and take notice, rather than getting notified about low ink toner levels or other non-critical maintenance conditions.

While all of this monitoring is going on, the network discovery process keeps you in the loop. So, any outages or performance problems get reflected on your various network maps. The PRTG system can be accessed as a Cloud service , or it can be installed on premises — the software will run on Windows 10 and Server environments.

The system is available for free to monitor small networks. You can also get a day free trial of PRTG. You will encounter two types of Nagios monitoring software. The one you need to consider is Nagios XI. Nagios Core is a free, open-source network management tool.

There is a Nagios Community made up of Nagios users and you can get interfaces for Nagios Core in the community forum for free from some of those users. However, Nagios XI is Nagios Core with a professional interface included , so you are better off going for that version. The Nagios XI suite includes an autodiscovery module that will map all of your network for you and compile an inventory list.

This means that you can review periods of network congestion and watch as bottlenecks appear. This is an excellent tool for analyzing the system weaknesses because you can examine events over and over again, making sure that you understand exactly what happened.

The monitor will observe and record the status of your network equipment and you will see alerts when failure and warning conditions occur.

In addition to showing alerts in the Dashboards, you can get Nagios to notify team members by email or SMS. Those alerts can be directed to different team members according to source and severity. The Dashboard can also be customized, which means that you can give access to different views and controls to different team members.

The Dashboard widgets include dials, graphs, histograms, and charts that make data easier to view. There is a free version of Nagios XI. This is capable of monitoring small networks. Free Nagios XI is limited to monitoring just seven pieces of equipment. The paid version of the system is available in a Standard Edition and a more expensive Enterprise Edition depending on the size of your network. Related post: Nagios vs Zabbix.

A significant advantage of the SNMP methodology is that it has network discovery software built-in. This is because all network devices have SNMP agents installed on them, so any monitoring program just has to broadcast a report request on the network to receive notifications from all of the network equipment. This enables an initial network device inventory to be compiled.

The polling process of SNMP is re-issued periodically. That means that the equipment list is continuously updated. So, if you add or remove a device, those changes get registered in the inventory automatically.

Cacti is a free, open-source system that was created to provide a front end to the data gathering RDDTools. So, you need to install both of these systems to get network discovery and monitoring.

The RDDTool system is also open source and free to use. The Cacti package includes a set of graph templates. You can customize a user interface by selecting a subset of the graph template pack. You can also create multiple user accounts and assign different sets of graphs to each. The free tool is useful for allowing users to see their own service consumption in leased service scenarios, SaaS provision, storage services, and even internet service provision.

The package includes a live network monitoring system that is based on SNMP. As SNMP performs regular status polling by broadcasting a report request, it automatically discovers all network devices. Network devices are shipped from the manufacturer with an SNMP agent installed and that agent is programmed to constantly listen for a status request.

Any device out on the network will automatically respond to the status request and these answers inform the network monitor of exactly what devices are out there on the network. The first time the status request and response cycle runs NinjaRMM collates an asset inventory database. In that case, the new device gets added to the inventory.

The network discovery tool is just one of the features of the NinjaRMM system. The dashboard also gives access to live traffic flow data with alerts when devices get overloaded.

Other features include Syslog monitoring, patch management, and a managed antivirus service. The NinjaRMM is a cloud-based service and is charged for by subscription with a rate per device.

You can a day free trial of NinjaRMM to experience the network discovery feature on any site. Zenmap is a graphical front end to Nmap.

Both Zenmap and Nmap are free to use. Nmap is a security auditing tool , but it can be used for network scanning. Details of each node include the operating system, manufacturer, device type, IP address, hostname, and the status of the ports on the device.

However, Nmap has a huge following and the combination of Zenmap and Nmap is widely distributed. These tools will be of use to you to provide ad-hoc system scans and security checks. Spiceworks produces a suite of network monitoring tools that can be installed on premises or accessed online.

All of the Spiceworks tools are free but ad-supported. ITo get all of your devices logged, you will need to use the Spiceworks Inventory module. The Inventory tool will search your system and log all of the equipment connected to your network. Not only will it register each piece of equipment, but the facility also gives you operational details of each device. The scan will also log all of the software that you have available.

The Inventory tool will keep all of your software up-to-date with the latest versions and install patches when they become available. You will also be able to see which applications are overloading the network and watch data flows that result in service bottlenecks. You can enhance the visibility of data and switch from list views over to a graphical representation of the network by installing the Spiceworks Network Mapper.

This tool uses the information registered by Spiceworks Inventory , so you need that research tool installed before the mapper will work. You will see traffic volumes on the links between devices represented as the thickness of the line representing the link.

The map covers Layer 2 switches and Layer 3 routers devices. The device icons in the map act as links to detail pages, where you can see the status and operating methods of each piece of equipment. You can generate reports out of the Inventory system that will list devices by type or you can print out graphs of usage. Server details cover disc volumes and usage , memory availability , and CPU use.

Other features of the Inventory package link to the Spiceworks Help Desk module. These include the user details for each endpoint and links to your Active Directory implementation to help you manage user authorization. The Inventory system reaches out to other branches of your system to help you inform and monitor all stakeholders.

NetBrain has an excellent network discovery procedure. The software is accessible online but it can penetrate your network to build an inventory of devices. You enter the IP address of a key router on your network, and the NetBrain system crawls out from there to record all of your network devices. The next phase of installation is the automatic creation of a network map.

The map provides the interface for other functions available with the NetBrain package. The network discovery feature of NetBrain keeps monitoring your system and updates automatically when you add or remove devices. The system will log Layer 2 and Layer 3 devices and help you manage their configurations. The Configuration Management tool in NetBrain alerts for unauthorized changes and also keeps the firmware of your network equipment up to date.
