A security plan is required to own and operate a company network. If your network has a security problem, it can spread to any device that is linked to your network. Your business needs to address threats from numerous sides in order to safeguard both your network and your devices. One corner that many companies don’t consider is malware that has already invaded your network and is waiting for the appropriate time to strike. That’s where a solution for network detection and response (NDR) comes in.

NDR is a relatively recent technology, which developed as an off-shoot of EDR that applied its essential values to networks — hence network detection and response. True to its name, NDR solutions identify and respond to security risks on a network. Why should you employ a Sangfor network detection and response solution, and what is NDR’s failure to provide other security tools?

Detection and Response Network Defined:

Network Detection and response is a progressive security solution for the full visibility of both known and undiscovered network threats. NDR offers centralized, machine-based network traffic analysis and response solutions, including effective workflows and automation.

You might ask why your team cannot just employ traditional security solutions such as IDS/IPS for your network security strategy. Sadly, security teams cannot rely on signature-based security techniques to identify network security issues requiring further analysis. New attacks cannot be detected by signature-based security systems unless signatures have been previously written to recognize network assaults. These older techniques do not establish linkages or examine data in time to recognize potential dangers in many data points. In addition, they do not offer much responsiveness.

What has been the development of network detection and response?

Network traffic monitoring is not a new practice. Initially, network metadata was collected to analyze network performance. Is our network all right? However, as the volume of data increased, many companies were unable to use network activity as an untapped resource for cyber defense.

Computer power eventually caught up, offering companies traffic visibility and computer safety tools for behavioral analysis – a technology called network traffic analysis (NTA). And although NTA remains a corporate security center (SOCs) feature, the market category has grown and expanded to include network detection and response. Organizations increasingly appreciate the responsive capacity of NDR solutions to address threats from network traffic analysis tools, which largely focus on threats to detection and mostly fundamental deviations from recognized dangers.

How does network detection and response function?

NDR continually absorbs and correlates enormous volumes of network traffic and safety events over several assets and hops. Collecting information from a network perimeter (to cover North-South traffic), network sensors (to cover Eastern-West traffic), NDR solutions leverage AI and machine learning for the development of a basic understanding of normal network traffic flows, and thus the detection of malicious activities which do not follow normal patterns.

AI-driven NDR tools are continuously learned and adapted to automatically detect advanced threats that are constantly changing.

If an attack is detected, NDR solutions can perform end-to-end forensic analysis of the attack chronology from initial infiltration to lateral network movement, which can activate workflows for prevention and mitigation automatically.

Malicious Networks – Early Days Action

Before broad internet use, network abnormalities occurred, but until the 1990s they did not cause considerable impact. This is when more companies started deploying web servers, desktop operating systems, and other technologies which became explicit malware objectives. Attackers now have been able to detect weaknesses within these programs and create malicious malware to exploit them.

Free Network Monitoring Software Types:

There are three primary types of tools on the market for free network monitoring:

  • Commercial tools that are always free
  • Open source tools that are always free
  • free tools with further cost and value upgrades

Let’s go through each form of freeware’s perks and downsides below.

Business Tools: Still Free

These tools are designed to meet the IT demands of companies and are 100% free. Sometimes ads are displayed in the UI. Basic functionality such as automatic network detection, supervision, and alarm are commonly available.

Benefits: You’ll enjoy all your features at a fantastic price if you can find a freeware solution that does exactly what you require. A better ROI can’t be asked!

Disadvantages: The problem of utilizing an ever-free tool is that you may lack critical functions. And what you get with always-free tools is what you get. There is no upgrade or addition of any additional features – so be sure you are content with the product as it is before you roll it out. Another concern is that the product will not provide you with the same stability or reliability as a premium tool.

Open Source Tools: Still Free

If you have any specific requirements, try an open-source freeware monitoring solution. Advantages: the most important advantage of open source software is that it provides you with flexibility. You may adapt the software to accomplish exactly what you need if you are a developer or programmer and know how to code.

Disadvantages: Open source tools can take a considerable amount of development time and cost to get them where they are. With the required skills and setup, what begins as a “free” solution might not really be free in the end due to the time and effort needed. They rarely give support resources, however, so if anything goes wrong, you’ll be on your own.

Business Tools: Free to get started:

Many programs give the possibility to add more monitoring, support, or additional features at a cost for a limited software version free of charge.

Benefits: Starting with freeware enables you to ensure that the product complies with your IT standards. Any software that provides both free and paid versions for network monitoring usually has a solid market reputation and resume. Even if your boss claims there is no money to spend on a premium product, it’s easy to upgrade if you want to later when it realizes the value that the tool provides.

Disadvantages: Products with a free model can usually only be used to monitor a fixed number of devices or sensors. This is why it is ideal if just modest IT environments with limited equipment are monitored. The level of technical help they provide also differs. While it is impossible to anticipate the same amount of support from a product for which you do not pay, it is crucial to know from the start what sort of resources you will have access to.
