Network Traffic Monitoring: Why Network Admins Need Network Traffic Analyzer?

In order to assess, analyze, and manage network traffic for any anomalies, network performance management aids in network traffic monitoring. The activity that may impact network performance, availability, and/or security is network traffic analysis. Network traffic monitor analyzes the network-based traffic on your computer using a variety of tools and methods.

It happens frequently that networks' overall speed decreases as they become crowded. The IT infrastructure is undergoing a number of various developments, such as a growth in the usage of cloud servers, video, VOIP, etc. These changes place a great deal of strain on the infrastructure resources for IT. Companies frequently use network monitoring software to track network traffic when a network is under more strain than usual.

The procedure is not only expensive, but it also has a relatively limited shelf life. The infrastructure will eventually experience the same problems it did before the upgrade if you provide the network with additional IT infrastructure resources without attempting to reduce the burden.

The NetFlow analyzers are the greatest tool for determining the kind of network traffic and its source. Generally speaking, NetFlow is a capability that was originally made available in Cisco hardware. It can gather IP-based network traffic by keeping an eye on data input and outflow. It aids the administrator in monitoring the origin and destination of traffic, the type of service provided, and the causes of congestion.

Why Network Admin Needs Network Traffic Monitoring

There are a number of valid reasons to keep an eye on network traffic in general. There are several operational and security use cases for the data generated by network traffic monitoring solutions. For instance, to identify security flaws, troubleshoot network-related problems, and assess how new applications may affect the network as a whole.

A key point to remember in this respect is that not all instruments for monitoring network traffic are created equal. They may often be split into Deep packet inspection tools and flow-based tools, two main categories. You can choose from tools within these two categories that don't require software agents. Additionally, they want to save historical information and tools with intrusion detection systems that keep an eye on network activity both within the network and at its boundary.

1. Internal network visibility is first

Complete visibility of internal network traffic is possible with network flow monitoring software that supports protocols like NetFlow, IPFix, JFlow, sFlow, etc. The IT department may provide meaningful reports regarding the following traffic types and types using Motadata.

Applications with the most traffic, conversations with the most traffic, traffic destinations with host IP addresses, IP to IP traffic, protocol traffic, port traffic, and applications with the most traffic

2. Recognizing delayed apps

The user experience is greatly influenced by speed, often known as performance. Application (web application, Go-to-Meeting, Skype, etc.) slowness or crashes are one of the most common help desk tickets. There may be hundreds of causes, but only one or two of them will be important at any one time. Finding the cause is not only time-consuming but also expensive. The accurate cause can be filtered and reported by the next-generation Netflow software. The system administrator may discover a lot about the system and the broken network by integrating the internal data reports and outside resources.

3. Finding spyware and other types of hacks

These worms create a highly odd inbound and outbound data flow when they assault your network. These strange patterns are simple to find with Netflow. These patterns frequently go unnoticed if you are not utilizing a data analyzer since they are created to deceive the human administrator.

The majority of these worms frequently result in non-financial issues by damaging the company's reputation. However, these worms can also cause a significant financial loss in specific circumstances.

4. Identification of the outflow of customer personal information

This argument is particularly relevant to businesses involved in the payment gateway or credit card industries. A reliable payment gateway will never allow a client's private information to leave its network. Such information may start to flow out in a specific way, which the Netflow program immediately reports.

5. Use of departmental bandwidth

Netflow might be useful if you're concerned about how the network is being used generally and are unable to determine which department is using the data flow the most heavily. It can keep track of and identify IP addresses and other devices consuming network resources. The administrator can then take the appropriate steps to lessen the strain on the network.

The Motadata platform supports the prominent and extensively used protocols Netflow (versions: v5, v9), IPFix, sFlow, and JFlow.
