The larger the amount of data, the more reliable will be the information provided by the network traffic analyzer. However, this does not mean that common tools are reserved only for large organizations: Even in a small company, you can accomplish a lot by monitoring network traffic. After all, a small-scale environment also has its advantages – especially because it is easier to perform a network traffic check. The following data will help you to get a comprehensive view of your network traffic. 1. Network data sources Such data sources are the first step to effectively monitor network traffic. The goal here is to achieve the highest possible transparency. This first data source almost always requires you to unify data from different sources. Therefore, it makes sense to rely on professional network traffic monitoring tools at this point. 2. Flowdata Analyzing moving data gives you a comprehensive insight into your network’s performance. If you are working with many domains or different providers, this analysis is especially important. 3. Packet data For forensic analysis, you need not only bandwidth monitoring, but also packet data.

Read Disclosure Network analysis, or the process of “looking” at network traffic and trying to understand it, is a complex endeavour. It is, however, a very useful process as it can provide precious assistance when troubleshooting various networking issues. It is also one of the best tools for capacity planning. But let’s face it, it is something that is best left to computers to handle. This is why we’re about to review some of the best network analysis tools. Our hope is that our reviews of the top product can help you compare what is available and select the product—or products—that best matches your specific needs.We’ll begin our journey by having a deeper look at network analysis, exploring what it is and how it’s done. Then, we’ll explain the differences between the two main types of analysis, quantitative (i.e. bandwidth analysis) and qualitative (i.e. flow analysis). Our next order of business will be a short explanation of the Simple Network Management Protocol as it is the most-used technology for bandwidth analysis followed by a similar exploration of the NetFlow technology, the most common flow analysis method. We’ll finish with the best, our brief reviews of the best bandwidth analysis and the best flow analysis tools.Network traffic is often compared to road traffic where network circuits can be thought of as highways and the data packets they transport are compared to the vehicles travelling along them. But while automobile traffic is visible and any problem or congestion is readily observable, seeing what’s going on within a network can be a bit more complex. Network traffic is hidden within networking devices, copper cables or glass fibres and it travels at the speed of light; way too fast for anyone to see it.To effectively analyze network traffic, specialized tools must be used. Some can poll devices to get their interfaces’ traffic figures and to show you how much data travels through them. Other tools, as we’re about to find out, use a different approach to get details about individual data flows and build reports that not only show how much data goes by but also what that data is, where it’s coming from and where it’s going to.Quantitative vs Qualitative AnalysisNetwork bandwidth analysis is the most basic type of network analysis. Specialized analysis tools can measure how much data is transported on each router interface. They typically rely on the Simple Network Management Protocol or SNMP to poll routers, read their interface counters and compute the amount of traffic going through their interfaces. They can use the computed data to build graphs depicting the evolution of

In the modern interconnected digital environment, businesses rely heavily on their networks to maintain smooth operations, efficient communication, and data exchange. As per TechTarget Report, Cybercriminals will be able to steal more than 33 billion records by 2023 (175% from 2018). However, the majority of cyberattacks happen via networks, making them a crucial resource for understanding threats to an organization and its systems. This is where Network Traffic Analysis (NTA) comes into play. Let’s dig more profoundly into the practice of overseeing network activities to gain valuable insights into potential threats and IT-related issues. What is Network Traffic Analysis? In the realm of network management, the capability to handle diverse forms of traffic is a fundamental aspect of design. However, it’s important to recognize that not all network activities carry the same weight. The ability to discern potential security vulnerabilities and pinpoint uncommon operations that might trigger problems, including network downtime, becomes pivotal. This is precisely where Network Traffic Analysis (NTA) assumes a crucial role. Network traffic analysis involves the methodical scrutiny of a network’s actions and accessibility. This approach includes the continuous monitoring of data movement across distinct sections of the network, encompassing details such as data content, timing, and locations.Why is network traffic analysis important?NTA revolves around safeguarding your data origins, guaranteeing peak network performance, and spotting potentially harmful traffic trends. Here are several reasons why organizations should adopt it. Automatic Network Anomaly Detection: Unlike traditional solutions that may miss changes caused by normal network behavior, network traffic analysis tools automatically identify anomalies without manual monitoring. Cybersecurity experts utilize these tools to swiftly detect and address threats, leveraging contextual information for efficient resolution. Security Insights: Once a threat is recognized, an NTA solution can extract distinct attributes, such as IP addresses, which serve as building blocks for indicators of compromise (IoCs). This data can help detect additional threats and preemptively thwart future attack attempts. Traffic Analysis: Network traffic analysis offers detailed traffic data for devices, offering valuable insights into the reasons behind sudden increases in traffic. By observing the frequency, volume, and timing of these spikes, you can discern whether they stem from increased productivity or potentially indicate a hacking attempt. Always-On Network Accessibility: For any organization, constant network availability is vital. Network traffic analysis offers insights into network uptime, improving performance. The swift component analysis identifies downtime sources, aiding security teams in threat detection and minimizing user

Monitoring tools help ensure that the network remains secure and compliant with industry standards, which is essential for avoiding legal penalties and protecting sensitive data.Real Life Example #5In 2019, Capital One suffered a data breach that affected over 100 million credit card customers and applicants. The breach exposed sensitive information, including Social Security numbers and bank account details. In response, Capital One strengthened its security posture and compliance efforts, particularly focusing on compliance with financial industry regulations like the Gramm-Leach-Bliley Act (GLBA).Capital One employed AWS CloudTrail and Splunk to monitor its cloud-based infrastructure continuously. These tools helped the company enhance its security and compliance by providing real-time visibility into user activity and ensuring that all data handling met industry standards.Through continuous monitoring and a strong focus on compliance, Capital One improved its overall security posture and minimized the risk of future breaches.

It involves using specialized network traffic analysis and network monitoring tools to gain insights into various aspects of the network’s operation, such as: The performance of network devicesThe efficiency of data traffic managementThe overall health of the network infrastructureHow to monitor network traffic?Embarking on network traffic monitoring involves selecting the optimal data source, identifying key network applications, and implementing network traffic monitoring solutions. Three primary data sources—flow data, packet data, and WiFi data—are crucial for gaining visibility into network traffic patterns, bandwidth usage, and wireless network analysis. Once a data source is chosen, mapping out the network landscape with a topology mapper helps understand network access and usage patterns. Finally, deploying a suite of network monitoring tools tailored to the network’s scale, complexity, and specific challenges is essential. These tools should align with budget constraints, integrate seamlessly with existing technology stacks, and prioritize holistic monitoring, enhanced performance, and bolstered security measures.What Tools are Best for Network Traffic Monitoring?Why is it important to monitor
