To stay undetected, cybercriminals continuously change their strategies. It is challenging for organizations to recognize important security concerns because they frequently use trusted tools that have already been deployed in a network environment and authentic credentials. Network traffic analysis tools were created to counter the ongoing innovation in cybercrime, and they assist in doing this by providing businesses with a practical means of foiling the schemes of even the most inventive hackers.
A major problem for corporations now is obtaining constant and complete visibility of their expanding networks. Fortunately, network traffic analyzers can be trusted sources of knowledge and insight, assisting organizations in understanding what is on their networks. This is because networks offer an impartial viewpoint that is frequently difficult to find in other data sources.
Why is NTA Important for Network Security?
Network traffic analysis is essential for monitoring network availability and activity in order to detect anomalies, optimize performance, and prevent attacks. Because assailants frequently employ trusted technologies already implemented in a network environment and swiftly alter their methods to evade detection, it is difficult for organizations to proactively identify severe network security issues.
In response to the constant ingenuity of assailants, network traffic monitoring technologies have emerged, providing organizations with a practical means of thwarting inventive attackers.
Moreover, the increasing adoption of cloud computing, DevOps practices, and the Internet of Things has made maintaining network visibility a difficult and time-consuming task.
Because they can ascertain what is genuinely on the network, NTA products can serve as a single source of truth for an organization. Networks observe everything and provide objective facts that other data sources often have difficulty obtaining. Consequently, there are numerous reasons to invest in superior network traffic analysis tools:

What are the Challenges of Network Traffic Analysis?
The difficulties and restrictions Network Traffic Analysis (NTA) encounters have an impact on its productivity and efficacy. Below, we'll go over some of the key points that NTA practitioners should keep in mind while using this approach to ensure the security of infrastructure:
- Data complexity and volume: Dealing with the vast and intricate amount of data that needs to be gathered and processed is one of NTA's main challenges. Terabytes or even petabytes of storage and computational power may be needed for NTA, depending on the network's size and architecture. Additionally, the data may have different formats, protocols, and levels of encryption and may come from many sources, including routers, switches, firewalls, or terminals. This makes it challenging to accurately and quickly correlate and interpret the data.
- Compliance and data privacy: Keeping the data that is collected and processed private and compliant is another difficulty for NTA. NTA may entail sensitive or personal information, such as IP addresses, user identities, or email messages, depending on the nature and content of the data. This might give rise to ethical and legal questions, particularly if the data spans organizational or national lines. In order to protect the data from unauthorized access or misuse, NTA practitioners must adhere to the pertinent laws and policies, such as the General Data Protection Regulation (GDPR) or the Health Insurance Portability and Accountability Act (HIPAA), and put in place the necessary safeguards, like anonymization, encryption, or consent.
- Validity and quality of data: Assuring the legitimacy and quality of the data that is gathered and evaluated is a third difficulty faced by NTA. Due to numerous causes, including network congestion, packet loss, or configuration mistakes, the data may be insufficient, erroneous, or out-of-date. In addition, hostile actors, like hackers or insiders, may modify or spoof the data in order to avoid detection or raise false alarms. In order to filter out the noise and unimportant data, NTA practitioners must verify and validate the data using methods like checksums, signatures, or timestamps, as well as sampling, aggregation, or compression.
- Analysis and interpretation of data: Making sense of and acting on the data after analysis and interpretation is NTA's ultimate difficulty. Particularly if it involves numerous layers, protocols, or devices, the data may be too complicated or ambiguous to comprehend. Additionally, the data can simply show the symptoms or effects of the abnormality rather than its underlying cause or influence. In order to recognize and categorize the anomalies, NTA practitioners must employ cutting-edge techniques like machine learning, artificial intelligence, or behavioral analysis. They must then use visualization, reporting, or alerting technologies to share their results and prompt action.
What are the Different Types of Network Traffic Analysis and How to Select NTA Tool?
There are various types of network traffic monitoring tools. Deep packet inspection (DPI) tools and flow-based tools are the two main categories that they fall under. You can choose from alternatives for software agents, archiving past data, and intrusion detection systems in these tools. Take into account the following five factors when determining which NTA solution is best for your business:
- Availability of flow-enabled devices: Does your network have flow-enabled devices that can produce the flows needed by an NTA solution that only takes flows, such as Cisco Netflow? DPI tools are vendor independent and accept raw traffic, which may be found on every network via any controlled switch. All that is needed for network switches and routers is traffic from a SPAN or port mirror on any managed switch.
- Data source: Not all NTA tools gather both flow and packet data since they originate from various sources. Make sure to examine your network traffic and identify the essential components, after which you should compare tool capabilities to make sure everything you require is covered.
- Network's nodes' points: Take into account whether the tool utilizes agent-based or agent-free software. Additionally, exercise caution while monitoring too many data sources at first. Instead, choose places where data converges with care, such as internet gateways or VLANs connected to crucial servers.
- Data in real-time against data in the past: Analysis of past occurrences requires historical data; however, certain techniques for observing network traffic lose that data over time. Additionally, see if the tool's cost is determined by the volume of data you intend to store. To identify the solution that best suits your demands and budget, have a clear grasp of the data that matters to you the most.
- Full packet capture, expense, and complexity: Some DPI technologies record and keep every packet, requiring expensive appliances, more money spent on storage and a lot of training and experience to use. Others perform more of the "heavy lifting", capturing complete packets but simply removing the pertinent information and metadata for each protocol. Although there is a significant reduction in data as a result of metadata extraction, the material is still accessible and useful, making it perfect for network and security teams.
How Do You Perform Network Traffic Analysis?
It can be difficult to analyze the traffic on your network. It involves collecting, archiving, and tracking every piece of data traversing your on-premises, hybrid, or multi-cloud infrastructure. There is no strategy that is universally effective across all networks and setups. It's more crucial to learn how to analyze network traffic in the first place than to talk about what to search for in an analysis tool. From there, you can select a tool based on the characteristics of your network.
Let's break down the network traffic analysis steps you need to take so you can feel better about the situation:
-
Determine Your Data Sources: Finding out what's available on your network is the first step. If you don't know something is there, you can't examine it or keep an eye on it. This stage consists of two components.
- Find all about Data Source Types: You must recognize and classify the many sources from which you can gather data. Applications, PCs, servers, routers, switches, firewalls, and other devices are available. Each of them can offer different metrics that you can gather and analyze.
- Choose your identification techniques: Appropriate techniques to use need to be decided later because you must define your data sources. Both human and automatic methods are acceptable. They quickly become out of date when searching topology maps and other documents, but that's part of the manual technique. This is why you take into account the automated processes of application and network discovery. Using SNMP, Windows Management Instrumentation (WMI), flow-based protocols, and transaction tracing are a few common auto-discovery techniques. You may discover application and network dependencies and increase infrastructure visibility by taking this action now.
-
Select the Most Effective Method for Gathering Data from Sources: The next step is to determine the most effective method for gathering the data you require from your data sources. The two main methods for gathering network traffic information are with and without agents.
- Using Agents to Collect: In order to collect data via an agent, you must install software on your data sources. Agents can gather data regarding active software activities, the efficiency of system resources, and inbound/outbound network traffic. Agent-based data collection can produce extremely detailed data, but it can also cause processing and storage problems.
- Collection without Agents: Utilizing protocols, processes, or APIs that your data sources already support is a requirement for data collection without agents. Methods like SNMP on network devices and WMI on Windows servers fall under the category of agentless collection. Flow-based protocols and firewalls with Syslog enabled both to aid in the identification of security events and traffic flows, respectively. Although agentless collection doesn't always yield data that is as detailed as agent collection, it nevertheless provides you with the user and system information you need to effectively evaluate network traffic.
-
Ascertain Any Collection Restrictions: It's tempting to jump right in once you are familiar with your data sources and the most effective technique to gather network traffic statistics from them. However, your company probably has guidelines and limitations about what and how infrastructure is maintained. Your ability to evaluate network traffic will suffer if you do not predetermine any of these needs.
Therefore, be sure to ascertain whether any ports need to be opened, say, for data collection. Additionally, make sure to ascertain whether departmental approval is necessary before data collection can start. Gathering information from various areas of the network can assist you in destroying silos.
Additionally, consider the sector that your company operates in. In highly regulated sectors like healthcare or finance, you might not be able to gather some types of data or you might need to store the data for a longer time. For network traffic analysis, more historical data can be useful, but it takes up storage. So be mindful of any regulations limiting or directing the collection of data.
-
Begin a Limited and Wide-Ranging Data Collection: The following action is to make your data sources collectible. Starting small and using a variety of data sources is crucial in this situation, especially if you manage a large network. This will make it easier to spot any system problems before you extend your network's reach. Gathering data from each Windows server should be the last thing you want to do; for example, discover that a certain cluster of servers is crashing all the time. As a result, start small with a diverse group and then grow from where you are.
-
Select the Location for Data Collection: All of the data you are gathering needs a destination. It is possible to store network traffic using specialized hardware or virtual appliances. Another choice is to install monitoring software on your actual or virtual devices.
Take your network's size and complexity into account. Virtual appliances might be more appropriate, for instance, if significant portions contain virtual devices. A hardware device can be a preferable choice if your company still primarily relies on on-premises physical infrastructure. A busy virtual network inside that network should not be monitored by a virtual appliance.
How you can evaluate network traffic depends on the target appliance. For example, it is more difficult to analyze data on a device that does not support viewing through a web UI. If you have a software component, your life will be easier. It will make it easier for you to collect and evaluate Data.
-
Turn on Ongoing Monitoring: Network traffic analysis is typically a continuous process. Sometimes you have to investigate a specific issue, such as an unexpected security breach or a sudden link failure. You might be required to assist in the analysis of network traffic from a portion of the network that, despite all the aforementioned efforts, is inaccessible or has monitoring restrictions. In these situations, you might need to gather and examine traffic once or for a set amount of time.
However, you must regularly monitor and gather data from your infrastructure in order to adequately analyze network traffic. Real-time and historical traffic collection require constant monitoring. Therefore, whichever solution you choose in the previous stage to serve as the network traffic destination must have continuous monitoring enabled.
-
Browse and Filter the Gathered Data: It requires sorting through gigabytes or more of data to analyze network traffic. All you have to do is observe, research, and interpret. You might be a terminal whiz who can grep your way through it to locate what you need, and you might believe that text files kept on your server or that appliance are okay. The ability to group network data into categories like application, byte size, protocol, IP subnet, etc. is necessary for traffic analysis. Using the command line to accomplish it is difficult.
In order to view all the collected data, you must make sure that you have a monitoring system in place. The time it takes to diagnose an application issue can be significantly decreased by being able to visualize network traffic via dashboards and reports. You can use this to find out who the most popular talkers are on your network and what they're going through. You can use it to locate the most popular programs and any problems they may be experiencing. This process might also help you identify low-bandwidth network connections that you can get rid of to reduce your expenses.
-
Configure Alerts: Making sure you are informed when there is a problem is the final stage. You cannot spend the entire day staring at dashboards and reports on your computer. Therefore, you must set up your monitoring system to provide you with an alarm when something goes wrong. Email is frequently used to send alerts, but you can also use connectors provided by monitoring solutions like Netreo to send alerts to yourself and your team. To prevent alert fatigue, any monitoring technology you employ must provide the appropriate notifications.
Don't forget to establish your own thresholds, too. You should be able to spot anomalies with the correct monitoring technology, but you are the expert on your network. You should set alert levels for your firewalls if you are aware that some ports are not permitted across them. Even if the instrument is brand-new, it can still help you spot problems and lead to further investigation.
