In today’s digital world, the amount of network traffic generated by organizations is growing at an exponential rate. As the amount of data flowing through a network continues to grow, it becomes increasingly difficult to monitor and analyze network traffic. This is where Network Traffic Analysis (NTA) comes in handy.

NTA is a powerful tool that enables organizations to identify and analyze traffic patterns on their networks. By monitoring network traffic, NTA can help organizations detect potential security threats, such as malware, phishing attacks, and data breaches. In this article, we will take a closer look at NTA and explore its key benefits.

How Does Network Traffic Analysis (NTA) Work?

NTA works by capturing and analyzing network traffic data in real time. This data is then used to identify patterns and anomalies that may indicate a security threat. NTA tools use a range of technologies, including machine learning and behavioral analysis, to detect abnormal network behavior.

One of the key benefits of NTA is that it provides organizations with a comprehensive view of their network activity. By analyzing network traffic data across devices and applications, NTA can help organizations identify potential security threats that may have gone unnoticed using traditional security tools.

Key Benefits of Network Traffic Analysis (NTA)

With the “it’s not if, it’s when” mentality regarding cyber attacks today, it can seem overwhelming for security professionals to ensure that as much of an organization’s environment is covered as possible.

It is essential to gain insight into your network data in order to stay protected from potential attacks. Having a better view of their attack surface can help them detect and stop threats earlier on.

Benefits of NTA include:

• Better visibility into devices connecting to your network (e.g. IoT devices, healthcare visitors)
• Meet compliance requirements
• Troubleshoot operational and security issues
• Respond to inquiries faster with rich details and additional network context

An important step in setting up an NTA is to ensure that you are collecting data from the right sources. Flow data is great if you’re looking for traffic volume and mapping the journey of a network packet from its origin to its destination. This type of data can facilitate the recognition of any unapproved WAN traffic and the utilization of network resources & performance. However, it may not have enough detail or context to investigate cybersecurity problems thoroughly.

Packet data extracted from network packets can help network administrators understand how users are implementing/operating applications, track usage over WAN links, and monitor suspected malware or other security incidents. 

What is the Purpose of Monitoring Network Traffic?

The purpose of monitoring network traffic is to identify potential security threats. By analyzing network traffic data, organizations can detect unusual patterns or anomalies that may indicate a security breach. This enables organizations to take proactive measures to protect their networks and data.

There are some Purposes for monitoring network traffic include:

• Detection of ransomware activity
• Monitoring data exfiltration/internet activity
• Track a user’s activity on the network, through User Forensics reporting
• Provide a list of what devices, servers, and services are running on the network
• Highlight and identify the root cause of bandwidth peaks on the network
• Provide real-time dashboards focusing on network and user activity

Why do you need an NTA Solution?

Huge advancements in technology have ensured that most companies and people are heavily dependent on the constant availability of online networks and data. Business dealings just got a lot easier with the world at our fingertips. Yet, the data we depend on is always vulnerable to cyber attacks – especially sensitive data that can cripple production and tarnish a company’s reputation.

Therefore, there are several reasons to invest in an elite network traffic analysis tool:

• Increased interest in corporate data
• Stronger Network Performance
• Advanced Public Security Stature
• Resource Efficiency
• Rapid Response

Conclusion

NTA is a powerful tool that enables organizations to monitor and analyze network traffic in real time. By detecting potential security threats, NTA can help organizations protect their networks and data against cyberattacks. When selecting an NTA solution, organizations should look for a solution that provides real-time monitoring, uses machine learning techniques, and provides comprehensive network visibility.
