Network Traffic Analysis (NTA) for Malware Detection

It is necessary for businesses to monitor their networks; Network Traffic Analysis, SOC Monitoring, and Malware Threat Detection. Cyber threats change each day, and traditional security tools commonly overlook concealed malware. That’s where Network Traffic Analysis (NTA) comes in. As a result of observing and examining network traffic, businesses can identify dangers before any damage is done.

Now that we know what NTA is, how it detects malware, and how to do continuous monitoring, let’s get into it.

What is Network Traffic Analysis?

NTA (Network Traffic Analysis) is the observation, collection, and analysis of data (traffic) passing through the networks in order to identify any suspicious behavior. Traffic, the sum of all activity going through a network, is created by every device connected to it, be it emails, file transfers, or browsing activity.

NTA tools observe this traffic, helping in the detection of irregularities, abnormal behaviors, and possible security threats before they turn into full-blown incidents. NTA is not a replacement for traditional antivirus software, which scans files on a host device, but rather a more powerful means of malware detection, looking at how data flows between hosts on a network.

How NTA Detects Malware

Malware often coils in encrypted traffic, masquerades as run-of-the-mill activity, or lateral hops around within a network, to evade notice. NTA works in a similar way, employing analytics and machine learning to uncover these hidden threats. Here’s how:

1. Identifying Abnormal Traffic Patterns

• Malware will typically create unusual peaks in data flows or contact unrecognized external servers.
• NTA tools can identify unexpected spikes in traffic, unusual connection attempts, or unauthorized remote access.

2. Detection of Command & Control (C2) Communications

• C2 servers are used by attackers to control compromised machines.
• NTA identifies outbound connections to known malicious IP addresses or domains indicative of compromise.

3. Spotting Lateral Movement

• Once on a system, malware propagating between devices and servers.
• NTA reveals surprising relationships that can suggest an active attack.

4. Monitoring Encrypted Traffic Without the Need for Decrypting

• A lot of malware planted by cybercriminals are hidden behind encrypted information.
• NTA works without decrypting data, identifying irregular patterns, unusual packet sizes, and behavior anomalies.

5. Detecting Data Exfiltration

By harvesting the info, but sending it out gradually to an unknown location so it is harder to detect.

Optimal Practices for Continuous Monitoring

Hence, network traffic analytics (NTA) should be used by businesses to continually monitor the activity of a network in order to extract the most return from SOC Monitoring and Malware Threat Detection. Here are some best practices:

1. Create a Normal Network Behavior Baseline

• Understand what normal traffic is so that you can track daily activity.
• It helps to detect deviations that may prove a security threat.

2. Implement an AI-Powered NTA Platform

• Modern NTA tooling leverages AI and ML for automated threat detection.
• AI even helps identify the most sophisticated threats in real-time.

3. Monitor for Insider Threats

• Security threats can also come from within; internal employees.
• Monitor for unauthorized access, abnormal file downloads, or a mass transfer of data.

4. NTA Add-on for Security Information and Event Management (SIEM)

• SIEM reviews the logs, and NTA reports on the traffic in real-time.
• They combine for a complete security solution.

5. Respond to Alerts Immediately

• Fast action is critical once NTA sees suspicious activity.
• Establish automated threat response mechanisms to reduce impact.

6. Maintain Security Policies on New Technologies

• Review access privileges and networking configuration frequently.
• Restrict access to authorized users and devices.
