Open Source to Monitor Malicious Traffic And Discover Threats

Introduction

Companies are spending thousand of dollars to detect Malicious Traffic in the Network and discover threats. Today we will talk about open source Maltrail, which is a malicious traffic detection system. This tool helps the Network Administrator to monitor traffic and discover the threats in the Network or on the Server.

Maltrail can be deployed in inline or transparent mode. For deploying it in transparent mode, port mirroring is required to be done in the network to detect the malicious traffic as Intrusion Detection System. Using this tool we can protect our network from cyber attacks.

Maltrail tool login page
  • Successfully we got the login page.
  • For logging into this web interface, default credentials are:
    • Username: admin
    • Password: changeme!
  • After logging in, we started attacking the server by using the Nmap tool on another machine by using this command nmap -n –script-vuln 192.168.0.24
  •  Nmap will start’s scanning the target IP. Maltrail tool sensor will detect the attack on the server and show it in the tool’s web interface page.

  • Here, it shows the attack details number of threads, Events, security, sources, and trails details in the interface page.
  • This also generates the log files in /var/log/maltrail at this location.

Conclusion

We saw on how easily Maltrail tool detected the malicious traffic on server, using this tool we can secure our network from the attackers.
