How to Use Unicornscan (BSWR)

As a defender, you can use Unicornscan to evaluate your network and identify vulnerabilities. In this Unicornscan tutorial, Robert Smith shows you how to use this popular port scanning tool to determine what ports are being used for network communications so you can protect them. It’s another great Breaking Stuff with Robert (BSWR) session.

Course Description

Who Needs to Use Unicornscan?

Unicornscan is a popular port scanning tool that has hundreds of individual features. Port scanners are essential tools to have when you are beginning a security investigation on a local or remote network. The unicornscan port scanner, an attempt at a User-land Distributed TCP/IP stack, is designed to provide users with a better interface for initiating stimuli in and then measuring responses from TCP/IP enabled networks or devices.

Unicornscan is most often used by network and system administrators and programmers. This tool is essential for scanning servers and hosts to see what available ports are being utilized for network communications.

Why Use the Unicornscan Tool?

The Unicornscan port scanner can be used to gather and correlate network and OS information. It was built for security testing and research communities. The tool was designed according to the acronym SAFE – Scalable, Accurate, Flexible, and Efficient. Unicornscan is widely used because of its many scanning capabilities, as well as uncommon network discovery patterns, which provides unique alternative methods to explore details about remote operating systems and services.

Some of the main benefits of Unicornscan include:

  • Asynchronous stateless TCP scanning (including all variations of TCP flags)
  • Asynchronous protocol-specific UDP Scanning
  • Asynchronous stateless TCP banner grabbing
  • Passive and active remote operating system, component, and application identification using analyzed responses
  • PCAP file filtering and logging
  • Relational database output
  • Customizable data-set views
  • Custom module support
  • Because Unicornscan has its own TCP/IP stack, it enables users to scan much faster than other port scanners. This can make a big difference when scanning large networks for researchers and penetrations testers. Additionally, because there is a built-in TCP/IP stack, Unicornscan is able to send packets with different operating system fingerprints than the OS of your host. This allows users to obscure their identity.

    If you are a programmer, system administrator, network administrator, penetration tester, or other IT security professional who needs to learn Unicornscan for port scanning, this Unicornscan tutorial will be useful to take. The course will teach you the basics of Unicornscan and how to use it.

    This course is part of a Career Path:
    Become a Penetration Tester
    Last year, penetration testers ranked as one of the three most in-demand jobs in the growing cybersecurity job market. To become a penetration tester, a college degree is not necessary since it’s a skills-based profession. Employers want professionals who can demonstrate the required skills, regardless of education. Cybrary offers realistic, virtual lab environments where you will gain real-world, hands-on skills you will use as a penetration tester.
