Learn the basics of ethical hacking and explore cybersecurity for systems and networks in this free online course.

This course breaks down the process of penetrating and testing systems to improve cybersecurity. We study the idea of ‘reconnaissance’, which requires the observation of systems to better understand their security features and anticipate potential threats. We lay out the technical protocols of ethical hacking, such as TCP/IP, ICMP, ARP and DNS. The course covers hacking using a Microsoft Windows operating system.

We then examine various attacks made on web technologies, including ‘denial of service’ and other web-based cyber attacks. We explain how to secure systems against such attacks, which is helpful for anyone working in cybersecurity for systems and networks.

The course then wraps up with penetration testing for wireless networks, also called ‘pentesting’. We show you how to secure various wireless networks against attacks, including types ‘A’, ‘B’, ‘G’ and ‘N’ used under the ‘802.11’ protocol. This course teaches you everything you need to know to become an ethical hacker. Sign up to learn about cybersecurity and how to employ your new skills for good.
