About this course

This course teaches cybersecurity fundamentals from zero to an advanced level. It is a comprehensive course that combines networking basics, protection basics and ethical hacking in one complete path. It starts with an introduction to the field of cybersecurity, its tracks and the map of the field, then moves on to networking basics, IP addressing and subnetting, Linux basics, commands and permissions, SQL basics and its uses, and an introduction to HTML and CSS. It then goes deeper into the history of cybersecurity, threats and breaches, the components of security known as the CIA triad, encryption and data hiding techniques, then the phases of ethical hacking, security policies, types of attacks and how to protect against them, wireless network security, data protection and privacy, safe browsing, smartphone security and enterprise security. The course suits complete beginners in this field and needs no previous experience, but it does require a special working environment, and the course explains how to set it up. It is both theoretical and practical, starting with concepts and then applying them with tools, Linux and networks. Afterwards, the learner will have built a solid foundation in cybersecurity, ready to enter the field with confidence and a deeper understanding of how to protect systems and information.

HTML ElementsExplains HTML elements such as external and email links, lists, setting width in percent rather than pixels to suit different screens, and building tables with borders.13:16
CSS and FormsExplains comments in HTML, linking a CSS file with the link tag inside head, meta tags, and form elements such as input fields and their types.19:59

Security Component

4 lectures

History and Evolution of CybersecurityCovers the history of information security, the difference between cybercrime and cyberwarfare, the idea of attackers targeting the weakest link, and the defensive principles of authentication, authorization and logging.25:48
Threats and BreachesPresents examples of threats and breaches: the scale of data leaks, a site for checking whether an email was leaked, the Stuxnet worm, the WannaCry ransomware, and the risks of exposing personal information on Facebook.29:30
Components of Security (CIA)Explains the CIA components of information security, confidentiality, integrity and availability, the idea of key-based encryption and file fingerprints, and encrypting drives and files in Windows with a backup of the digital certificate.22:15
Encryption and ProtectionExplains file and disk encryption in Windows using a digital certificate, why the certificate must be imported, how encryption protects data on a stolen device, and the difference between GPT and MBR.17:30
