Basic Digital Security for Everyone

Digital security is no longer just for specialists: data leaks, phishing attacks, and account takeovers affect everyone who uses the internet, online banking, or social networks. Without basic protection skills, you and your data become vulnerable to attackers who refine their deception methods every day. This course is designed so you can confidently navigate the digital environment, understand real risks, and make informed decisions without relying on luck or third-party services.

The program covers key aspects of digital hygiene. You will review in detail how to create and manage strong passwords using password managers and the principle of unique credentials for each service. You will study two-factor authentication (2FA) methods—via authenticator apps and hardware keys. A separate block focuses on protecting personal data: privacy settings on social networks, minimizing your digital footprint during registrations and purchases. You will learn how to recognize phishing emails, fake websites, and social engineering, as well as how to use public Wi-Fi networks safely using VPN and certificate checking. You will also cover principles of data encryption on devices and in messengers, backup practices, and software updates.

Special attention is given to practical scenarios and common mistakes. You will learn to distinguish safe actions from risky ones using concrete examples: how to respond to a suspicious email “from the bank,” whether to use one password for all accounts, and what personal information to publish publicly. Cases are also discussed where automatic updates can be dangerous, and how to verify the authenticity of apps before installing them. The course is structured so you can apply the acquired knowledge immediately in everyday work with devices and services.

The course is intended for adult users who want to protect themselves and their loved ones online: parents who supervise their family’s digital security; employees from non-IT departments who handle confidential data; teachers and librarians who teach others the basics of security; and retirees learning online services and worrying about scams.

By the end of the course, you will master basic digital security terminology, understand the principles behind major threats and protection methods. You will be able to independently assess the security of your passwords, configure two-factor authentication, identify phishing attempts, and make well-founded decisions about what information to trust and with whom on the internet. This knowledge will serve as a foundation for further in-depth study of the topic or for using digital technologies more confidently and securely.
