The article addresses education as the smartest investment in cybersecurity. One of the most intriguing findings is that 95% of security incidents involve human errors. Most security attacks are concerned with human weakness to attract victims and persuade them to give involuntary access to personal and sensitive information. To eliminate errors caused by social engineering and negligence and to increase users’ awareness of the threats, technologies and services should be combined with education. Education in the field of cybersecurity is a necessary consideration for both individuals and families, as well as for businesses, governments and educational institutions. For families and parents, the online safety of children is of major importance. Equally essential is the protection of information that might affect your personal finances, and precious family assets, such as photos, videos etc. For educational institutions, it is important to understand the link between the online world and the "real" one. Teachers, staff, students, tutors, pupils, etc. should be trained in appropriate on-line behavior to reduce vulnerabilities and create a safer online environment. A better awareness through security education can help enterprises protect their intellectual property and ensure availability of services. Governments hold an enormous amount of personal data and records of their citizens, as well as confidential government information, which most often serves as a target for attack. Only through education and awareness, the confidence in public services can be gained. Cybersecurity depends on education.
