Summary/Abstract: Numerous companies in Serbia have come under attack, including large companies, state-owned companies and institutions. Various security vulnerabilities have been identified, which clearly indicates insufficient education of employees in the field of information systems security, as well as insufficiently developed awareness of the consequences of misuse of unprotected information and vulnerability of systems and applications. This paper lists some security measures, which may prevent unauthorized access to the system and misuse of personal or sensitive data. The paper also lists some examples of attacks using ransomware, which have led to massive data losses. These attacks were carried out via email, which is one of the most common types of malware attack and brings us to the question of whether it is necessary to introduce additional education on the topic of cyber security through the school system.
