Abstract
CCybersecurity primarily deals with a clear interpretation of various issues related to attacks that occur on digital resources and subsequent remedies therein. While discussing the safety against attacks or crimes against digital resources, the confidentiality, integrity, and availability of such information must be preserved. The COVID-19 pandemic showed us that most human activities such as education, work in various fields, shopping, and communication shifted to online quickly. Therefore, the cybersecurity of computers, networks, and communication systems is critical. Cybersecurity is a challenging and rapidly evolving domain, and it is essential to stay up to date and use the latest protection technologies. This chapter introduces the basic cybersecurity concepts and terminology. The domains and the threats and actors are characterized extensively. Also, this chapter tries to explain the need for cybersecurity in the context of digitalization and increasing Internet usage. A short book outline is also presented.
