Cyber-space refers to the boundless space known as the internet. Cyber-security is the body of rules put in place for the protection of the cyber space. Cyber-crime refers to the series of organized crime attacking both cyber space and cyber security. The Internet is one of the fastest-growing areas of technical infrastructure development. Over the past decades, the growth of the internet and its use afforded everyone this opportunity. Google, Wikipedia and Bing to mention a few, give detailed answers to millions of questions every day. Cyberspace is a world that contains just about anything one is searching for. With the advent of these advancements in information accessibility and the advantages and applications of the internet comes an exponentially growing disadvantage-Cyber Crime. Cyber security has risen to become a national concern as threats concerning it now need to be taken more seriously. This paper attempts to provide an overview of Cybercrime and Cyber-security. It defines the concept of cybercrime, identify reasons for cyber-crime and its eradication. It look at those involved and the reasons for their involvement. Methods of stepping up cyber security and the recommendations that would help in checking the increasing rate of cyber-crimes were highlighted. The paper also attempts to name some challenges of cybercrime and present practical and logical solutions to these threats.

Information Security is a crucial asset within an organization, and it needs to be protected, Information System (IS) Security is still threats a significant concern for many organizations. Is profoundly crucial for any organization to preserve Information System (IS) Security and computer resources, hardware, software, and networks, etc.The Information System (IS)assets against malicious attacks such as unauthorized access and improper use. This research, we developed a theoretical model for the adoption process of IS Security innovations in organizations, are numerous measures available that provides protection for organization IS assets, including (hardware, software, networks, etc.) and antivirus, firewall, filters, Intrusion Detection System (IDS), encryption tools, authorization mechanisms, authentication systems, and proxy devices. The model is to derive by the four combining theoretical models of innovation adoption, namely, the Theory of Planned Behaviour (TPB, Diffusion of Innovation theory (DOI), the Technology Acceptance Model (TAM),) and the Technology-Organisation-Environment (TOE) framework. The Computer security education needs to consider as a means of to combat against threats Arachchilage and Arachchilage et al., 2016). (Arachchilage and Love, 2013; While the process of innovation assimilation is as a result of the user acceptance of innovation within the organization. This model depicts security innovation adoption in organizations, as a two decision proceeding for any organization. The stage until its acquisition of innovation and adoption process from the initiation is considered as a decision made any organization. The The model also introduces several factors that influence the different stages of information Security and the innovation adoption process Adoption of IS security measures by the individuals and organizations.
