Cyber security is important because of its potential effect on personnel, the ship, environment, company, and cargo. Cyber security is concerned with the protection of IT, OT, information and data from unauthorised access, manipulation, and disruption.

Technology and cyber systems have become essential to modern society being a component of many activities that have become dependent on information technology. Along with the benefit of the cyber technologies, insecurities arise, affecting all systems and infrastructures. The cyber threat and cyber-attack have a transnational component and effect, as worldwide systems are interconnected. Furthermore, the complexity of the action has implications for various actors at national, regional and international level.

The mistakes we make in personal accounts and profiles can have a direct impact on our closest contacts. A few months ago, around Christmas, many users were victims of a cyber attack through WhatsApp. Cybercriminals stole WhatsApp accounts through a method in which they gained the victim's trust by usurping the identity of one of the victim's contacts. One of the biggest problems with this specific phishing is that practically everyone uses this instant messaging system to communicate on a daily basis, so the theft of an account can lead to the infection or attack of many other Internet users.

The FBI has recently announced the increase in deepfake profiles detected in the selection processes of some companies. Imposters use stolen videos, images, recordings, and identities, posing as someone else to get a remote IT job. Hiring a deepfake can lead to serious problems when that fake employee gains access to sensitive corporate information and customer data. Doing so can pose a threat to a company's data security, and the organization may not have the opportunity to bring the scammer to justice.
