Cyber security refers to the practice of protecting systems, networks, and programs from digital attacks. These cyber attacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users by way of its systems; or interrupting normal business processes. Implementing effective cyber security measures is crucial for individuals and organizations alike to safeguard their digital assets and maintain trust. It encompasses a range of technologies, processes, and controls designed to protect computers, networks, devices, and data from unauthorized access, damage, or theft. The primary goals of cyber security are to ensure the Confidentiality (preventing unauthorized disclosure of information), Integrity (ensuring information is accurate and complete), and Availability (ensuring systems and data are accessible when needed) of information and systems, often referred to as the 'CIA triad'.

Cybercrime is defined as any criminal activity that involves a computer, network, or device. It encompasses a wide range of illegal activities, from hacking and identity theft to online fraud and the distribution of malicious software. Cybercriminals exploit vulnerabilities in systems and networks to achieve their illicit goals, often causing significant financial and reputational damage to individuals and organizations. Examples include phishing, ransomware attacks, and online scams.

Cyber terrorism refers to the use of computer networks and digital technology to carry out acts of terrorism. This can involve disrupting critical infrastructure, spreading propaganda, inciting violence, or launching cyber attacks against government or private entities to cause fear, panic, or significant societal disruption. Unlike typical cybercrime, which is often motivated by financial gain, cyber terrorism is primarily driven by political or ideological objectives. The aim is to achieve strategic goals through the use of digital means, causing widespread fear and undermining national security.
