A cyber incident is any unauthorized or disruptive event that has an adverse effect on a computer network, system or data. It encompasses a broad range of incidents, such as cyber attacks, data breaches, network intrusions, malware infections, unauthorized access, system disruptions, or any other malicious or accidental events that compromise the confidentiality, integrity, or availability of digital information.
Cyber incidents can vary in severity and impact, ranging from minor disruptions to significant breaches that lead to extensive data loss, financial loss, reputational damage, or operational disruption.
