The event that could cause harm to the information systems is known as a "threat." A threat is any potential danger or negative impact on the confidentiality, integrity, or availability of information systems. It can be caused by a variety of factors, including intentional or unintentional acts, natural disasters, or other environmental factors.
A threat is different from a risk, which is the likelihood or probability that a threat will exploit a vulnerability and cause harm. A vulnerability is a weakness in a system that could be exploited by a threat, while a weakness is a flaw or limitation that reduces the system's overall security posture.
Therefore, a threat is an event or action that has the potential to cause harm to the information systems, while a vulnerability is a weakness in the system that can be exploited by the threat. Identifying and addressing threats and vulnerabilities are essential parts of maintaining the security of information systems.
