Meaning of incident

Incident is a word used in English to mean an incident or event. The international standard ISO 22300 (2.1.15) defines an incident as “a situation that can lead to, or could lead to, interruption, disruption, loss, emergency, or crisis.”

In

the IT

field, incidents are often used in security-related and system operation situations, and the meaning changes in each case.

security incident

A security incident refers to any event that poses a security threat. Cyber attacks, which have become increasingly sophisticated in recent years, are also a typical security incident. For example, there are DoS (Denial of Service) attacks that target vulnerabilities in corporate websites and servers by sending fraudulent data or large amounts of data to disrupt system operation. Malicious and human-induced security incidents can cause malware infections and unauthorized access, leading to identity theft and information leaks and leaks.

Security incidents are not just external threats such as cyber attacks. Information leaks due to malicious intent by internal employees, unintentional or careless human errors, and misplacement, loss, or theft can also lead to security incidents.

System operational incidents

In the IT field, the state of the system may make it impossible for users to perform tasks that they would otherwise be able to perform normally. For example, it is common to see an error message that prevents you from logging in, or your password is locked.

Such unexpected conditions and events are also called incidents. The causes of system operation incidents include malfunctions of devices such as computers, user errors, and software failures and defects.

It is difficult to completely eliminate unexpected failures. However, in order for users to be able to quickly recover from an incident in which they are unable to perform tasks that normally would normally be possible, it is necessary to implement incident management by recording incidents and accumulating knowledge from the time they are resolved. It’s important to go.
