According to the NIST, a computer incident is a violation or imminent threat of violation of computer security policies, acceptable use policies, or standard security policies.
Let's take a few examples of the incidents that have occured:
- A developer clones the latest source code from Git repository and shares it online to the public domain
- An employee is tricked into opening up file in a malicious mail stating performance appraisal, which has an attached excel sheet with a malicious executable attached to it
- An attacker is sending lot of GET requests to an application-specific API, which is known to slow down the servers, with the intention of creating a DoS-based attack
