NIST defines computer security incident as "a violation or imminent threat of violation of computer security policies, acceptable use policies, or standard security practices. Examples of incidents are:
  • An attacker commands a botnet to send high volumes of connection requests to a web server, causing it to crash.
  • Users are tricked into opening a “quarterly report” sent via email that is actually malware; running the tool has infected their computers and established connections with an external host.
  • An attacker obtains sensitive data and threatens that the details will be released publicly if the organization does not pay a designated sum of money.
  • A user provides or exposes sensitive information to others through peer-to-peer file sharing services."
