Incident Typing

You should recall from this course that a useful way of characterizing incidents is by incident typing.

Incidents are categorized into 5 types based on complexity. Type 5 incidents are the least complex and Type 1 incidents are the most complex.

Factors that impact the determination of incident type include size of the ICS structure, number of resources employed, and the length of time the incident response is anticipated to last.
