Figure 5.1 shows the simple incident response process advocated by NIST.

Notice that this process is not a simple progression of steps from start to finish. Instead, it includes loops that allow responders to return to prior phases as needed during the response. These loops reflect the reality of responses to actual cybersecurity incidents. Only in the simplest of incidents would an organization detect an incident, analyze data, conduct a recovery, and close out the incident in a straightforward sequence...
