You work as an Incident handling manager for a company. The public relations process of the company includes an event that responds to the e-mails…

Based on the standard incident handling lifecycle, such as the one defined in NIST SP 800-61, the phases following Identification are Containment, Eradication, and Recovery. In this scenario:

Containment (represented by the non-standard term 'Contamination') is the immediate step to limit the damage, such as by implementing temporary filters or blocking the source of the spam.

Eradication involves removing the root cause of the incident, which means fixing the vulnerability in the public relations e-mail process that allows spammers to exploit it.

Recovery is the final step in the resolution, where the corrected e-mail process is restored to full, secure operation and monitored to ensure the solution is effective.

A. Identification: This phase is largely complete, as the problem has already been discovered. The question asks for the subsequent phases involved in resolving the issue.

E. Preparation: This phase occurs before an incident is detected. It involves establishing the policies, procedures, and tools for incident handling, not responding to an active incident.
