Question 1
The main phases of incident management are:
Incident management is a structured operational process used to ensure security issues are handled consistently, evidence is preserved, impact is reduced, and improvements are implemented to prevent recurrence. The phases listed in option B match how incident management is commonly documented in operational security programs.
Reporting is the entry point: users, monitoring tools, and service desks raise alerts or tickets, capturing what happened, when, and initial impact. Clear reporting channels and defined severity criteria ensure incidents are escalated quickly and handled by the right teams. Investigation follows, focusing on fact-finding and evidence collection such as logs, endpoint telemetry, network traces, and user statements. Assessment determines scope, business impact, affected assets and data, and the likelihood of continuing compromise. This step drives prioritization and selects the appropriate handling path.
Corrective actions implement containment, eradication, and recovery activities, such as isolating hosts, disabling compromised accounts, applying patches, rotating credentials, restoring from backups, and validating system integrity. Corrective actions also include communications, documentation, and coordination with legal, privacy, and business stakeholders when required. Finally, review is the lessons-learned phase that updates playbooks, improves detections, closes control gaps, and ensures root causes are addressed through durable fixes rather than temporary workarounds.
The other options do not represent standard incident management phases: A is a marketing model, while C and D are incomplete or mis-ordered compared to established incident management lifecycle documentation.
