Incident management is a crucial process in the field of information security, and it involves a series of steps to effectively respond to security incidents. The correct flow for incident management can be illustrated as follows:
A. Identify, log, categorize, prioritize, initial diagnosis, escalate, investigate and diagnose, resolve and recover, close
Identify: The first step is to identify the incident, which can be done through various means such as monitoring tools, alerts, reports, user complaints, etc.
Log: Once the incident is identified, it needs to be logged in a tracking system, which includes basic information such as the time, date, location, severity, etc.
Categorize: After logging, the incident needs to be categorized based on its type, nature, and impact. This helps in prioritizing the incident and assigning it to the appropriate team or individual for further action.
Prioritize: The next step is to prioritize the incident based on its severity, impact, and urgency. This helps in allocating resources and defining response times for the incident.
Initial diagnosis: Once the incident is categorized and prioritized, an initial diagnosis is performed to determine the scope and nature of the incident. This involves gathering more information and analyzing the incident to identify the root cause.
Escalate: If the incident requires additional resources or expertise, it needs to be escalated to the appropriate team or individual for further action. This can be done based on the severity, impact, or urgency of the incident.
Investigate and diagnose: Once the incident is escalated, a detailed investigation is performed to identify the cause, extent, and impact of the incident. This involves analyzing the system logs, network traffic, and other relevant data to determine the root cause.
Resolve and recover: Based on the investigation and diagnosis, appropriate measures are taken to resolve the incident and restore the system to its normal state. This includes patching vulnerabilities, removing malware, restoring data, and other necessary actions.
Close: Finally, the incident is closed once it is resolved, and all necessary documentation is updated in the tracking system.
Therefore, option A (Identify, log, categorize, prioritize, initial diagnosis, escalate, investigate and diagnose, resolve and recover, close) illustrates the correct flow for incident management.
