Question #: 81
Topic #: 5

[Introduction to Incident Handling and Response]

Alice is an incident handler and she has been informed by her lead that the data on affected systems must be backed up so that it can be retrieved if it is damaged during the incident response process. She was also told that the system backup can also be used for further investigation of the incident. In which of the following stages of the incident handling and response (IH&R) process does Alice need to do a complete backup of the infected system?

AContainment

BIncident recording

CIncident triage

DEradication

Show Suggested Answer

Suggested Answer: A

In the incident handling and response (IH&R) process, backing up the data on affected systems is a critical step that usually falls under the Containment phase. The Containment phase is crucial for limiting the scope and severity of an incident, ensuring that it does not spread further or affect additional systems. Backing up affected systems during containment is essential for several reasons: it preserves a snapshot of the system in its current state for forensic analysis, ensures that data is not lost if the system needs to be wiped or altered during the response process, and helps in the recovery process if data is corrupted or lost.

By performing a complete backup of the infected system during the Containment phase, Alice ensures that there is a reliable copy of all data and system states before any major actions, such as eradication or deeper forensic analysis, are taken. This step is also preparatory for the potential use of the backup in analyzing how the incident occurred and in restoring system functionality after the incident is resolved.

I thought backups were done during eradication?

I’m leaning towards containment too, but I wonder if incident triage could also involve securing data? It’s a bit confusing.

I practiced a similar question, and I feel like the eradication stage is more about removing threats, not backing up. So maybe it's not that one.

I'm not entirely sure, but I remember something about incident recording being important for documentation. Could it be that stage?

I think the backup should happen during the containment phase, right? It makes sense to secure the data before doing anything else.

This is a tricky one. I'm not entirely confident, but I think the backup would need to be done during the containment or eradication stage, since those are focused on preserving evidence and preventing further damage.

Okay, I've got a strategy for this. The question is asking about when the backup should be done, so I need to consider the different stages of the incident handling process and which one would require a full system backup.

Hmm, I'm a bit unsure about this one. The question mentions backing up data, but I'm not sure which stage that would fall under. I'll have to think this through carefully.

This seems like a straightforward question about the incident handling process. I think the key is to identify the stage where data backup is most critical.

I'm just gonna guess... D. Eradication. Backing up the system makes sense before you start removing the infection. Wouldn't want to lose any evidence, right?

Yes, that's correct. Backing up the data during the Containment stage is crucial for ensuring we have a copy of the affected system before taking any further actions.

Hold up, who named this person 'Alice'? Sounds like a children's book character, not a real incident handler. Anyway, I'd say D. Eradication is the way to go.

C. Incident triage. Alice needs to assess the situation first before doing anything drastic like a full system backup. Gotta triage that incident, yo!
