What does “forensics” refer to in a Security Operations process?

In a Security Operations (SecOps) context, "forensics" refers to digital forensics, which is the scientific process of identifying, collecting, preserving, and analyzing digital evidence or raw data. This data is gathered from sources like endpoints, memory, and network traffic. The primary goal is to conduct a detailed investigation to reconstruct events, determine the root cause, understand the scope of a security incident, and attribute the activity to a threat actor. This collection of raw data is the foundational step for any deep analysis.

B. Validating cyber analysts’ backgrounds before hiring is a personnel security or Human Resources function, not a technical process within an incident investigation.
C. Reviewing information about a broad range of activities is too generic; this better describes general security monitoring, not the specific, in-depth investigation that defines forensics.
D. Analyzing new IDS/IPS platforms for an enterprise is a security engineering or technology evaluation task, not a component of an incident response investigation.

1. National Institute of Standards and Technology (NIST) Special Publication 800-86

Guide to Integrating Forensic Techniques into Incident Response. Section 2.2

"The Forensic Process

" outlines the four main phases. The first phase

"Collection

" is described as acquiring data from various sources to serve as evidence for the investigation. This directly supports the definition in option A.

2. Palo Alto Networks

Cortex XDR™ Administrator’s Guide. In the chapter on "Action Center

" the "Forensic Data Collection" feature is described. It states

"To help you investigate a security event

you can use Cortex XDR to collect a forensics data file... from a specific endpoint." This shows the direct link between forensics and the collection of data for analysis in a Palo Alto Networks product.

3. Carnegie Mellon University

Software Engineering Institute (SEI)

Digital-Forensics-and-Incident-Response-Curriculum. Module 1

"Introduction to DFIR

" defines digital forensics as the process of "collecting and analyzing data" to determine what happened on a system and who was responsible. This academic source reinforces that data collection is a core component of the forensic process.
