CS0-003 Security Operations Practice Question
Which analysis technique involves examining the parent-child relationships of processes to identify potentially malicious activity?
⚠ Common exam trap
CS0-004 often tests the confusion between different analysis techniques, where candidates might choose memory analysis for process relationships because processes reside in memory, but the specific focus on parent-child relationships is unique to process analysis.

Correct answer & explanation
✓
Process analysis
Process analysis involves examining running processes, their attributes, and especially their parent-child relationships to detect anomalies such as a suspicious process spawned by an unexpected parent (e.g., a word processor spawning cmd.exe). This technique is fundamental in endpoint detection and response (EDR) and forensic investigations to identify malicious activity like process injection or lateral movement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Network analysis
Why it's wrong here
Network analysis involves inspecting packet captures, flow logs, and protocol behaviors to identify anomalies, lateral movement, or data exfiltration. While it is critical for detecting command-and-control communication, it does not provide visibility into local endpoint execution structures or the hierarchical relationships between parent and child processes.
- ✗
Memory analysis
Why it's wrong here
Memory analysis focuses on extracting volatile data from RAM to identify injected code, rootkits, and active network connections. Although it can reveal running processes at a specific point in time, it is not the primary technique used to map out the historical execution lineage and hierarchical parent-child process trees.
- ✗
Registry analysis
Why it's wrong here
Registry analysis inspects the Windows Registry database to find configuration changes, evidence of execution, and persistence mechanisms like Run keys. This technique is valuable for determining what is configured to run on boot, but it does not track active process execution hierarchies or parent-child relationships.
- ✓
Process analysis
Why this is correct
Process analysis specifically evaluates the execution lifecycle, metadata, and hierarchical relationships of running programs. By examining process trees, analysts can identify anomalous parent-child relationships, such as a web server spawning a command shell, which is a classic indicator of compromise.

Key term
EDR
Endpoint Detection and Response (EDR) is a cybersecurity technology that continuously monitors endpoint devices to detect, investigate, and respond to advanced threats.
Key term
Lateral movement
Lateral movement is the technique attackers use to move through a network from one compromised system to another, seeking sensitive data or higher privileges.
