The question describes the core functions of a Security Orchestration, Automation, and Response (SOAR) platform. SOAR systems are specifically designed to accelerate incident response by integrating with various security tools and data sources. They use "playbooks"—pre-defined, automated workflows—to execute standardized response actions without manual intervention. This automation of repetitive tasks and orchestration across different technologies allows security teams to handle alerts more efficiently and consistently, which directly aligns with the system described.

A. XDR: Extended Detection and Response (XDR) focuses on collecting and correlating data from multiple security layers (endpoint, network, cloud) to improve threat detection and investigation, not primarily on executing automated playbooks.

B. STEP: This is not a standard or recognized acronym within the cybersecurity industry for a technology that performs the functions described in the question.

D. SIEM: A Security Information and Event Management (SIEM) system's primary function is to aggregate, correlate, and analyze log data to generate security alerts, not to orchestrate and automate the response actions.

"What is Security Orchestration

Automation and Response (SOAR)?" Cortex Documentation. "SOAR allows organizations to collect data about security threats and respond to security events without human assistance. This is accomplished by... using playbooks

which are a series of actions that can be automatically executed." (paloaltonetworks.com/cyberpedia/what-is-soar)

"SIEM vs. SOAR vs. XDR: What’s the Difference?" Cortex Documentation. "A SOAR platform is a solution that helps security teams... respond to those alerts. It does this by automating and orchestrating workflows and tasks... A SIEM platform

on the other hand

is a solution that helps security teams detect and analyze those threats in the first place." (paloaltonetworks.com/cortex/siem-vs-soar-vs-xdr)
