A security manager wants to reduce the number of steps required to identify and contain basic threats. Which of the following will help achieve this goal?

SOAR (Security Orchestration, Automation, and Response) platforms automate and orchestrate security tasks, including threat identification, containment, and response. By integrating various security tools and defining playbooks, SOAR reduces manual steps and accelerates the incident response process, directly addressing the goal of reducing steps to identify and contain basic threats. SIEM (Security Information and Event Management) aggregates and analyzes security logs but doesn't inherently automate response actions. DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol and not relevant to general threat containment. NIDS (Network Intrusion Detection System) detects intrusions but doesn't automate the containment process.
