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?

Security Information and Event Management (SIEM) systems aggregate and analyze security data from various sources to identify threats. While effective for monitoring and reporting, SIEMs typically require manual intervention for threat evaluation and response. Thus, they do not inherently reduce the number of steps necessary for containment compared to SOAR solutions.

Domain-based Message Authentication, Reporting & Conformance (DMARC) is an email authentication protocol designed to protect against email spoofing. Although DMARC can enhance security by verifying email legitimacy, it does not facilitate the streamlined identification and containment of broader security threats, making it less relevant to the overall goal.

Network Intrusion Detection Systems (NIDS) monitor network traffic for signs of malicious activity. While they provide essential detection capabilities, NIDS lack the automation and orchestration features necessary to reduce the steps in responding to identified threats, which is where SOAR excels.
