SIEM and SOAR have a lot of components in common. How do they differ in the role they play in Cyber Security?
If you've been working in cybersecurity, you've likely come across SOAR and SIEM technologies. There are differences between their capabilities, although they have a fair amount of commonalities. They both collect data, but the quantity of data, type of data, and type of response is where they differ. As threats have advanced, security professionals may be in need of both.
That's where SOAR and SIEM come to the rescue, although there has been some confusion as to the difference between the two. The two technologies have different competencies, but can be combined to increase a security team's or SOC's effectiveness.
In short, SIEM aggregates and correlates data from multiple security systems to generate alerts while SOAR acts as the remediation and response engine to those alerts.
SIEM is the collection and aggregation of security data sourced from integrated platforms logging event-related data - firewalls, network appliances, intrusion detection and prevention systems, etc. - then correlates data across devices, categorizes, and analyzes incidents before issuing alerts. The alerts are identified by using sophisticated analytical techniques and machine learning, which require fine tuning. This leaves a lot of alerts for a security team or SOC to prioritize and remediate; a difficult, time-consuming process.
SOAR, on the other hand, is designed to help security teams automate the response process by gathering alerts, managing cases, and responding to the endless alerts generated by SIEM. With SOAR, security teams can integrate with security alerts and create adaptive, automated incident response workflows. This gives SecOps the ability to prioritize threats and deliver faster results.
