Hot data is necessary for live security monitoring.
Archive data (cold data) is not available fastly. It takes days to make archive data live if the archive data time frame is more than 30 days (in most of the SIEM solutions).
As an example, SolarWinds said the attackers first compromised its development environment on Sept. 4, 2019. So, to investigate the SolarWinds case, we have to go back to Sept. 4, 2019, from now on (July 13, 2021). In this case, we need at least 18 months of live data.
The second example of why hot data is critical is from the IBM data breach report. The average time to identify and contain a breach is 280 days, according to this report.
Hot data gives defenders the quick access they need for real-time threat hunting, but hot data is more expensive than the archive option in current SIEM solutions.
Keeping data hot for SIEM use is inevitably one of the most expensive data storage options.
What are your thoughts about it, dear professionals?(less)

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.
SIEM vs SOAR
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.
Are event correlation and aggregation both needed for effective event monitoring and SIEM?
