Need of SIEM when You have SOAR
1 like744 views
The document discusses the roles of SIEM (Security Information and Event Management) and SOAR (Security Orchestration, Automation, and Response) in cybersecurity. While SIEM is essential for log management and identifying security incidents, SOAR enhances incident response through automation and integrated data from various security tools. The convergence of SIEM and SOAR solutions is seen as beneficial, as together they improve operational efficiency and threat investigation capabilities.
Need of SIEM when You have SOAR
- 1. Security Orchestration, Automation & Response Need of SIEM when You have SOAR
- 2. Introduction (SIEM) A SIEM (Security Information and Event Management) makes sense of all event-related data of network appliances and intrusion detection systems by collecting and aggregating and then identifying, categorizing and analyzing incidents and events. This is often done using machine learning, specialized analytics software and dedicated sensors.
- 3. Introduction (SOAR) SOAR (Security Orchestration, Automation & Response) is designed to help security teams manage and respond to endless alarms at machine speeds. SOAR takes things a step further by accumulating comprehensive data gathering, case management, standardization, workflow and analytics to provide organizations the ability to implement sophisticated defense-in-depth capabilities.
- 4. “If I implement a SOAR solution, do I really need a SIEM?”
- 5. Do I Need SIEM If Have SOAR It’s a fair question and one that is compounded by the convergence we see happening across many categories within cybersecurity. Security operations teams have a broad spectrum of choices from pure-play security orchestration and automation platforms to traditional SIEMs that are adding orchestration capabilities.
- 6. SIEM & SOAR Solutions Together Security teams need log repository and analysis capabilities - that isn’t going away and is not what SOAR platforms are built to do. For many enterprise SOCs, this is just one of many vital functions their SIEM serves. Logging aside - we still see plenty of runway for SIEMs and SOAR solutions to work together symbiotically instead of serving as alternatives to one another for three key reasons.
- 7. Process and Playbooks SIEMs are largely focused on processing vs. process. By that we mean, SIEMs do a great job of addressing the technical challenges associated with ingesting and correlating millions of logs to surface up the ones the security team should be alerted on. One of the major ways SOAR solutions do this is through the ability to document and codify processes into repeatable playbooks.
- 8. SIEM vs SOAR
- 9. Function of SIEMs SIEMs serve a hugely important function by sounding the alarm when there appears to be malicious activity. But even the most skilled security analyst will need to use a variety of interfaces beyond their SIEM - EDR, threat intelligence, vulnerability management, user information and more - to put together the full story around a threat.
- 10. Function of SOAR SOAR solutions remedy this by allowing security teams to automatically gather the context they need to investigate an alert (or better yet, a group of alerts) from across their security ecosystem. This arms your team with a threat storyline that can be used to conduct deeper investigation, speed up analysis and make more definitive remediation decisions.
- 11. Security Operation Management While many SIEMs deliver a wide range of capabilities beyond what we traditionally expect - UEBA and automation, to name two - they haven’t been built with the intent of unifying people, process and technology within the SOC. By enabling the integration and security orchestration of an ecosystem of security tools, SOAR platforms are able to deliver the birds’ eye view teams need for day-to-day SOC operations.
- 12. Conclusion Is it possible that some highly forward-thinking SOCs can be successful using SOAR without a SIEM? Maybe so. But at least for now, most enterprise security operations teams will find the marriage of SIEM and SOAR to be the right formula for success. Both SIEM and SOAR intend to make the lives of the entire security team, from analyst to CISO, better through increased efficiency and efficacy.
