That’s where security orchestration, automation and response (SOAR) solutions excel. However, it’s also critical to recognize that SIEM isn’t a response tool. SIEM should provide the data and evidence needed to remediate threats to an incident response system. But SIEM is about detection, with tools that typically process between 10,000 and 500,000 events per second. Most cyberattacks focus on critical enterprise data - and once attackers gain access, your organization needs a rapid and efficient incident response process to empower analysts to stop them. Automation Enables Value-Added Activities Keeping up with changes and closing gaps remains critical, but AI can assess priorities and automate a large chunk of the workload. In addition, AI can help analysts implement, configure and support use cases within a SIEM system. Despite incomplete data and knowledge, cognitive capabilities can serve to automate and improve decision-making. ![]() But when SOCs lack the workforce to investigate these signals, AI can accelerate analysis and insight speed, identifying threats faster and more consistently than attackers can react. ![]() Instead, AI-powered analytics can be used to investigate and seek the root cause and chain of events that led to existing anomalies.ĪI won’t replace rules-based or machine-learning algorithms to detect potential threat signals. What analysts don’t need are solutions that generate even more alerts and lack integration with other security tools. ![]() As this need has grown, so have technologies such as machine learning and advanced historical analysis, which can surface anomalous behaviors and help defenders respond earlier to stop attackers and mitigate damages. But defenders need to identify symptoms of threat behavior as well as the threats themselves. SIEM solutions today tackle many security use cases, from detecting endpoint threats, to insider threats, to phishing attacks. Deploying a solution to improve detection, investigation and resolution requires vendors willing to share their expertise on an ongoing basis, so security teams aren’t forced to become experts themselves. The escalating number of data sources requires considerable effort to integrate and tune. Through it all, enterprises must still prove the efficiency and accuracy of their SIEM systems to compliance and regulatory auditors.ĭue to the cybersecurity skills shortage, organizations also need SIEM solutions that are simpler to deploy, manage and maintain. To detect and investigate threats, enterprises need a comprehensive view into on-premises and cloud - including hybrid cloud and multicloud - assets and network and user behaviors, helping analysts spot anomalies that could signal a breach or cyberattack. But as enterprises adopt new types of technology, such as the internet of things (IoT), the attack surface keeps growing, creating new blind spots. A Single Pane Captures a 360-Degree ViewĬomplex SIEM systems empower SOCs to detect both known and unknown threats and respond to incidents quickly and effectively. From compliance, SIEM expanded into threat detection and remains at the core of the security operations center (SOC). But the evolving threat landscape and sophistication of cyberattackers forced the answer to the question, “What is SIEM?” to change. Taking a step back to define the phrase, what is SIEM? SIEM is a combination of security information management (SIM) and security event management (SEM) that helps organizations detect threats via fine-grained, real-time visibility into on-premises and cloud-based activity.Īt one time, audit and compliance needs - from the Payment Card Industry Data Security Standard (PCI DSS) to Sarbanes-Oxley (SOX) to the Health Insurance Portability and Accountability Act (HIPAA) - drove the SIEM market. Defenders need a SIEM solution to detect threats in the extended environment, artificial intelligence (AI) to identify connections behind suspicious activity, and automated processes to rapidly shut down attacks. Security talent remains in short supply, while point solutions have become all too common. That’s unfortunate, because the threat environment isn’t standing still, both in terms of attack types and volume. But too many enterprises still don’t know which security use cases SIEM can take on, how it can capture and leverage data - structured and unstructured, internal and external - or how to effectively implement a SIEM solution. ![]() Although security information and event management (SIEM) has been around for more than a decade, the solution continues to evolve.
