SIEM software collects and aggregates log data generated throughout the entire IT infrastructure, from cloud systems and applications to network and security devices, such as firewalls and antivirus. SIEM then identifies, categorizes, and analyzes incidents and events. SIEM analytics delivers real-time alerts, dashboards, and reports to several critical business and management units. Modern SIEMs also apply unsupervised machine learning to enable anomaly detection (User and Entity Behavior Analytics) to the collected log data.
Enterprises must monitor and guard their data to protect themselves from increasingly advanced cyber threats in the digital economy. The chances are that your company has more data to collect and analyze than ever before. With exploding data volumes and increasing complexity, as IT infrastructures converge towards hybrid deployments between cloud and on-prem, it is increasingly important to have a central security solution to track behavior and critical events.
SOC teams thrive when there is less of a burden on them to perform – they need clarity. Without SIEM, security analysts must go through millions of disparate and siloed data for each application and security source. In short, SIEM can accelerate detection and response to cyber threats – making security analysts more efficient and accurate in their investigations.
SIEM software aids speed and accuracy in response to security incidents and provides centralized collection, classification, detection, correlation, and analysis capabilities. This makes it easier for teams to monitor and troubleshoot IT infrastructure in real-time.
However, the industry’s lack of skilled resources means that security events can overburden analysts and Security Operation Centers (SOCs), resulting in alert fatigue and confusion about prioritizing the company’s security resources.
SIEM tools have been around since 2005, but the SIEM definition and the answer to “what is SIEM?” have evolved since then. Changes in the threat landscape have created a need to identify a wider variety of threats quickly. For years, SIEM solutions were implemented to help security and IT teams analyze security alerts in real-time. Still, many traditional SIEM solutions cannot gather and analyze substantial amounts of data from various sources.
Due to the exponential growth of data volume, many organizations face limited value at increasing costs. Those who use SIEM, where the licensing model is based on data volume, must select which data to ingest to not vastly exceed their budget. In the case of breaches, this can mean missing data you need or can leave your organization completely blind to abnormal behavior in critical systems.
At the same time, there is a shortage of security analysts available in the labor market. Security operations teams struggle to keep up with the deluge of security alerts from a growing arsenal of threat detection technologies while relying on rule-based manual procedures for operations. Fortunately, advanced analytics, investigation, and response tools combined with developments in machine learning create new efficiencies in SIEM solutions that help remedy the cybersecurity skills gap.
The critical role of SIEM
To provide monitoring, detection, and notification of security events or incidents within an IT environment. It provides a comprehensive and centralized view of the security posture of an IT infrastructure and provides cybersecurity professionals with insights into the activities within their IT environment.
Converged SIEM helps SOC teams combine data sets from multiple sources. Instead of using multiple standalone products, they now have one single source of truth. Converged SIEM is the only unified platform that delivers SIEM+SOAR, UEBA, endpoint security, and BCS for SAP capabilities as a service directly to enterprises and MSSPs – all from a single plane of glass.
SOAR is an innovative security orchestration, automation, and response (SOAR) solution that brings cybersecurity efficiency and effectiveness to businesses.
Pairing SIEM with SOAR combines security monitoring and incident response to help security staff quickly respond to and resolve incidents. A SOAR solution automates actions and responses, handling incidents that don’t need the security team’s attention.
