Windows events provide a wealth of security-relevant information, especially when they are correlated and analyzed within a SIEM like IBM QRadar. Whether you rely on MITRE ATT&CK, NIST, or another security framework, Windows Events are likely one of your higher volumes (EPS – Events Per Second) and represent your largest-sized events (Gigs per day – Storage and Archive).
Maintaining a healthy security practice requires all events are available for Offences/Alerts Correlation, Threat Detection, and Threat Hunting. While Windows Events are undeniably valuable to security analysts and tools, they pose unique challenges for security teams to successfully manage Collection and Control volume while managing budgets, resources, and time.
There are many ways to collect Windows Events for QRadar. Popular methods include agents like WinCollect (IBMâs Agent), and Windows Event Collection/Forwarding (WEC/WEF), which is a feature built into Microsoft. Each method offers unique administrative challenges and tradeoffs and must be carefully evaluated.
Cribl Stream can integrate with your collection mechanism and sometimes displace Syslog deployments and Windows Event Collection/Forwarwarders (WEC/WEF).
Windows Events are broken down into EvenetIDs and Subtypes. Thankfully, each event is well documented, and resources like ultimatewindowssecurity.com can provide insight into a given eventâs value to a security team.
Not all EventIDs drive value for Security, yet they are frequently sent to the SIEM, driving up costs and consuming valuable Events Per Second (EPS) resources. Worst yet, some events may be sent to the SIEM to satisfy another team’s needs for compliance purposes only.

Cribl Stream enables administrators to selectively control the routing, suppression, and dropping of events before they reach QRadar. This allows teams to satisfy the needs of their security practice while routing nonsecurity events to another destination.
Microsoft Windows Security Events are natively supported by QRadar using the included DSM (Devise Support Module). This means parsing events and mapping them to threat models within QRadar are ready to go out of the box! We will use this to our advantage đ.
For the guide below, we will use IBMâs WinCollect Agent to collect Windows events, and forward them to Cribl Stream to be sent to QRadar. Because Cribl Stream is in the middle, events can be evaluated, transformed, and routed selectively. Weâll also use the âQRadar Pack for Windowsâ to drop and suppress events that typically drive very little value for a security team.
NOTE: Carefully review which events you are dropping before deploying to production!
Check Criblâs Live Capture to ensure events are flowing
Check QRadar Log Activity to ensure events are received.
Controlling Events
