Windows Event ID Lookup

Comprehensive Windows Event ID reference and lookup service for cybersecurity investigations, detection engineering, incident response and system administration.

Module Overview

The Windows Event ID Lookup module provides instant access to comprehensive information about Windows Event IDs, transforming cryptic event codes into actionable insights for cybersecurity professionals and system administrators. To this day people memorize event ID codes, but the ocean of Windows event logging is much deeper for any one person to understand.

While other tools leave you drowning in obscure event numbers and vague descriptions, this module delivers structured information about all recognised Windows Event log IDs and Providers for different operating system flavours and event log versions.

This level of detail is much needed when we're digging through obscure Windows Event IDs that you may have even never heard of and your tools might not even recognise. Whether you're analyzing security logs, investigating incidents, or developing detections, this module accelerates your understanding of what Windows is actually telling you about system activity, authentication events, and potential security threats. It gives you a short gist of what the event description is from the ETW Provider and what data fields are available.

Use Cases

Security Incident Investigation

  • Rapid Event Triage: Quickly understand the significance of event IDs found in security logs during incident response
  • Event Log Discovery: Quickly search and filter for event logs for different versions of Windows, from different Providers or with specific data fields to accelerate your incident triage

Threat Hunting and Detection Development

  • Detection Rule Creation: Build accurate detection rules by understanding event ID meanings, the data they carry and their contexts
  • Baseline Establishment: Identify normal vs. abnormal event patterns for your environment
  • IOC Validation: Verify if specific event IDs correlate with known attack techniques and tactics
  • False Positive Reduction: Understand event contexts to reduce alert noise and improve detection accuracy

Compliance and Auditing

  • Audit Trail Analysis: Interpret Windows audit events for compliance reporting and security assessments
  • Access Control Monitoring: Understand file access, registry changes, and system modifications
  • Policy Violation Detection: Identify events that indicate security policy violations or unauthorized activities
  • Forensic Timeline Construction: Build accurate timelines using detailed event ID meanings and relationships

Training and Knowledge Transfer

  • Analyst Education: Train junior analysts on Windows event log interpretation and security implications
  • Documentation Creation: Build comprehensive investigation playbooks with accurate event ID references
  • Cross-Team Communication: Provide common language for discussing Windows events across security teams
  • Vendor Coordination: Communicate effectively with Microsoft support using precise event ID knowledge

Usage Guidelines

Search and Lookup Methods

  • Direct Event ID Search: Enter specific event IDs (e.g., "4624", "1102") for immediate lookup
  • Keyword Search: Use descriptive terms like "logon", "process creation", or "registry" to find relevant events

Best Practices for Usage

  • Context Matters: Always consider the event source, channel, and surrounding events for complete understanding
  • Version Awareness: Event ID meanings can vary between Windows versions - check version compatibility
  • Security Focus: Prioritize security-relevant events (4000-4999 range) from the Security audit logs for threat hunting and incident response, but don't forget to look for niche insights in ETW Provider-specific event logs (e.g. Remote Desktop, BITS, etc)
  • Correlation Analysis: Use event relationships and sequences rather than individual events for better detection accuracy

Integration Capabilities (COMING SOON)

  • SIEM Integration: Real-time file reputation checking for security alerts
  • Threat Intelligence Platforms: Export findings to TIP platforms for broader correlation
  • Incident Response Tools: Direct integration with IR platforms and case management systems

Token Pricing Breakdown

Basic Lookup Operations

  • Search or Filter: 1 tokens - ever search or filtering operation returns a maximum of 100 matches and consumes 1 token.

Why These Costs: A minimal token usage is applied to not overcharge customers for the operation and to protect the service from excessive querying implications. An upper limit is put on the returned volume of results, as filtering should take precedence over exploratory work for the prupose of time efficiency.

Performance Expectations

All requests are expected to return a result in the lower milliseconds range depending on network latency.
