SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill detects subtle, gradual changes in device process execution behavior that may indicate unauthorized activity or misconfigurations, which traditional alerts often miss.

Core Features & Use Cases

  • Behavioral Baseline: Establishes a normal process execution baseline for devices.
  • Drift Scoring: Computes a weighted score across Volume, Processes, Accounts, Process Chains, and Signing Companies to quantify deviation.
  • Fleet-wide & Single-Device Modes: Analyzes entire device fleets or focuses on specific endpoints.
  • Corroboration: Integrates with SecurityAlerts and DeviceInfo for comprehensive analysis.
  • Use Case: Identify if a server has started executing new, unexpected processes or command-line patterns over time, which could signal a slow-moving compromise or a misconfigured automation script.

Quick Start

Investigate process drift on the device named 'WEBSRV-01' over the last 7 days.

FAQPage Schema
How do I detect process drift on an endpoint device?

Endpoint process drift is detected by analyzing DeviceProcessEvents against a configurable time window to establish a behavioral baseline and identify new processes, command-line patterns, and account usage deviations.

What is behavioral baseline deviation in device security?

Behavioral baseline deviation is the quantification of process execution changes over time, scoring volume, processes, accounts, process chains, and signing companies to identify subtle unauthorized activity or misconfigurations.

Can I analyze process drift across a large fleet of devices?

Fleet-wide analysis is supported with tiered depth for large environments, allowing you to monitor process execution baseline deviations across an entire device fleet or focus on specific endpoints.

Does endpoint process drift detection integrate with existing security alerts?

Drift detection corroborates findings by integrating with SecurityAlerts and DeviceInfo, providing a comprehensive risk assessment that combines baseline deviations with existing security alert data.

How do I investigate unexpected command-line patterns on a specific server?

You can investigate unexpected command-line patterns by running single-device analysis on a named endpoint over a specific time window to identify new processes and account usage that signal slow-moving compromise.

What are the limitations of device process drift detection?

Detection relies on DeviceProcessEvents data availability and configurable time windows, meaning short windows may miss slow-moving compromises while large fleets require tiered depth to manage performance.
