Jibril: The Theory and Mission Behind It¶

Introduction¶

Jibril mission: to deliver real-time insights with minimal overhead while maintaining robust security and reliability.

Comprehensive Resource Tracking¶

Jibril monitors a wide range of system resources to ensure no critical detail is missed:

• Users and Groups
• Machines, Hostnames, and Namespaces
• Disks, Filesystems, Volumes, and Files
• Containers, Processes, and Threads
• Protocols, Domains, Ports, and Sockets
• Network Flows

This exhaustive tracking provides the foundation for deep, actionable insights into system activity and behavior.

Powerful Resource Management¶

Jibril captures every interaction with system resources, ensuring a complete audit trail for security and operational monitoring. Tracked actions include:

• Creation and Destruction
• Modification through Truncate, Link, Rename, Open, and Close
• Data Access via Read, Write, Seek, and Execute
• Memory Mapping (Map) and Synchronization (Sync)
• Locking (Lock)

These detailed logs empower teams to analyze and respond to changes across their infrastructure with confidence.

Key Features and Innovations¶

Jibril is purpose-built to address the most critical needs of modern runtime monitoring and security. Its core innovations include:

1. Data Immutability: Ensures data integrity by preventing any alteration after capture, providing a trusted source for forensic analysis.
2. Non-Reliance on Circular Buffers: Avoids traditional circular buffers, eliminating bottlenecks and reducing complexity in data handling.
3. Real-Time Event Delivery: Ensures immediate access to events for timely detection and response to threats.
4. Integrated Kernel Status: Acts as an all-in-one introspection and tracing tool with full in-kernel state awareness.
5. Kernel Query Language (KQL): Allows precise data retrieval through direct queries to in-kernel data, enabling advanced analysis.
6. Query Caching: Enhances performance by caching frequently queried data, leveraging data immutability for faster results.
7. Rule-Based Detection: Dynamically matches rules in-kernel for proactive threat detection and rapid response.
8. Third-Party Integration: Supports plugins for external data stores (e.g., SQLite) to enable seamless data management and integration with other systems.

These features work together to deliver cutting-edge performance while simplifying complex monitoring tasks.

Efficient Information Acquisition¶

Jibril excels in collecting and processing critical system data through three streamlined methods:

1. Queries: Perform inventory checks and fingerprinting by querying in-kernel stores, enabling rapid insight into system state.
2. Micro Events: Capture highly efficient, minimalistic events containing only timestamps, flags, and keys, reducing overhead.
3. Detections: Use interval-based queries to in-kernel data for proactive and continuous threat detection.

These mechanisms ensure Jibril operates with precision and speed, even under demanding workloads.
