*Una cacería de amenazas cibernéticas de extremo a extremo generalmente requiere ejecución a través de múltiples fuentes de datos/entornos más pasos de enriquecimiento/ML/visualización en cualquier punto del flujo de caza.

Kestrel es un lenguaje de búsqueda de amenazas que busca hacer la caza de amenazas cibernéticas rápida al proporcionar una capa de abstracción para construir flujos de caza reutilizables, componibles y compartibles. Comenzando con:

Black Hat USA 2024_ para cazar con KestrelCNCF Secure AI Summit 2024_Red Hat Research Quarterly_ (RHRQ)Los desarrolladores de software escriben Python o Swift en lugar de código máquina para convertir rápidamente la lógica de negocio en aplicaciones. Los cazadores de amenazas escriben Kestrel para convertir rápidamente hipótesis de amenazas en flujos de caza. Vemos la caza de amenazas como un procedimiento interactivo para crear sistemas de detección de intrusiones personalizados sobre la marcha, y el flujo de caza es para las cacerías lo que el flujo de control es para los programas ordinarios.

Lenguaje Kestrel: un lenguaje de búsqueda de amenazas para que un humano exprese qué buscar.
Entorno de ejecución Kestrel: un intérprete de máquina que se ocupa de cómo buscar.

Manteniendo la sintaxis del lenguaje de Kestrel 1, rediseñamos completamente el entorno de ejecución de Kestrel 2 para lograr un mejor rendimiento y una sintaxis más flexible con respecto a las representaciones de entidades, atributos y relaciones.
Características clave de Kestrel 2:
Compilación justo a tiempo en lugar de interpretación
Evaluación perezosa y el nuevo comando EXPLAIN
Optimización de Data Lakehouse con consultas profundamente anidadas
Soporte de entidades/atributos OCSF y OpenTelemetry además de STIX
