Integrar Kaspersky Security Center con Wazuh

rokitoh Elastic, Hardening, Kibana, SIEM, thehive, UNIX - *BSD - GNU/Linux, wazuh

Seguimos configurando nuestra infraestructura SIRP Open source (https://red-orbita.com/?p=8726) En esta ocasión veremos como integrar Kaspersky Security Center  para la detección de amenazas con Wazuh y Thehive

Antes de nada, tenemos que ir a la consola de Kaspersky Security Center > Configurar las notificaciones y la exportación de eventos > Configuración exportación a SIEM (Mas información)

Seleccionamos ArcSiht (Formato CEF), Configuramos la dirección ip de nuestro servidor Wazuh Manager y presionamos Aceptar

Una vez configurado el envió de los logs tenemos que acceder a nuestro servidor Wazuh Manager en el cual vamos a generar un Decoder, para ello editamos /var/ossec/etc/decoders/local_decoder.xml

En este archivo agregamos la siguiente configuración

<!-- Kaspersky Decoder. -->

Comprobamos el correcto funcionamiento mediante ossec-logtest

Tras configurar el Decoder procedemos a agregar las siguientes reglas

Reiniciamos el servicio de wazuh manager

systemctl restart wazuh-manager.service

Forzamos una alerta ejecutando algún tipo de software malicioso en un servidor de pruebas. Accedemos mediante nuestro navegador a Kibana y comprobamos  si esta funcionando correctamente nuestro Decoder y las reglas realizadas

En la próxima entrada veremos como integrar estas alertas con Thehive

  2. Hola, tengo una consulta, hice la configuracion tanto en wazuh en centos 7 y el kaspersky windows server, todo exactamente como esta pero no me funciona, incluso el comando /var/ossec/bin/ossec-logtest no me da salida, incluso forzando una salida no obtengo nada y por supuesto en wazuh no obtengo ninguna respuesta, solo tengo salidas de la proteccion por defecto de windows pero ningun log de kaspersky.

    Gracias
