La seguridad de un software no es un software de seguridad. Nos preocupamos de cuestiones como la autenticación, el control de acceso, la confidencialidad, la criptografía y la gestión de privilegios.

Azure Ansible Misconfiguration: Improper Security Group Network Access Control

YAML

Abstract

La tarea de Ansible define un grupo de seguridad de red que permite el acceso a los servicios administrativos.

Explanation

Las configuraciones demasiado amplias exponen los sistemas y amplían la superficie de ataque de una organización. Los servicios abiertos a la interacción con el público están sujetos a análisis y sondeos casi continuos por parte de los atacantes.

Esto es especialmente problemático cuando se descubre y publica una vulnerabilidad de día cero para un servicio expuesto (por ejemplo, Heartbleed). Los atacantes pueden perseguir y buscar activamente sistemas expuestos y sin revisión que puedan aprovechar.

Ejemplo 1: La siguiente tarea de Ansible de ejemplo permite el tráfico entrante sin restricciones a una variedad de puertos, incluido el puerto de servicio RDP (3389).
