SCADA Systems can be seen as a fundamental component in Critical Infrastructures, having an impact in the overall performance of other Critical Infrastructures interconnected. Currently, these systems include in their network designs different types of Information and Communication Technology systems (such as the Internet and wireless technologies), not only to modernize operational processes but also to ensure automation and real-time control. Nonetheless, the use of these new technologies will bring new security challenges, which will have a significant impact on both the business process and home users. Therefore, the main purpose of this Chapter is to address these issues and to analyze the interdependencies of Process Control Systems with ICT systems, to discuss some security aspects and to offer some possible solutions and recommendations.

A. Nieto, and G. Fernandez, "Sistema Colaborativo de Detección y Reacción ante Intrusiones basado en Intel vPro",

En este trabajo proponemos una plataforma para el desarrollo de un sistema colaborativo para la detección y reacción ante intrusiones, empleando como base las tecnologías presentes en Intel vPro. La solución presentada está dirigida a solventar la necesidad de implantación de nuevas tecnologías que posibiliten la reacción ante ataques, independientemente del sistema operativo usado. Con este fin, en este trabajo abordamos tres puntos fundamentales: la detección de intrusiones colaborativa, la respuesta automática de los nodos ante la detección de una intrusión y el uso de herramientas que posibiliten asegurar la confianza en un nodo. En un sistema colaborativo como el que se propone aquí, un aspecto clave para la seguridad es la protección de las comunicaciones entre los mecanismos de detección y reacción frente a intrusiones. La modificación o el simple acceso a los datos intercambiados por tales sistemas supone un grave riesgo para la seguridad del entorno. Como resultado hemos desarrollado un prototipo preliminar para probar la solución propuesta en un escenario de ataque real.

When a Supervisory Control and Data Acquisition (SCADA) system monitors and manages other complex infrastructures through the use of distributed technologies, it becomes a critical infrastructure by itself: A failure or disruption in any of its components could implicate a serious impact on the performance of the other infrastructures. The connection with other systems makes a SCADA system more vulnerable against attacks, generating new security problems. As a result, it is essential to perform diverse security analysis frequently in order to keep an updated knowledge and to provide recommendations and/or solutions to mitigate or avoid anomalous events. This will facilitate the existence of a suitable, reliable, and available control network.
