Soporte de vulnerabilidades

Servicio de soporte de vulnerabilidades Análisis, notificación y seguimiento de aquellas vulnerabilidades más críticas, que impactan especialmente en las tecnologías empleadas en el sector público. El CCN-CERT trabajará en la recopilación y clasificación de las nuevas vulnerabilidades, realizando un análisis teórico y en laboratorio, cuando sea posible, de aquellas que por su criticidad lo requieran.

Se generarán documentos informativos o “abstracts” de dichas vulnerabilidades y se llevará a cabo un seguimiento de la evolución de la vulnerabilidad en Internet, alertando a los organismos ante cambios en la criticidad, aparición de parches, nuevas recomendaciones, constancia de explotaciones activas, etc.

Para inscribirse en este servicio o recibir más información, escribir al correo electrónico: soporte_acreditacion@ccn.cni.es
