Abstract
Este documento contiene la ejecución de un ejercicio cuyo objetivo fue aplicar una auditoría al diseño y efectividad de los controles establecidos por la gerencia de Tecnología de Información para el cumplimiento de la ley Sarbanes Oxley. Derivó en una opinión sobre los controles definidos y generó las oportunidades de mejora pertinentes, con el fin de asegurar su eficacia y dar una seguridad razonable de la mitigación de los riesgos respectivos relacionados con TI.
Como parte del alcance, se abarcó un total de tres controles de la cartera definida para TI en la organización, por medio de la ejecución de una prueba de escritorio, una prueba de recorrido del control y una prueba de validación de su efectividad.
Asimismo, se generaron los machotes de papeles utilizados en el ejercicio y se adjuntó dicha información con el objetivo de proporcionar una guía para futuros esquemas de trabajo similares.
A nivel de resultados, se evaluaron tres controles en alcance, los cuales resultaron con una conclusión de “Adecuado en diseño”, y dos controles que se declararon como “Inefectivos en ejecución”, lo cual implicó la recomendación al respecto.
Como parte de las recomendaciones, se generaron diez oportunidades de mejora, orientadas a evitar posibles inefectividades futuras y a mejorar la gestión a nivel de las áreas encargadas.
