5 Actualmente el Banco de la Nación a través de su División Seguridad de Información, otorga accesos en forma independiente utilizando los módulos de seguridad de cada una de las aplicaciones y/o plataformas tecnológicas. Además, el registro de nuevos usuarios se realiza a través de una comunicación formal desde el Departamento de Personal a la División Seguridad de Información, esta forma de trabajo ocasiona que no se lleve un control estricto del ciclo de vida de la gestión de identidad, las cuentas de los usuarios y la normativa actual vigente, tal como la circular SBS G-140; todo esto trae como consecuencia un incremento en el riesgo sobre la confidencialidad, disponibilidad e integridad de la información del Banco. El Banco de la Nación cuenta en la actualidad con 5,500 usuarios a nivel nacional y con 250 aplicaciones implementadas. El presente proyecto tiene como objetivo principal administrar eficientemente los accesos a las aplicaciones del Banco de la Nación mediante la implementación de un Sistema de Administración de Accesos e Identidades, puesto que a través de una eficiente gestión de los accesos a las aplicaciones, se espera obtener un mayor control sobre los activos de información ) 5 2

7 +, +, +, +, Nowadays the National Bank through its Information Security Division provides an independent access by using security modules of each application and / or technology platforms. Furthermore, registration of new users is done through a formal communication from Personnel Department to Information Security Division, this kind of work made difficult a strict control about the life cycle of identity management, the user accounts and the laws currently in force, such as regulation SBS G-140; all of this increases risk of confidentiality, availability and integrity of the Bank. Currently, the National Bank has 5,500 nationwide users and 250 implemented applications. The main objective of this project is to manage efficiently the access to applications belong to the National Bank, which is made through the implementation of an Access and Identity Management System, as through an efficient management of access to applications, it is expected to obtain a greater control over information assets ) 5 2 -
