Para aquellos que requieran un documento de todos los boletines de seguridad emitidos por Microsoft, les recomiendo entrá AQUI en donde encontrarán las fechas y los artículos con las diferentes actualizaciones desde el año 2006. Les recordamos que excepto las actualizaciones publicadas fuera de fecha, los boletines de Microsoft son publicados el segundo martes de cada mes.

Si no cuenta con una herramienta de despligue para las actualizaciones, y requiere su implementación, recuerde que puede utilizar el MBSA y el WSUS (verificar y desplegar) siendo ámbos productos de descarga gratuita de Microsoft. Es importante que la compañía cuente con una política de actualización de software, sobre todo aquellas actualizaciones marcadas como "Windows Security". No realice actualizaciones masivas y actualice por el simple hecho de actualizar. Verifique su entorno, chequee la documentación de las actualizaciones y como impacta en su infraestructura. Recuerde que si posee conectores de base de datos, tenga cuidado de actualizar los drivers de conexión como ODBC, ya que una nueva versión puede provocar que su sistema no se comporte adecuadamente.
Otro punto para tener en cuenta en la actualización, es que DEBE verificar si una vez implementado requiere un reinicio de la aplicacion o del servidor. Trate de optimizar la entrega de servicios, planificando adecuadamente su implementación. La actualización se hace efectiva, una vez reiniciado el servicio o servidor. LEA ATENTAMENTE LAS RECOMENDACIONES DE LA ACTUALIZACION.

Por último, no fuerce la instalación de una actualización si la misma genera un error o da problemas en la instalación. Lea la documentacion.

Plataforma actualizada, plataforma segura....

Hasta la próxima....
