Unos de los errores más graves que se comenten en redes empresariales es la 8.2utilización de DNS externos en configuración de equipos clientes internos cuando se encuentran en un dominio.

Recordemos que para el correcto funcionamiento del Directorio Activo, y la autenticación de los clientes es necesarios que estos lleven en su configuración de interface una dirección de IP de DNS interna ya sea de Windows Server o BIND 8.2.X o superior.

Entonces que pasa con las resoluciones externas para que los usuarios internos puedan navegar a sitios de Internet? Pues aquí es donde empezamos a trabajar con nuestro servidor de DNS Interno.

Veremos en este sencillo ejemplo como configurar reenviadores a los DNS de nuestro proveedor de Internet.

GSM encryption cracked, code available on BitTorrent

It was recently reported that a German computer engineer outlined his plans to to crack GSM encryption and make his results public. Well now, he’s actually done it. The New York Times is reporting that Karsten Nohl has cracked and published the "secret" code used by 3.5 billion of the 4.3 billion wireless connections across the world. The code was developed in 1988 and is used to encrypt 80% of worldwide mobile calls. It is now publicly available via BitTorrent, leaving GSM calls vulnerable to eavesdropping.
It’s important to mention that the A5/1 algorithm that was cracked is the older, and less secure, 64-bit version. A newer, 128-bit A5/3 algorithm, which has been available since 2007, is still un-touched, but unfortunately, GSM carriers have been hesitant in spending the money to adopt the latest standard. Nohl feels that by releasing the code to the public, it will force GSM carriers to finally adopt the newer, more secure, 128-bit encryption. "We are not recommending people use this information to break the law. What we are doing is trying to goad the world’s wireless operators to use better security."
