Personalmente me gusta usar distribuciones LTS por varias razones. Cuando Canonical publicó la versión 12.04 LTS, me actualicé desde la 10.04 LTS, la que funcionó muy funcionó durante esos 2 años. Después de actualizarme a 12.04 LTS (reinstalé, para ser más exactos) me llevé algunas desagradables sorpresas, y no porque no me gustara Unity, sino porque cosas como la conexión de 2 monitores externos no funcionaba, al menos a mi no me funcionaba. Llegué a la conclusión que el problema era del pobre soporte 3D de los drivers ATI que tenía.

The Amnesic Incognito Live System o quizás más conocido como TAILS, es un sistema operativo de estos que puedes arrancar y usar desde un DVD, lápiz USB, tarjeta de memoria, etc. Más conocido como sistema vivo o Live.

La principal característica de este sistema operativo es que está construido con la privacidad como pilar principal. Es un sistema Linux basado en Debian y que integra varias herramientas ya configuradas para usar la red Tor, GPG, OTR (Off The Record), cifrado de discos y particiones (LUKS), etc.

El CERT mantiene una lista de reglas y buenas prácticas que recomiendan seguir cuando escribimos código en el lenguaje de programación Java de Oracle. La versión 1.0 de esta lista se apoya en las versiones 1.6 y 1.7 de Java.

La lista se divide en las siguientes secciones:

• 00. Input Validation and Data Sanitization (IDS)
• 01. Declarations and Initialization (DCL)
• 02. Expressions (EXP)
• 03. Numeric Types and Operations (NUM)
• 04. Object Orientation (OBJ)
• 05. Methods (MET)
• 06. Exceptional Behavior (ERR)
• 07. Visibility and Atomicity (VNA)
• 08. Locking (LCK)
• 09. Thread APIs (THI)
• 10. Thread Pools (TPS)
• 11. Thread-Safety Miscellaneous (TSM)
• 12. Input Output (FIO)
• 13. Serialization (SER)
• 14. Platform Security (SEC)
• 15. Runtime Environment (ENV)
• 16. Java Native Interface (JNI)
• 49. Miscellaneous (MSC)
• 50. Android (DRD)

Como podemos ver la última sección de la misma está orientada a Android, en la que se comentan los siguientes temas:

• DRD00-J. Do not store sensitive information on external storage (SD card)
• DRD01-J. Limit the accessibility to your sensitive content provider
• DRD02-J. Do not allow WebView to access sensitive local resource through file scheme
• DRD03-J. Do not broadcast sensitive information using an implicit intent
• DRD04-J. Do not log sensitive information
• DRD05-J. Do not grant URI permissions on implicit intents
• DRD06-J. Do not act on malicious intents
• DRD07-J. Protect exported services with strong permissions
• DRD08-J. Always canonicalize a URL received by a content provider
• DRD09-J: Restrict access to sensitive activities
• DRD10-J. Do not release apps that are debuggable
• DRD11-J. Ensure that sensitive data is kept secure
• DRD12-J. Do not trust data that is world writable
• DRD13-J. Do not allow JavaScript in Web Apps
• DRD14-J. Check that a calling app has appropriate permissions before responding
• DRD15-J. Consider privacy concerns when using Geolocation API
• DRD16-J. Explicitly define the exported attribute for private components
• DRD17-J. Do not use the Android cryptographic security provider encryption default for AES
• DRD18-J. Do not use the default behavior in a cryptographic library if it does not use recommended practices
• DRD19-J. Properly verify server certificate on SSL/TLS

Si eres de los que prefieres un libro, The CERT Oracle Secure Standard for Java (imagen que encabeza esta entrada), es una buena opción, aunque no cubre el apartado de Android, al menos en la revisión actual.

Un editor hexadecimal es una de las herramientas que siempre es bueno tener a mano. Recuerdo usar este tipo de herramientas en mis tiempos de Spectrum y Amiga para cambiar el texto que aparecían en los juegos. Una tontería, pero me divertía :)

El editor que actualmente uso es wxHex Editor. Aunque yo personalmente prefiero usar aplicaciones locales, también me gusta tener a mano herramientas online, porque nunca se sabe en que sistema te vas a encontrar y que herramientas vas a necesitar.
