Information Warfare Monitor The Information Warfare Monitor (IWM) was an advanced research activity tracking the emergence of cyberspace as a strategic domain. It closed January 2012. It was a public-private venture between two Canadian institutions: The SecDev Group, an operational think tank based in Ottawa (Canada), and the Citizen Lab at the Munk School of Global Affairs, University of Toronto. The Principal Investigators and co-founders of the Information Warfare Monitor are Rafal Rohozinski (The Secdev Group) and Ronald Deibert (Citizen Lab). The Information Warfare Monitor is part of the Citizen Lab’s network of advanced research projects, which include the OpenNet Initiative, the Fusion Methodology Centre, and PsiLab. It was an independent research effort and its stated mission was to build and broaden the evidence base available to scholars, policy makers, and others. History[edit] Activities[edit] The Information Warfare Monitor engages in three primary activities Case studies. Field-based investigations.
WinRoute :: Example of VPN tunnel configuration This chapter provides a detailed exemplary description on how to create an encrypted tunnel connecting two private networks using the Kerio VPN. This example can be easily customized. Note: This example describes a more complicated pattern of VPN with access restrictions for individual local networks and VPN clients. An example of basic VPN configuration is provided in the Kerio WinRoute Firewall Step By Step Configuration document. Specification Supposing a company has its headquarters in New York and a branch office in Chicago. The server (default gateway) of the headquarters uses the public IP address 63.55.21.12 (DNS name is newyork.company.com), the server of the branch office uses a dynamic IP address assigned by DHCP. The local network of the headquarters consists of two subnets, LAN 1 and LAN 2. The network of the branch office consists of one subnet only (LAN). VPN clients can connect to the LAN 1 and to the network of the branch office. Headquarters configuration VPN test
Researchers Discover Twitter-Controlled Bitcoin Bot F-Secure has discovered a bot that commands Twitter accounts to help in the generation of Bitcoins. Security firm F-Secure has discovered a bot that compromises Twitter accounts to help in the generation of Bitcoins. Bitcoin is a decentralized virtual currency that was formed by programmers in 2009, and is generated by programming computers to calculate highly complex math problems. The more computing power you have, the faster you can create Bitcoins; this is why Bitcoin rigs often look like massive sculptures of connected servers. According to an F-Secure blog post, the Twitter-based command below generates a bot that can control the Twitter user's computer and add it to a bitcoin mining rig. Last month Symantec blogged about the potential of creating botnets used to mine bitcoins, without the computer owner ever knowing. Bitcoin has found fans in libertarians, hackers of all shades, computer programmers, and more. For more, see "Which Bitcoin Exchange Can You Trust?"
Aplicaciones en capas La estrategia tradicional de utilizar aplicaciones compactas causa gran cantidad de problemas de integración en sistemas software complejos como pueden ser los sistemas de gestión de una empresa o los sistemas de información integrados consistentes en más de una aplicación. Estas aplicaciones suelen encontrarse con importantes problemas de escalabilidad, disponibilidad, seguridad, integración... Para solventar estos problemas se ha generalizado la división de las aplicaciones en capas que normalmente serán tres: una capa que servirá para guardar los datos (base de datos), una capa para centralizar la lógica de negocio (modelo) y por último una interfaz gráfica que facilite al usuario el uso del sistema. Figura 3.1. Si intentamos aplicar esto a las aplicaciones web, debido a la obligatoria sencillez del software cliente que será un navegador web, nos encontramos con una doble posibilidad: La arquitectura MVC y Model 2
Heroku | Cloud Application Platform TEL&PC Ltda. La Red Privada Virtual (RPV), en inglés Virtual Private Network (VPN), es una tecnología de red que permite una extensión de la red local sobre una red pública o no controlada, como por ejemplo Internet. Ejemplos comunes son, la posibilidad de conectar dos o más sucursales de una empresa utilizando como vínculo Internet, permitir a los miembros del equipo de soporte técnico la conexión desde su casa al centro de cómputo, o que un usuario pueda acceder a su equipo doméstico desde un sitio remoto, como por ejemplo un hotel. Todo ello utilizando la infraestructura de Internet. Para hacerlo posible de manera segura es necesario proporcionar los medios para garantizar la autenticación, integridad y confidencialidad de toda la comunicación: Autenticación y autorización: ¿Quién está del otro lado? Integridad: La garantía de que los datos enviados no han sido alterados.
Amazon Web Services Redes - Arquitectura Cliente/Servidor en 3 niveles Abril 2014 Introducción a la arquitectura en 2 niveles La arquitectura en 2 niveles se utiliza para describir los sistemas cliente/servidor en donde el cliente solicita recursos y el servidor responde directamente a la solicitud, con sus propios recursos. Introducción a la arquitectura en 3 niveles En la arquitectura en 3 niveles, existe un nivel intermediario. Un cliente, es decir, el equipo que solicita los recursos, equipado con una interfaz de usuario (generalmente un navegador Web) para la presentaciónEl servidor de aplicaciones (también denominado software intermedio), cuya tarea es proporcionar los recursos solicitados, pero que requiere de otro servidor para hacerloEl servidor de datos, que proporciona al servidor de aplicaciones los datos que requiere Comparación entre ambos tipos de arquitecturas Arquitectura de niveles múltiples En la arquitectura en 3 niveles, cada servidor (nivel 2 y 3) realiza una tarea especializada (un servicio).

Aplicaciones ERP: Sistema de Gestión Integrado La gestión clásica de información en una empresa poco moderna, suele aplicar un software diferente en cada departamento: finanzas, almacenes, recursos humanos, etc. Las inevitables consecuencias de dicha dispersión de datos y formatos dan lugar a una pérdida de tiempo e información de incalculable valor y a la larga es más costoso no adoptar un sistema integrado que seguir en la misma situación. Por ejemplo, si un cliente hace un pedido al departamento de ventas, éste lo registrará en un sistema de información exclusivo de ventas; en consecuencia, ni el departamento de finanzas podrá controlar si dicho cliente tiene un crédito, ni el departamento de almacenes podrá verificar si existe material suficiente para poder suministrar el pedido. Por tanto, estos datos tendrán que comunicarse por vía telefónica o por medio de un documento escrito a los respectivos departamentos para que éstos realicen sus labores y cumplan con culminar el ineficiente proceso de la venta. 1. 2. 3. 1. 2. 3. 4. 1.
Object-oriented programming Overview[edit] Rather than structure programs as code and data, an object-oriented system integrates the two using the concept of an "object". An object has state (data) and behavior (code). Objects correspond to things found in the real world. So for example, a graphics program will have objects such as circle, square, menu. The goals of object-oriented programming are: Increased understanding.Ease of maintenance.Ease of evolution. The overall understanding of the system is increased because the semantic gap—the distance between the language spoken by developers and that spoken by users—is lessened. Object-orientation takes this to the next step. In addition to providing ease of maintenance, encapsulation and information hiding provide ease of evolution as well. An object-oriented program usually contains different types of objects, each corresponding to a real-world object or concept such as a bank account, a hockey player, or a bulldozer.

HDfury.com Future Media Concepts - Authorized Apple, Adobe, Autodesk, Avid, and NewTek Training by Certified Instructors 2.5D 2.5D ("two-and-a-half-dimensional"), ¾ perspective and pseudo-3D are terms, mainly in the video game industry, used to describe either 2D graphical projections and similar techniques used to cause a series of images (or scenes) to simulate the appearance of being three-dimensional (3D) when in fact they are not, or gameplay in an otherwise three-dimensional video game that is restricted to a two-dimensional plane. Common in video games, these projections have also been useful in geographic visualization (GVIS) to help understand visual-cognitive spatial representations or 3D visualization.[1] The terms ¾ perspective and ¾ view trace their origins to portraiture and facial recognition, where they are used to describe a view of a person's face which is partway between a frontal view and a side view.[2] Computer graphics[edit] Axonometric & oblique projection[edit] Lincity tiles 2D axonometric graphical elements to create a 2.5D game environment.
