Este libro fue escrito con el propósito de que un principiante pueda aprender de una forma sencilla a programar con el lenguaje C#. Los capítulos van documentados con ejemplos resueltos para poder crear aplicaciones interactivas para Windows, Internet y dispositivos móviles (Description in English below). En definitiva, C# te permitirá crear programas para tu uso personal, para tu grupo de trabajo, para una empresa, aplicaciones distribuidas a través de Internet, aplicaciones de bases de datos, páginas Web y muchas otras funciones. Description in English: C ++ is a programming language designed by Bjarne Stroustrup and made available to developers back in 1985. Its creator's intention was to extend the successful C programming language with mechanisms that allowed object-oriented programming. In that sense, and from an object-oriented languages point of view, C ++ is a hybrid language. That is, C ++ was developed from the C programming language and with few exceptions includes C. This part of C could be compiled under C ++ with no problems.It is currently one of the most popular programming languages for developing general-purpose applications. Like many other languages, it allows working with all types of data, creating data structures, working with files, handling exceptions, etc. Furthermore, C ++ is a language that favors structured programming and allows the development of object-oriented applications. This book has been written with the intention that a beginner can learn in a simple way how to program with the C ++ language. Therefore, all chapters are documented with resolved examples. Finally, once the learning stage has been completed, you can go deeper into the subject by following the recommended bibliography in the prologue of this book.

El objetivo de este libro es introducir al lector en el mundo del pentesting web o hacking de páginas y aplicaciones web. (Description in English below). Se centra en la seguridad de páginas web y el modo de mejorar los niveles de seguridad. Además, podrás conocer las diferentes técnicas de ataque de manera guiada contra aplicaciones web, así como las contramedidas para proteger tus recursos. Desprintion in English: The objective of this book is to introduce readers to the world of Web Pentesting or Hacking of Pages and Web Applications. In it, you will be able to know the different attack techniques in a guided way against Web applications, as well as the recommended countermeasures to protect your resources from this type of attack. Web pages and applications are one of the technologies in the IT world with the highest growth over time. The famous trend of bringing all services to the Web world. It has gone from a small number of Web portals available in the past, to a total presence of all kinds of companies on the Internet, being, today, one of the means of communication capable of providing more effective services between companies and customers. For this reason, this book focuses on the security of this type of Web applications and how to improve security levels. Where the best way to understand your security is to know how attacks are carried out and how their vulnerabilities are exploited.

El libro describe todos los aspectos teóricos relacionados con las redes Wifi, por ejemplo, protocolos, estándares, algoritmos de cifrado, así como los legales, para posteriormente abordar aspectos técnicos relacionados con la seguridad de los diferentes tipos de redes inalámbricas, el equipo de laboratorio y las herramientas a utilizar (Description in English below). Además, incluye una parte dedicada al hacking de las radiocomunicaciones, que pese a ser una de las tecnologías más veteranas, se encuentra en una renovada etapa, dada la aparición de dispositivos como los SDR, que unidos a las nuevas herramientas informáticas desarrolladas, proporcionan una nueva dimensión en el hacking de radiofrecuencia. Description in English: The objective of this book is to introduce readers to the world of security and hacking, specifically in the field of wireless networks, which are present not only in homes or corporate environments, but in a large number of public places, with the which constitute a widely used as well as vulnerable communication channel.Firstly, all the theoretical aspects related to Wi-Fi networks are described, such as protocols, standards, encryption algorithms, as well as the legal ones, and later on, technical aspects related to the security of different types of wireless networks are addressed. Laboratory needed and the tools to be used. This is eminently practical content, which will allow the reader to start from scratch in this exciting world, starting with installing the Kali Linux distribution that will be used for pentesting, and then learning how to correctly manipulate the capture equipment, scanning the means in search of targets, analyze the signal, monitor the traffic and implement the different attacks that can be carried out on open networks, WEP or WPA / WPA2. All the attacks shown in this book are staged step by step, in a practical way, so that the reader can fully reproduce them in a laboratory and acquire the necessary skills to audit the security of this type of network. In addition, this book includes a part dedicated to radio communication hacking, which despite being one of the oldest technologies, is in a renewed stage of splendor, given the appearance of devices such as SDRs, which together with new computer tools developed, they provide a new dimension in radio frequency hacking. It will also detail how to configure and use a low-cost SDR to put into practice the concepts learned and enter this exciting world in a simple and economic way.
