En mis más de 20 años de experiencia formando a trabajadores he ayudado a cientos de personas a ver al ordenador como una herramienta útil y provechosa. Tengo un ?truco secreto? para conseguirlo y quiero compartirlo contigo. Lo llamo lista de clics. Con el tendras, como en una receta de cocina, los pasos correctos que te permiten, con la simple ayuda de un raton, conseguir ejecutar la tarea sin dudas ni problemas.En este libro encontraras cada una de esas listas, perfectamente explicadas y acompañadas de mas de 800 ilustraciones, para que te sea mas sencillo avanzar. De esta manera, no te perderas y siempre llegaras a tu destino.El mundo informatico ya esta a tu alcance, a solo unos clics. Navegar por Internet, ejecutar el antivirus, crear un documento de word, guardarlo en una carpeta o enviarlo por correo a un destinatario, y muchas otras tareas.No esperes mas. En muy poco tiempo, veras que el ordenador sera ese aliado que siempre has necesitado. ¿Cuando empezamos?

El Internet de los Cuerpos ya está entre nosotros. Estamos construyendo una sociedad híbrida, en la que el código informático y el cuerpo humano se mezclan. Todo se está convirtiendo en un ordenador. Los marcapasos, las bombas de insulina, las pastillas o las lentes de contacto son inteligentes. La creciente interconexion de dispositivos medicos, el uso de conexiones remotas para su mantenimiento y la falta de ciberseguridad hacen que el sector de la salud sea especialmente vulnerable. En estas circunstancias, seria posible obtener acceso no autorizado y manipular el dispositivo del paciente. Varias pruebas realizadas en laboratorios de Estados Unidos demuestran que determinados dispositivos medicos son vulnerables a ciberataques.VIVIMOS EN UN MUNDO EN EL QUE TODO SE ESTA CONVIRTIENDO EN UN ORDENADOR

En nuestra vida cotidiana estamos rodeados de tecnología que incorpora Inteligencia Artificial de forma casi imperceptible. No pensamos en ello cuando consultamos información en Internet —y sin Intel

Ya estamos en la era de los robots al servicio del ser humano. Robots con algo que llamamos inteligencia y que van a ser parte de nuestra vida cotidiana: en casa, en el trabajo, en la calle y ¡formando parte de nuestro propio cuerpo! Pero ¿estan los robots preparados para ser parte de nuestra vida? ¿Estamos los seres humanos preparados para confiar en ellos? ¿Son verdaderamente inteligentes? Este libro, una actualizacion ampliada de la edicion de 2015, pretende acercar los robots a las personas y contribuir a su aceptacion e integracion en la sociedad, descifrando toda su complejidad a traves de una analogia con el propio ser humano y derribando algunos mitos. Al terminar su lectura, se podra distinguir realidad de ficcion, se entendera su funcionamiento y como este puede contribuir a mejorar nuestra calidad de vida, y se conoceran los nuevos avances de la robotica, prestando especial atencion a la interaccion con la inteligencia artificial.

Trust and Records in an Open Digital Environment explores issues that arise when digital records are entrusted to the cloud and will help professionals to make informed choices in the context of a rapidly changing digital economy.Showing that records need to ensure public trust, especially in the era of alternative truths, this volume argues that reliable resources, which are openly accessible from governmental institutions, e-services, archival institutions, digital repositories, and cloud-based digital archives, are the key to an open digital environment. The book also demonstrates that current established practices need to be reviewed and amended to include the networked nature of the cloud-based records, to investigate the role of new players, like cloud service providers (CSP), and assess the potential for implementing new, disruptive technologies like blockchain. Stani and the contributors address these challenges by taking three themes state, citizens, and documentary form and discussing their interaction in the context of open government, open access, recordkeeping, and digital preservation.Exploring what is needed to enable the establishment of an open digital environment, Trust and Records in an Open Digital Environment should be essential reading for data, information, document, and records management professionals. It will also be a key text for archivists, librarians, professors, and students working in the information sciences and other related fields.

The future is now. Acclaimed technologist and inventor Amir Husain explains how we can live amidst the coming age of sentient machines and artificial intelligenceand not only survive, but thrive.Artificial machine intelligence is playing an ever-greater role in our society. We are already using cruise control in our cars, automatic checkout at the drugstore, and are unable to live without our smartphones. The discussion around AI is polarized; people think either machines will solve all problems for everyone, or they will lead us down a dark, dystopian path into total human irrelevance. Regardless of what you believe, the idea that we might bring forth intelligent creation can be intrinsically frightening. But what if our greatest role as humans so far is that of creators?

The book will start talking about the security posture before moving to Red Team tactics, where you will learn the basic syntax for the Windows and Linux tools that are commonly used to perform the necessary operations. You will also gain hands-on experience of using new Red Team techniques with powerful tools such as python and PowerShell, which will enable you to discover vulnerabilities in your system and how to exploit them. Moving on, you will learn how a system is usually compromised by adversaries, and how they hack user's identity, and the various tools used by the Red Team to find vulnerabilities in a system. In the next section, you will learn about the defense strategies followed by the Blue Team to enhance the overall security of a system. You will also learn about an in-depth strategy to ensure that there are security controls in each network layer, and how you can carry out the recovery process of a compromised system. Finally, you will learn how to create a vulnerability management strategy and the different techniques for manual log analysis. By the end of this book, you will be well-versed with Red Team and Blue Team techniques and will have learned the techniques used nowadays to attack and defend systems.
