Sicherheit und Vertrauen im Internet: Eine technische Perspektive (essentials)
by Christoph Meinel Harald SackDas globale Internet ist ein offenes Netz, das heißt nicht begrenzt und für jedermann zugänglich. Allerdings hat diese Offenheit ihren Preis: Es gibt keine zentrale Kontrolle, die z. B. Unbefugten Einblick in die Kommunikation und damit in die Privatsphäre anderer Internetnutzer verwehren würde. Um dennoch einen ausreichenden Schutz der Vertraulichkeit und Privatsphäre zu gewährleisten, müssen in eigener Verantwortung Techniken und Tools aus der Kryptografie eingesetzt werden, die Nachrichten verschlüsseln oder deren Unversehrtheit sicherstellen helfen. Die Autoren zeigen unterschiedliche Wege auf, wie der Schutz der Privatsphäre im Internet wiederhergestellt werden kann.
Sicherheit von Webanwendungen in der Praxis: Wie Sich Unternehmen Schu?tzen Ko?nnen -- Hintergru?nde, Maßnahmen, Pru?fverfahren Und Prozesse (Edition Kes Ser.)
by Matthias RohrWebanwendungen bilden in Unternehmen zahlreiche sensible Geschäftsprozesse ab – ob mit Kunden, mit Mitarbeitern, Partnern und Zulieferern. Daher sind Webapplikationen ein Sicherheitsrisiko für Unternehmen und ihr Schutz von entscheidender Bedeutung. In dem Buch beleuchtet der Autor die wichtigsten Aspekte der Webanwendungssicherheit und stützt sich dabei auf seine langjährige Erfahrung als IT-Security-Berater für Webanwendungen und Entwicklungsprozesse.Der Band bietet neben einem allgemeinen Überblick zum Thema Sicherheit von Webanwendungen ausführliche und praxisorientierte Darstellungen zu wichtigen Einzelfragen: Was sind die häufigsten Schwachstellen und mit welchen Maßnahmen lassen sich Webanwendungen am effektivsten gegen Angriffe absichern? Ein eigenes Kapitel befasst sich mit den Verfahren, die eingesetzt werden, um die Sicherheit von Anwendungen bereits im Entwicklungsprozess zu bewerten und zu überprüfen. Der Autor erläutert zudem, wie sich die Sicherheit in selbst entwickelten und zugekauften Webanwendungen durch organisatorische Prozesse nachhaltig verbessern lässt.Die zweite Auflage des 2014 erstmals erschienen Buchs wurde vor dem Hintergrund neuer Techniken zur Abwehr von Angriffen und neuer Prüfverfahren vollständig überarbeitet und aktualisiert. Auch aktuelle Beratungsprojekte des Autors haben Eingang in die Neuauflage gefunden – insbesondere dort, wo es um organisatorische Aspekte von Webanwendungssicherheit geht.Der Band richtet sich an Entwickler von Webanwendungen, IT-Security- und Qualitätsmanager genauso wie an Leser, die sich in das Thema Webanwendungssicherheit einarbeiten wollen.

Los siete hábitos de la gente desinformada: Cómo informarse y tomar decisiones en las redes sociales
by Marc Argemí BallbéVivimos el espejismo de creer que, como hemos consultado internet, estamos lo suficientemente informados para tomar buenas decisiones. Sin embargo, esta idea es errónea. Este libro permite identificar los hábitos que nos hacen más vulnerables a la desinformación en el entorno digital y ofrece las herramientas para decidir por nosotros mismos tanto en el terreno personal como profesional. Estar bien informado significa contar con suficientes datos para, de entre todas las decisiones posibles, poder elegir una. Sin embargo, la experiencia nos demuestra que muchas decisiones tomadas con seguridad están lejos de sustentarse en los datos, circunstancia que explica que podamos parecer al mismo tiempo unos perfectos ignorantes y muy decididos. Internet y las redes sociales han llevado esta problemática hasta el extremo. Nunca antes habíamos tenido acceso a tanta información, aunque esto no implica que seamos capaces de escoger mejor. Los algoritmos del entorno digital (donde conviven webs, Facebook, Instagram, Twitter o WhatsApp) no siempre están programados para ayudarnos a elegir de forma adecuada. Tenemos la engañosa percepción de que estamos bien informados y, por ello, decidimos correctamente. No obstante, la desinformación nos afecta en nuestra vida personal y profesional. ¿Soy víctima de este fenómeno? La respuesta, con toda probabilidad, sería afirmativa porque nos desinformamos con facilidad y de modos muy diversos. El objetivo de este libro es ayudar a identificar los hábitos que nos hacen más vulnerables: el cuñadismo, la incredulidad crédula, la indecisión crónica, la ansiedad, el confusionismo relacional, el activismo visceral y la precariedad informativa. Y, con sus herramientas prácticas para contrarrestar la desinformación, será de utilidad tanto para los expertos en redes sociales y profesionales de la gestión de cuentas en Twitter como para aquellas personas que solo visitan las páginas web de los periódicos de toda la vida.
Sign of the Apocalypse: Ruminations and Wit from an American Roadside Prophet
by John GetchellFriends, neighbors, and passersby from all over the country can’t fail to miss “The Sign’s constantly changing humor and insight. On occasion, The Sign of the Apocalypse (SOTA) traffics in the earnest, but at its heart is rooted in a deep-seated desire to express the sarcastic and snort-worthy. This, and a love of haiku, pizza, Latin, double entendre, and the worst puns ever crafted. Two years in the making, the message on “The Sign” is changed on a daily basis, with the primary benefit of slowing passing traffic to a honking crawl. It was designed to convey pithy tidbits of thought and wordplay. In its conception, SOTA was perpetrated in spite of the objection of the author's girlfriend, and with hopes of creating controversy and dismay in the local community. The girlfriend packed up and left, and the community and town fathers were surprisingly gruntled by the proceedings. Punny and sarcastic signs include: • When attacked by a gang of clowns, go for the juggler • What if doing the hokey pokey really is what it’s all about? • Legalize marinara • A penny saved is ridiculous • Wendy, please take me back / I’m so miserable / it’s almost like / you’re still here
The Signal: The History of Signal Processing and How We Communicate
by Ted LewisComputers are the foundation of the information age, but communication technology is the foundation of the foundation. Without the theories and practical applications of theory brought to us by the pioneers of communication, the computer age would perhaps have remained in the back office, hidden away as infrastructure like electricity or running water – critical to modern life, but not as transforming as the combination of communications and computing. The information age exploded once machines were endowed with the ability to talk among themselves. The Signal connects everything to everything else, in both communication, and in the metaphorical sense as the link between and among people. Features Identifies the key ideas underlying modern communications technology, and documents the contributions of its inventors Explores the signal in communication, and also in the metaphorical sense as the link between and among people Leads the reader through a journey from ancient number systems to Voyager II to radio and MP3s to quantum cryptography Includes coverage of "Signals from Hell," including memes and "fake news" on the Internet Looks to the future of communication, with emergent 5G
