70 Tips and Tricks for Mastering the CISSP Exam
by R. Sarma DanturthiLearn how to think and apply knowledge in a practical way. Tackling the CISSP exam is vastly different from simply understanding the subject matter. Even the most experienced security professionals can fail because the questions are tricky and ask the test taker to pick the best of the options given. The CISSP exam conducted by ISC2 is the hardest and most rewarded cybersecurity examination. The test has several domains and sub-domains and covers a wide range of topics on security, including cyber and physical building security fields. It also covers breaches, discovery of breaches, and how to report data breaches. Because the subject area is vast and the questions are almost never repeated, it is hard for the exam taker to memorize or quickly discover the correct solution. The four options given as answers typically have two very close matches to the question. With quick analysis, it is possible to discover from the verbiage of a question what is truly being asked and learn how to find the closest possible solution without spending too much time on each question. What You Will Learn Think outside the box (the CISSP exam demands this of candidates)Quickly discern the gist of a question, eliminate the distractors, and select the correct answerUnderstand the use of words such as MOST, BEST, FIRST, LAST in the questionsSelect the correct answer when multiple options look like possible solutions Who This Book Is For Experienced security practitioners, managers, and executives interested in proving their knowledge across a wide array of security practices and principles, including chief information security officers, chief information officers, directors of security, IT directors and managers, security systems engineers, security analysts, security managers, security auditors, security architects, security consultants, private contractors, and network architects

77 Bloques para Construir una Transformación Digital: Explicación Simplificada
by Jace AnEn 2018, ‘77 Bloques para Construir una Transformación Digital: Modelo de Capacidad Digital’ fue publicado para asistir a los ‘practicantes digitales’ quienes trabajan en el espacio digital. Desde entonces, pocos lectores me han sugerido escribir un libro sobre la transformación digital para ‘el público en general’ que estuviere interesado en aprender más que lo básico sobre la transformación digital. Es así que he creado este libro ‘77 Bloques para Construir una Transformación Digital: Explicación Simplificada’. Este libro intenta entregar los mensajes claves de ‘77 Bloques para Construir una Transformación Digital: Modelo de Capacidad Digital’ al público en general. Dicho esto, este no pretende ser un libro de teoría que discuta las ideas y conceptos académicos de la transformación digital, sino un libro práctico de campo que describe las capacidades digitales probadas como los bloques de construcción para la transformación digital. ‘77 Bloques para Construir una Transformación Digital: Explicación Simplificada’ se enfoca en introducir 77 bloques de construcción para asistir al público en general a comprender las ‘prácticas reales’ en el espacio digital, aunque no cubre totalmente el Modelo de Madurez descripto en detalle en ‘77 Bloques para Construir una Transformación Digital: Modelo de Capacidad Digital’ que asiste a los practicantes digitales con indicadores de madurez de las capacidades digitales. Este libro proporciona unos pocos ejemplos de indicadores de mayor madurez como una introducción al Modelo de Madurez de las Capacidades Digitales.

8-Bit Apocalypse: The True Story Behind The Classic Video Game
by Alex Rubens Jeff GerstmannThe first history of Atari’s Missile Command, and its unforeseen effects on its creators and the culture Before Call of Duty, before World of Warcraft, before even Super Mario Bros., the video game industry exploded in the late 1970s with the advent of the video arcade. Leading the charge was Atari Inc., the creator of, among others, the iconic game Missile Command. The first game to double as a commentary on culture, Missile Command put the players’ fingers on “the button,” making them responsible for the fate of civilization in a no-win scenario, all for the price of a quarter. The game was a marvel of modern culture, helping usher in both the age of the video game and the video game lifestyle. Its groundbreaking implications inspired a fanatical culture that persists to this day. As fascinating as the cultural reaction to Missile Command were the programmers behind it. Before the era of massive development teams and worship of figures like Steve Jobs, Atari was manufacturing arcade machines designed, written, and coded by individual designers. As earnings from their games entered the millions, these creators were celebrated as geniuses in their time; once dismissed as nerds and fanatics, they were now being interviewed for major publications, and partied like Wall Street traders. However, the toll on these programmers was high: developers worked 120-hour weeks, often opting to stay in the office for days on end while under a deadline. Missile Command creator David Theurer threw himself particularly fervently into his work, prompting not only declining health and a suffering relationship with his family, but frequent nightmares about nuclear annihilation. To truly tell the story from the inside, tech insider and writer Alex Rubens has interviewed numerous major figures from this time: Nolan Bushnell, founder of Atari; David Theurer, the creator of Missile Command; and Phil Klemmer, writer for the NBC series Chuck, who wrote an entire episode for the show about Missile Command and its mythical “kill screen.” Taking readers back to the days of TaB cola, dot matrix printers, and digging through the couch for just one more quarter, Alex Rubens combines his knowledge of the tech industry and experience as a gaming journalist to conjure the wild silicon frontier of the 8-bit ’80s. 8-Bit Apocalypse: The Untold Story of Atari's Missile Command offers the first in-depth, personal history of an era for which fans have a lot of nostalgia.
