The imperative to defend against cyber threats is a fact of life in the digital age. World governments, Silicon Valley, and Wall Street all agree that their sensitive and proprietary data needs to be protected from bad-faith actors. We have all seen headlines decrying Russian hackers, North Korea infiltrating Sony Pictures, and controversial names like Snowden, Assange, and Manning. But cybersecurity isn't just a concern for Pentagon officials and business tycoons. If you've used your phone, opened your laptop, or checked your email today, you are a participant in the world of cybersecurity. We've all received phishing emails, been alerted of suspicious logins, and questioned why a "strong password" needs all those letters, numbers, and special characters. And yet, even though cybersecurity is such a central part of modern life, it's practically unintelligible to the non-techie. In this enlightening and accessible new book, Pablo Brum closes the gap between high-minded concepts and the day-to-day skills and strategies that readers need to know to stay safe in the digital world.
