Harvard CS50’s Intro to Cybersecurity – Full University Course

This course is CS50's introduction to cyber security and is for both technical and non-technical audiences . It's taught by one of the world's most loved computer science teachers , Dr. David J. Men from Harvard University . You will learn how to secure your accounts, data, systems, and software against today's threats and how to recognize and evaluate tomorrow's threats as well , both at home and at work . You will learn how to preserve your own privacy and how to view cyber security not in absolute terms but relative a function of risks and rewards for an adversary and costs and benefits for you . Dr. Mail presents both highlevel and low-level examples of threats , providing students with all they need to know technically to understand both . [music] speaking, have to be locked . But an adversary has to find just one mistake that we've made, a single door or window, a jar . So perhaps we should be focused not only on prevention but on detection especially through auditing through monitoring so that even if an adversary gets in we can at least detect as much quickly and minimize the downsides for us and in turn the upsides for them . Perhaps nowadays tools like artificial intelligence or AI can even help with that detecting patterns and potential adversaries behavior that we might not even notice ourselves. And . And perhaps if we raise the bar high enough for the adversary , increasing their cost, their risk , decreasing their potential reward , they'll simply lose interest in us as a target . Of course, if they have more resources than us , they might very well win anyway
