About this courseSkip About this course
Information Security is everywhere: as the world becomes more and more digitized, so it becomes more and more hackable. Cyber attacks, data breaches, and even cyber warfare are all very real - so it is infinitely important to understand how hackers think and act, and how you can fight back.
In this course, which is the first part of the Unlocking Information Security program, you will learn the basic terminology and concepts in the field of information security. You will explore different types of vulnerabilities through famous examples of design flaws, implementation bugs and social engineering.
You will then move on to discover the art of cryptography, from ancient times to the modern era, and learn about famous ciphers, how they can be cracked, and what can be done to thwart such attacks. Next, you will learn about an important aspect of cryptography that involves no secrets at all: hash functions. You will understand what they are, how they can be used, and how they can be attacked.
Finally, you will combine everything you've learned and take a critical view of different authentication schemes: passwords, challenge-response systems and biometrics.
