Is the Internet a safe place? – definitely not, but you don’t necessarily need to be an easy target/low-hanging fruit for hackers. By acquiring some knowledge and learning some rules you can definitely improve your safety level.       The purpose of this course is to teach you how the Internet works and about its intrinsic vulnerabilities. It will show you what you shouldn’t do, and offer a short explanation of why it is dangerous. For example, it will be explained why it is compulsory to use so many different passwords, how to create a good password and why even a very strong password could be not a sufficient measure against criminals.       The course is divided into fifteen, short lectures, and each of them is associated with a few test questions. A database of those questions will be applied for the final assessment (also in form of a test).
