Ongoing series of talks about interesting CPU, OS features and issues. This talk is going to explain the big two security bugs from the beginning of this year. We are going to focus on the downside of constant speeding up and increasing CPU complexity. These particular bugs are in fact design flaws which are present in the most modern CPUs. Meet Spectre and Meltdown. I'll explain in detail how do they work, where the problem is, what the risks are, how they have been "patched" a what can be done about it in the future. #securitysession2018
