Tracking Protection Using Firefox.

We often gloss over exactly why personal data is worth protecting. If you are not paying for the product, you are the product. As a solution are you using private browsing or incognito mode? I am afraid it’s not enough to stop the data leaks. This session is for everyone who wants to protect the data and privacy by doing more. It’s us who can take action to change our habits and start protecting our privacy and our data. We will talk about possible data threats and the ways to use your browser in a more secure way to protect your privacy. We also demo how to change Firefox’s configuration to help stop data leaks from your browser and finding an alternative to the most widely used search engines

Michael Sudakovitch

Uber

I joined Uber Engineering Security as a Cloud Security engineer shortly after the infamous 2016 data breach, which partially resulted in poor cloud asset management and lack of real-time incident response. At the time, the challenge grew bigger as we continued to expand into additional cloud providers, namely GCP and Azure. Along with my peers, I was tasked with “hardening the cloud environment”, and the system I describe in this talk (internally called CLogS, standing for “Cloud Logging System”) was one of the outcomes and my main contributions. It employs Cloud-native services and uses wide-scale containerized deployment. The system is now widely adopted throughout the company and has proven itself numerously in both table-top exercises and real attacks and anomalies. This would be the first talk outside of Uber describing this system.
