Security and safety are at the core of Facebook. We have entire teams dedicated to building tools that give people even more control over their account and specifically the way they access their information. In fact, many of our most talented engineers are working exclusively on creating a secure environment on Facebook. This October, as part of National Cybersecurity Awareness Month, we are working with others in the community to help educate people about techniques and tools for securing your devices and networks. Additionally, we thought this would be a great opportunity to tell you about some of the systems working behind the scenes to keep you and your data safe.
