As in many cutting-edge companies, the environment at Netflix is constantly changing. New applications are deployed everyday, code is pushed every hour, and systems are spun up and down at will to support changing demand patterns of online video streaming. This, combined with Netflix’s 100 percent cloud model, provides significant challenges in understanding its assets, the risk they pose, and the vulnerabilities they expose.
In order to help address these issues, Netflix developed and released an open source tool call Scumblr in 2014. Andy Hoernecke and Scott Behrens introduce Scumblr, which has been successful in tackling a broad range of security challenges.
Scumblr was initially focused on the outside—finding interesting intelligence from the Internet and bringing it to Netflix’s attention. Internally, however, Andy and Scott’s team found new and innovative ways to use the Scumblr platform to make an appsec engineer’s life a little bit easier. Through a series of small tweaks—and larger architectural changes—Scumblr has become a versatile tool that allows Netflix to track a wide range of information, including changes to endpoints on Netflix.com, risk profiles for each application in its environment, and the status of vulnerabilities across a thousands of applications. The team has made changes to Scumblr to make it faster, more flexible, and more powerful, and they are ready to share these changes with the open source community.
You’ll gain an understanding of how the Netflix team designed a tool that has been successful in tackling a broad range of security challenges. Andy and Scott share the latest uses for the tools, including details on how Netflix is using Scumblr for vulnerability management, application risk tracking, and other uses. Andy and Scott conclude with a discussion of how you can replicate Netflix’s success with Scumblr using plugins that integrate with Arachni, AppSpider, and GitHub and explain just how easy it is to create new integrations that open up new opportunities for automation, data collection, and analysis.
