Building software today involves more assembly than actual coding. Much of our code is in fact pulled in open source packages, and the applications heavily rely on surrounding third party binaries. These third parties make us more productive - but they also introduce an enormous risk. Each third party component is a potential source of vulnerabilities or malicious code, each third party service a potential door into our system. This talk contains more information about this risk, create a framework for digesting and tackling it, and lists a myriad of tools that can help.
