This document discusses software supply chain security and vulnerabilities. It references the Equifax data breach in 2017 that was caused by a vulnerability in the Apache Struts software. The document notes that 80-90% of modern applications and operations consist of assembled components, but not all parts are created equal from a security standpoint. It provides statistics showing that 11.1% of Java components downloaded annually have known vulnerabilities and that 80% of organizations analyzed show poor cyber hygiene. The key takeaway is that businesses are ultimately responsible for the security of their data and systems, so emphasizing security for the entire software supply chain is important.
