The document discusses lessons learned from the Building Security in Maturity Model (BSIMM) based on data from over 100 software security initiatives. It provides the following key points:
1. Software security initiatives progress at different rates based on an organization's risk drivers, budget, and priorities. Mature initiatives are typically led by senior executives and have cross-functional support.
2. While security tools are important, mature organizations know that experts are also needed to properly interpret results and prioritize issues.
3. No initiative can succeed without leadership, and mature initiatives establish governance, policy, and standards set by a dedicated security group.
