In this episode:

• What would it take to build your entire security program on open source software, tools, and intelligence?
• Is it possible/feasible/practical to run a security program entirely based upon free and open source software, open source tools, and open source intelligence?
• Is it true that the more open source you use the more people you need?
• Do commercial software systems, tools, and intelligence have value above what can be found in open source?
