This chapter has covered the origin and benefits of bug bounty programs, the background knowledge you need coming in, an overview of some of the tools we'll use in our engagements, how to get the most out of this book (practice on allowed sites), and finally, the moral and legal peril you risk by not abiding by a target site's rules of engagement or code of conduct.
In the next chapter, we'll cover different types of bug bounty programs, the key factors differentiating them, how you can evaluate where you should participate, as well as what applications make good targets, where you should focus your research, and finally, how you can use a program's rules of engagement to minimize your legal liability as a security researcher.
