I dedicate this book to my tireless cheering squad: Lexy, Matteus, Ash, and Vane. Your constant support, encouragement, and celebration of each milestone kept me going. Also, thank you for not judging me for how much ice cream I ate during my editing.

Tanya Janca, also known as SheHacksPurple, is the founder of We Hack Purple, an online learning academy, community, and podcast that revolves around teaching everyone to create secure software. She is also the co-founder of WoSEC: Women of Security, is a project leader for OWASP DevSlop, and is a chapter leader for OWASP Victoria. Tanya has been coding and working in IT for over twenty years, has won numerous awards, and has been everywhere from startups to public service to tech giants (Microsoft, Adobe, and Nokia). She has worn many hats: startup founder, pentester, CISO, AppSec Engineer, and software developer. She is an award-winning public speaker, active blogger and streamer, and has delivered hundreds of talks and trainings on six continents. She values diversity, inclusion, and kindness, which shines through in her countless initiatives.

Dominique Righetto started his career in software development before moving, eight years later, to the security side while continuing to live on the border between the two worlds. Dominique is strongly interested in the offensive and defensive aspects of application security. When he moved into the field of security, his objective was (and always has been) to help development teams integrate security into their projects, using a pragmatic point of view. Dominique has been an active member of the OWASP foundation since 2011, where he contributes to different projects, mainly those concerning the web and mobile domain (his domains specialization). Adept at the open source philosophy, he contributes to various open source projects in his spare time. His homepage is righettod.eu.

Elie Saad is an experienced information security officer working in the banking industry. He leads and contributes to various standardization initiatives at OWASP and regularly publishes articles on the subject. His main drive is to provide guidance for software developers to own and champion security. He has presented several local talks to bring security closer to newcomers and has been a podcast guest on Security Journey, raising the awareness of various AppSec projects. He is an advocate for breaking down the fragmented culture in the AppSec world. In addition, Elie enjoys taking time to appreciate the simpler things in life, a nice breather in the mountains, and a tasteful glass of whiskey (single malt, of course). You can find him on Twitter (.

I would like to thank Jim Minatel, my publisher, for helping me decide that I was ready to write a book, and what type of book to write. Thank you, Adaobi Obi Tulton, my editor, for your endless patience, guidance, and very-helpful-check-ins that kept me on track for the largest project of my professional life. Thank you to Dominique Righetto and Elie Saad, my technical editors. I could never afford to pay you for how hard you both worked to ensure I did not make any grave technical errors. I do not have words to convey my appreciation for your time, expertise, and support. Thank you all for coming on this journey with me.

Why application security? Why should you read this book? Why is security important? Why is it so hard?

If you have picked up this book, you likely already know the answer to this question. You have seen the headlines of companies that have been hacked, data breached, identities stolen, businesses and lives ruined. However, you may not be aware that the number-one reason for data breaches is insecure software, causing between 26% and 40% of leaked and stolen records (Verizon Breach Report, 2019). Yet when we look at the budgets of most companies, the amount allocated toward ensuring their software is secure is usually much, much lower than that.
