Cybersecurity is broken. Year after year, attackers remain unchallenged and undeterred, while engineering teams feel pressure to design, build, and operate "secure" systems. Failure can't be prevented, mental models of systems are incomplete, and our digital world constantly evolves. How can we verify that our systems behave the way we expect? What can we do to improve our systems' resilience?In this comprehensive guide, authors Kelly Shortridge and Aaron Rinehart help you navigate the challenges of sustaining resilience in complex software systems by using the principles and practices of security chaos engineering. By preparing for adverse events, you can ensure they don't disrupt your ability to innovate, move quickly, and achieve your engineering and business goals.Learn how to design a modern security programMake informed decisions at each phase of software delivery to nurture resilience and adaptive capacityUnderstand the complex systems dynamics upon which resilience outcomes dependNavigate technical and organizational trade-offs that distort decision making in systemsExplore chaos experimentation to verify critical assumptions about software quality and securityLearn how major enterprises leverage security chaos engineeringAbout the AuthorKelly Shortridge is a senior principal engineer at Fastly in the office of the CTO. Shortridge is best known for their work on resilience in complex software systems, the application of behavioral economics to cybersecurity, and bringing security out of the dark ages. Shortridge has been a successful enterprise product leader as well as a startup founder (with an exit to CrowdStrike) and investment banker. Shortridge frequently advises Fortune 500s, investors, startups, and federal agencies and has spoken at major technology conferences internationally, including Black Hat USA, O’Reilly's Velocity Conference, and SREcon. Shortridge’s research has been featured in ACM, IEEE, and USENIX, spanning behavioral science in cybersecurity, deception strategies, and the ROI of software resilience. They also serve on ACM Queue’s magazine editorial board.
