In this episode of Google's SRE Production Podcast, host Steve McGhee and Jordan Greenberg welcome Jessica Theodat to discuss the intersection of security and reliability in site reliability engineering. Jessica, a security-focused reliability engineer, explains how security and reliability can sometimes pull in opposite directions, with security aiming to resist and control while reliability focuses on ensuring availability. The conversation explores the importance of finding the right balance between the two, integrating security considerations early in the design phase, and developing shared tooling to foster collaboration between security and reliability teams. The discussion also covers incident response, highlighting the need for compartmentalizing information in security incidents due to potential active adversaries, and concludes with advice on how organizations can prioritize and align their security and reliability efforts to achieve business goals and maintain user trust, especially in the context of AI.
