Identity Security for Software Development: Building with Identity, Secrets, and Credentials (eng)

Maintaining secrets, credentials, and machine identities in secure ways is an important, though often overlooked, aspect of secure software development. DevOps security often addresses vulnerabilities, but it neglects broader discussions like authentication, authorization, and access control, potentially leaving the door open for breaches. That's where an identity security strategy integrated in your code, infrastructure, and environments from day one can help.

In this practical book, authors John Walsh, Uzi Ailon, and Matt Barker provide conceptual frameworks, technology overviews, and useful code snippets to bridge the gap between development, IT, and security to integrate robust identity security across apps, CI/CD pipelines, Kubernetes and cloud native, hybrid and multicloud, process automation, IoT, and more. You'll learn:

• What developers need to know about managing secrets and identity to build safer apps
• What machine identities, secrets, and credentials are—and how to secure them
• How to secure the software supply chain to build safer apps
• How identity security fits into modern software development practices

Matt was co-founder & CEO of Jetstack, a Kubernetes company he bootstrapped in 2015 before being acquired by Venafi in 2020. Venafi was subsequently acquired by private equity company Thoma Bravo, and then the cybersecurity company CyberArk.

Jetstack is best known for its open source project 'cert-manager', which is downloaded millions of times a day to secure cloud native infrastructure. Cert-manager was donated to the CNCF in 2020, and graduated in 2024.

Matt has played a number of product and leadership roles since being acquired, and now leads workload identity at CyberArk (think SPIFFE!) In January 2021, Matt was awarded as a top 100 Open Source Influencer by OpenUK. He also acts as Entrepreneur as Residence for Open UK, and has an advisory role with the AI engineering firm Helix.
