Getting Out Of Walled Gardens By Running Your Own Email - Michael Harrison

In this episode of the Security Repo Podcast, we explore the intersection of observability and security with special guest Josh Lee, a developer advocate at Altinity and expert on Clickhouse and OpenTelemetry. We discuss the evolving definition of observability, how context and tagging enhance both security and observability practices, and how databases like ClickHouse® compare to Snowflake for monitoring applications at scale. Josh also shares insights on DevOps culture as a "foreign language" and how to bridge gaps between developers and operators in adopting modern practices. Josh is a seasoned software developer with over a decade of experience, specializing in a broad range of topics including operations, observability, and cloud-native databases. His passion for technology is matched by his enthusiasm for sharing knowledge through public speaking. Currently, Josh serves as a Developer Advocate for Altinity, where he creates educational content on ClickHouse® and OpenTelemetry.

In this episode of the Security Repo Podcast, we talk with cybersecurity expert Stephanie Honore, about her journey into security, her work with the Freedom of Information Act (FOIA), and her insights on ethical AI and chain of custody in data handling. She shares her experience building software for evidence management and her thoughts on the intersection of security and legal frameworks. We also explore her creative side as a "spycore" musician blending cybersecurity themes with nerdcore music. Stephanie Honore, also known as Scarlett Danger, is a professional programmer, building applications by day, and a volunteer OSINT investigator by night for NGOs that combat human trafficking. She has been a member of WiCyS (Woman of Cybersecurity) since 2016 and attended Hacker On The Hill in Jan 2024.  She began by attending the local hacker meetups and frequently attends cybersecurity conferences such as BSides and Texas Cybersecurity Summit. She recently started joining online chat communities on Discord and IRC where she is getting a lot of exposure to a different side of the security field. Outside of work she likes making nerdcore music about security and intelligence ( a genre she has dubbed spycore) inspired greatly by performers like YTCracker, MC Frontalot, and Yung Innanet.  You can listen to one of my songs here.  https://soundcloud.com/scarlett_danger/hack-the-planet-v2?in=scarlett_danger/sets/internet-feels https://www.linkedin.com/in/smhonore/ https://smhonore.deno.dev/ https://www.wicys.org/ https://www.muckrock.com/news/archives/2024/aug/26/with-a-little-help-from-the-national-archives-nsa-finally-releases-grace-hopper-lecture-watch-it-here/

In this episode of the Security Repo Podcast, we explore the fascinating and complex world of non-human identities (NHIs) with Jody Hunt from CyberArk. We discuss the challenges of authenticating machine workloads, delve into the "secret zero" problem, and consider how frameworks like SPIFFE are shaping the future of secure machine identity. Plus, Jody shares his journey through a tech acquisition and the enduring importance of thinking like an attacker in cybersecurity. Jody has held diverse roles in software development, sales, and marketing. He has been an enthusiastic promoter of DevOps principles since 2010. He became aware of the growing security gap introduced by automation which led him to join Conjur in 2017. Four months later, CyberArk acquired Conjur to extend secrets management and machine identity solutions to DevOps, Cloud and Kubernetes workloads. https://www.linkedin.com/in/jodyhuntatx/ https://spiffe.io/book/ https://blog.gitguardian.com/protect-secrets-with-cyberark-and-gitguardian-integration/
