Trust Beyond Containers: KubeCon 2025’s Shift Toward Identity and Agent Security

The GitGuardian article explains that KubeCon + CloudNativeCon NA 2025 marked a major shift in how the cloud-native community thinks about security. Instead of relying on network boundaries or IP-based controls, the conference emphasized identity-first security. As Kubernetes environments increasingly run AI workloads, securing containers is no longer enough; organizations must secure automated agents, machine identities, and AI-driven services. The article highlights growing adoption of technologies like SPIFFE and SPIRE to create federated trust domains, allowing systems to authenticate based on strong, verifiable identity. According to the author, the future of cloud-native security will depend on consistent identity governance across containers, clusters, and AI agents, redefining trust at every layer of modern infrastructure.

Prompt Engineering Demands Rigorous Evaluation

In the blog post “Prompt Engineering Requires Evaluation” on the Shostack + Associates website, the author argues that treating prompts for large language models (LLMs) merely as creative artefacts is insufficient. Engineering prompts properly demands structured evaluation frameworks — what the AI community calls “evals” — to test which prompt versions work better, with which models, and under which conditions. The post highlights that simply assuming a prompt is “good enough” creates risks when LLMs are integrated into production systems (e.g., for threat modeling). It advocates for measuring prompt performance, variation effects, and tool-chain dependencies (model, context, ancillary materials).  Ultimately the message is: prompt engineering should borrow disciplined practices from software engineering (versioning, testing, benchmarking) rather than relying on informal experimentation.  https://shostack.org/blog/prompt-enignieering-requires-evaluation/

KEVIntel: Real-Time Intelligence on Exploited Vulnerabilities

KEVIntel is a dynamic platform providing up-to-date information on known exploited vulnerabilities (KEVs). It aggregates data from over 50 public sources, including CISA, and enriches each entry with metadata such as EPSS scores, online mentions, scanner inclusion, and exploitation status. The platform aims to serve as an early warning system, offering insights even before official publications. KEVIntel supports various formats like JSON, CSV, and RSS, facilitating integration into security operations. These entries include CVSS scores, exploit status, and links to proof-of-concept code, aiding organizations in prioritizing remediation efforts.   https://kevintel.com/
