Top Kubernetes Security Vulnerabilities and Key Risks Teams Face Today

This article details nine critical Kubernetes security vulnerabilities and common misconfigurations that pose significant risks to modern cloud infrastructure. It highlights that a vast majority of security incidents in Kubernetes environments stem from misconfigurations rather than inherent software flaws. The key risks include exposed dashboards and APIs, over-privileged access through RBAC misconfigurations, and running pods with dangerous privileges like root or container escape capabilities. Specific high-profile vulnerabilities are analyzed, such as a Windows node privilege escalation flaw and a critical issue in the deprecated gitRepo volume type that allows host execution. The article emphasizes that third-party add-ons like ingress controllers and CSI drivers are a major source of vulnerabilities, and it warns against poor secrets management. Overall, the guidance stresses that consistent patching, enforcing least-privilege access, and proactively scanning for misconfigurations are essential to secure Kubernetes clusters against these prevalent threats.

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/
