Threat Modeling for Modern Supply-Chain Security: How Visibility and Depth Matter

The article argues that effective threat modeling in today’s complex supply chains requires moving beyond surface-level visibility. Rather than just scoping individual tools or vendors, security teams need to model relationships across the full supply-chain ecosystem, including deep tiers. The author recommends using structured approaches (like STRIDE or PASTA) to identify attacker goals, threat actors, and potential attack paths. Crucially, threat modeling should cover build pipelines, policy-as-code, software-component dependencies, and infrastructure — not just the final product. The goal is to shift from reactive security to a proactive, risk-based mindset that anticipates how adversaries might exploit weak links in the chain.

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/
