Introducing DeepViolet

This blog post announces DeepViolet, an open-source TLS and SSL analysis library that has been integrated into the ZAP HTTPS Info add-on to deliver risk assessments alongside connection details. DeepViolet provides a modular API that performs TLS handshake analysis, certificate chain validation, revocation checks, security header inspection, and DNS lookups, returning structured results with a numeric risk score and letter grade. The post walks through a sample scan showing how findings are categorized into protocols and connections, revocation and transparency, security headers, DNS security, certificate details, and cipher suites. The library is structured as a core API available on Maven Central, a standalone Java Swing desktop application for ad-hoc investigations, and a command-line interface for scripting. Planned features include scan persistence, customizable risk scoring with YAML-based rules, user-editable cipher suite evaluations, certificate transparency analysis, and AI-augmented reporting with support for both cloud-based and local large language models. The HTTPS Info add-on currently requires Java 21, while ZAP itself needs Java 17.

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/
