Secure Coding in JavaScript: Best Practices for 2025

A recent Stack Overflow blog post outlines essential practices for writing secure JavaScript code, emphasizing the importance of preventing cross-site scripting (XSS) attacks. The article provides ten actionable tips, including input validation, output encoding, and the use of Content Security Policy headers. It also highlights the advantages of modern JavaScript frameworks like React, Angular, and Vue.js, which offer built-in security features. The post advocates for separating JavaScript from HTML to reduce XSS risks and stresses the need for a secure software development lifecycle (S-SDLC) to ensure comprehensive security measures throughout the development process.

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/
