Navigating The Mythos-Haunted World Of Platform Security

Vol 337 · Issue 2 · 2026-04-08

The preview release of Claude Mythos presents a massive challenge for IT security experts, as well as an opportunity (at least for the organizations that can afford it). Mythos represents a new category of frontier model that can not only identify complex memory safety issues and logic flaws hidden in legacy code but also exploit them in increasingly sophisticated ways.

MCP Security: Logging And Runtime Security Measures

Vol 337 · Issue 2 · 2026-04-08

Model Context Protocol (MCP) servers often execute code or commands as instructed by an AI agent, exposing them to various risks. To help mitigate these risks, you should implement strict runtime security measures to contain what the server can do and to sanitize what it processes.

Our Journey To AI-Centricity, Part 2: Crafting A Strategy That Scales

Vol 337 · Issue 1 · 2026-03-31

In the first part of this series, we discussed the messy and challenging work of fixing our foundation - standardizing on Red Hat OpenShift and cleaning up years of fragmented data. With that foundation in place, we faced a new challenge: how to integrate AI into how Red Hatters work without creating new internal barriers or security risks.

AI Security: Identity And Access Control

Vol 336 · Issue 4 · 2026-03-27

In our first 3 articles, we framed AI security as protecting the system, not just the model, across confidentiality, integrity, and availability, and we showed why the traditional secure development lifecycle (SDLC) discipline still applies to modern AI deployments.

Beyond The Move: Introducing The Virtualization Migration Assessment Expanded

Vol 336 · Issue 3 · 2026-03-20

For a long time, organizations treated their infrastructure's virtualization layer as steady and predictable. You built on it and you trusted it. Lately, that stability has been disrupted by complex shifts, including rising licensing costs and the urgent requirement to get ready for AI by adding more compute, storage, and other hardware resources. The infrastructure that used to feel settled now feels like it's at a crossroads.

Planning The Design Of Your Production-Grade Rag System

Vol 336 · Issue 1 · 2026-03-06

In our previous article Context as architecture: A practical look at retrieval-augmented generation, we treated retrieval-augmented generation (RAG) as an architectural idea. We explored why retrieval exists, how it changes the system around a language model, and where its boundaries lie. That framing is necessary, but incomplete.

Why The Future Of AI Depends On A Portable, Open PyTorch Ecosystem

Vol 336 · Issue 1 · 2026-03-05

In the debate between open source and proprietary technology, open source wins - especially in the AI arena. However, as the generative AI era continues, enterprises face a new version of an old challenge. While the industry is moving at breakneck speed, much of the underlying infrastructure remains fragmented or locked behind proprietary gates.

Open Data And The AI Resilience Premium

Vol 336 · Issue 1 · 2026-03-04

For many large companies, AI is on every agenda, yet many leaders are still trying to make sense of what to do next. A big reason for this uncertainty is that huge amounts of data are still locked away in separate departments or stuck in systems that don't talk to each other, making it hard to turn that data into real value.
