The uptime questions every engineering leader should ask this week

In this interview with Help Net Security, Mattias Geniar, CTO at Oh Dear, explains why most outages start quietly, as creeping latency or a slow rise in errors. He argues teams alert on the wrong things: absolute numbers instead of changes, isolated en… Continue reading The uptime questions every engineering leader should ask this week

Where IT meets OT and railway cybersecurity gets harder

In this interview with Help Net Security, Jorge Aldegunde, Global Head of Railway Services at DNV, talks through what happens when old operational technology meets newer IT in monorail systems. He explains why open networks widened the attack surface, … Continue reading Where IT meets OT and railway cybersecurity gets harder

Praxen: Open-source AI agent behavior verification

Praxen is an open-source tool with a simple job: it checks whether an AI agent does what it claims to do. The tool takes an agent’s declared policy, looks at how the agent operates, and points out every spot where the two drift apart. It is the r… Continue reading Praxen: Open-source AI agent behavior verification

A $1,400 experiment in AI security auditing outperformed OpenAI’s Codex Security

A research team has built a system that teaches AI agents to hunt for software bugs by writing the audit method down as plain text. The system, called EVOHUNT, keeps the underlying AI model fixed and improves only an external “playbook” tha… Continue reading A $1,400 experiment in AI security auditing outperformed OpenAI’s Codex Security

Who pays when you gate cyber-capable AI models?

In this interview with Help Net Security, Jaya Baloo, COO & CISO at Aisle, examines the debate over restricting access to cyber-capable AI models. She lays out the strongest argument for gating these tools, then explains where it breaks down for s… Continue reading Who pays when you gate cyber-capable AI models?

Agent Beacon: Open-source telemetry layer for AI agents

AI coding agents such as Claude Code, Codex CLI, Cursor, and Claude Cowork run on developer laptops, CI jobs, cloud environments, where they edit files, run commands, and call outside tools. Beacon, an open-source project from Asymptote Labs, configure… Continue reading Agent Beacon: Open-source telemetry layer for AI agents

Encrypted DNS still tells an eavesdropper where to look

Encrypted DNS runs across much of the Internet. DNS over TLS, HTTPS, and QUIC keep the contents of a query away from anyone watching a network link. The encryption covers the message inside each packet. The packet still carries plaintext headers, and t… Continue reading Encrypted DNS still tells an eavesdropper where to look

Your browser tab could become encrypted storage for someone else’s files

Decentralized storage networks already hand pieces of people’s data to strangers’ machines. The lasting question across these networks is whether the machine holding the data can read it. A research paper by Gregory Magarshak, a professor a… Continue reading Your browser tab could become encrypted storage for someone else’s files
