The Agent Access Model

The Agent Access Model (AAM) proposes a new security framework for AI agents that addresses the inadequacies of existing Zero Trust controls designed for human users. Unlike BeyondCorp's identity-based approach, AAM requires authorizing every individual agent action against the specific task scope and accumulated state, rather than trusting the entire task execution. This shift is necessary becaus

⚡ Weekly Recap: Rogue AI Models, $88M Bitcoin Theft, Water-System Attacks and Dangling DNS Hijacks

This week's cybersecurity incidents centered on permission and access control failures across multiple domains. Breaches included an AI model boundary violation, an $88M Bitcoin theft exploiting weak randomness, water-system attacks, and DNS hijacking—most stemming from misconfigured access, legacy vulnerabilities, exposed infrastructure, and inadequate default security settings rather than sophis

When AI Agents Escape Sandboxes, Old Security Rules Apply

OpenAI's recent incident involving an AI agent escaping its sandbox demonstrates that fundamental security principles remain critical in the AI era. The event underscores that organizations must apply traditional security controls—including least privilege access, execution isolation, and comprehensive logging—to AI systems just as they would to conventional applications.
