The Agentic AI Security Scoping Matrix: A framework for securing autonomous AI systems

As generative AI became mainstream, Amazon Web Services (AWS) launched the Generative AI Security Scoping Matrix to help organizations understand and address the unique security challenges of foundation model (FM)-based applications. This framework has been adopted not only by AWS customers across the globe, but also widely referenced by organizations such as OWASP, CoSAI, and […]

New Amazon Threat Intelligence findings: Nation-state actors bridging cyber and kinetic warfare

The new threat landscape The line between cyber warfare and traditional kinetic operations is rapidly blurring. Recent investigations by Amazon threat intelligence teams have uncovered a new trend that they’re calling cyber-enabled kinetic targeting in which nation-state threat actors systematically use cyber operations to enable and enhance physical operations. Traditional cybersecurity frameworks often treat digital […]

Build secure network architectures for generative AI applications using AWS services

As generative AI becomes foundational across industries—powering everything from conversational agents to real-time media synthesis—it simultaneously creates new opportunities for bad actors to exploit. The complex architectures behind generative AI applications expose a large surface area including public-facing APIs, inference services, custom web applications, and integrations with cloud infrastructure. These systems are not immune to […]
