The argument centers on reachability. A finding counts only when someone walks the path to impact on a working build. He shows how a chain of small design choices led to account takeover in a popular open-source project, then covers how to test a vendor’s claims, … More → The post Reachability makes AI threat modeling worth the trust appeared first on Help Net Security.

The rise of machine identities and agentic AI: Securing trust in the next era of digital autonomy

In the latest episode of Identity Insider, I sat down with Chris Hughes, a cybersecurity expert who’s involved in OWASP’s work on non-human and machine identity security. Unsurprisingly, our discussion centered on the rapidly changing cybersecurity landscape, driven by the rise of artificial intelligence (AI), particularly agentic AI, which is giving systems unprecedented autonomy within the enterprise. You can watch our full discussion here: The conversation reinforced something I’ve been thinking about for a while: … More → The post The rise of machine identities and agentic AI: Securing trust in the next era of digital autonomy appeared first on Help Net Security.
