Mitigating attacks against AI-enabled Apps, Replacing the CIA triad, Enterprise News - David Brauchler - ESW #429
Enterprise Security Weekly (Audio)
How will AI change vulnerability discovery and remediation?
Hosts summarize Schneier, Evron, and Adkins on AI accelerating vulnerability discovery, vuln‑ops, and potential self‑healing networks.
David Brauchler says AI red teaming has proven that eliminating prompt injection is a lost cause. And many developers inadvertently introduce serious threat vectors into their applications – risks they must later eliminate before they become ingrained across application stacks.
NCC Group's AI security team has surveyed dozens of AI applications, exploited their most common risks, and discovered a set of practical architectural patterns and input validation strategies that completely mitigate natural language injection attacks. David's talk aimed at helping security pros and developers understand how to design/test complex agentic systems and how to model trust flows in agentic environments. He also provided information about what architectural decisions can mitigate prompt injection and other model manipulation risks, even when AI systems are exposed to untrusted sources of data.

An op-ed on CSO Online made us think - should we consider the CIA triad 'dead' and replace it? We discuss the value and longevity of security frameworks, as well as the author's proposed replacement.
