The New AI Security Frontier: Inside the Hidden Attack Surface

Traditional security frameworks built around protecting network perimeters are obsolete in the AI era—the real attack surface has shifted to the interaction layer where prompts meet language models. LLMs process trusted instructions and untrusted user input as indistinguishable token streams, making semantic threats like prompt injection fundamentally different from traditional exploits. This architectural vulnerability makes real-time prompt filtering not just recommended but essential for any serious AI security strategy.
