From a cybersecurity standpoint, securing AI systems requires defense-in-depth architecture across data, model, and tool execution boundaries. Key security controls include input sanitization to neutralize indirect prompt injection, semantic guardrails that inspect agent trajectories before tool invocation, and cryptographic audit trails for every automated transaction.
In sensitive verticals like healthcare and fintech, organizations must implement tokenization and differential privacy layers to strip Personally Identifiable Information (PII) before prompts reach third-party inference endpoints, ensuring compliance with HIPAA, PCI-DSS, and global data privacy mandates.
