The practice of protecting AI systems and workflows from misuse, manipulation, or unauthorized access.
Security in prompt engineering focuses on protecting the system, its inputs, and its outputs from abuse. That includes malicious prompts, prompt injection, data leakage, unsafe tool use, and unauthorized access to sensitive information.
As AI systems become more connected to tools and internal data, security becomes more important. A prompt is no longer just text when it can influence application behavior, API calls, or business decisions.
Secure prompt systems combine prompt design with software controls such as access restrictions, validation, monitoring, and safe execution boundaries.
