What is Prompt Injection Defense in Applied AI?
A layered set of controls that reduce the chance of a successful prompt-injection attack. Defenses include trust separation between system and user content, input sanitization, output filtering, isolated tool execution, and detection rules tuned to known injection patterns. No single control is sufficient on its own.
Why Prompt Injection Defense Matters for Your AI or Cybersecurity Career
Every enterprise shipping LLM features needs prompt-injection defense in the design, not as an afterthought. The role title varies by company, but the work is one of the most in-demand AI security specializations on the market.
