AI News & TrendsOWASP Updates 2026 GenAI Top 10 With 5 Prompt Injection Defenses
Prompt injection is still the most reported security risk in large language model apps, and OWASP's 2026 GenAI Top 10 lists it as the top concern. The article says no single defense stops all prompt injections, so security experts suggest using several layers of protection together. Five main defenses include marking data clearly, setting trust levels for different instructions, limiting what tools the model can use, having humans check risky actions, and splitting planning from execution. OWASP recommends combining these controls and regularly testing systems for new attacks. It appears that following these steps may lower the success of prompt injection but does not remove all risk.
