ที่วางไว้เพื่อควบคุมให้ระบบ AI ทำงานอยู่ในขอบเขตที่ปลอดภัย โดยครอบคลุมตั้งแต่ข้อมูลนำเข้า ตัวโมเดล LLM ไปจนถึงผลลัพธ์ที่ส่งให้ผู้ใช้งาน เป้าหมายสำคัญคือการป้องกันการนำ AI ไปใช้ในทางที่ผิด

ช่วยป้องกันภัยคุกคามหลักอย่าง Prompt Injection และ Jailbreaks ที่พยายามหลอกให้ AI ข้ามข้อจำกัดความปลอดภัย นอกจากนี้ยังช่วยป้องกัน Data Leakage หรือการเผลอเปิดเผยข้อมูลส่วนบุคคล PII ข้อมูลทางการแพทย์

มีความสำคัญมากสำหรับระบบที่อนุญาตให้ AI รันคำสั่ง shell command ได้ เช่น AI coding assistant หรือ AI agent ที่มีการเรียกใช้เครื่องมือ กลไกนี้จะช่วยจำกัดสิทธิ์การทำงานผ่าน Command Whitelisting การแยกส่วนระบบไฟล์ และการจำกัดทรัพยากรอย่าง CPU หรือ Memory มาตรการเหล่านี้ช่วยป้องกันไม่ให้ AI รันคำสั่งอันตราย เช่น การลบไฟล์ระบบหรือการส่งข้อมูลออกไปภายนอก",{"q":8631,"a":8632},"ทำไมการใช้
