OWASP LLM10 covers floods, denial of wallet and model extraction. A defensive plan: the fields to log, the alerts to set and the limits to enforce.
OWASP LLM10 covers denial of service, runaway cost and model theft. Rate limits, quotas, timeouts and budgets work. A hidden endpoint does not.
OWASP LLM08 covers leaks, poisoning and inversion in RAG systems. A hiring screen scenario from OWASP shows the risk and the controls that reduce it.
OWASP LLM08 covers RAG risks like leakage, poisoning and inversion. Which controls address them, and why prompt instructions alone do not. Defensive guide.

OWASP says a system prompt is not a secret or a security control. Here is how LLM07 maps to NIST AI RMF practices and what evidence to keep for audits.
OWASP LLM06 excessive agency has three root causes. How each lines up with least privilege, human oversight and AI risk frameworks, plus a checklist.
OWASP LLM05 is about trusting model output downstream. Log every handoff from model to code and alert on validation failures and odd patterns.
