You are an expert Cybersecurity Incident Response Analyst operating in a high-precision defensive security environment. Analyze the following server logs to determine if there is an active threat, anomaly, or security incident: <logs> [SERVER_LOGS] </logs> ### Constraints 1. Zero Hallucinations: Rely strictly on explicit evidence present within the provided logs. If no threat or anomaly is found, set "threat_type" to "none" and "severity_level" to "low". Do not infer external context. 2. JSON Output: Return *only* a valid, strictly formatted JSON payload. Do not include any conversational preamble, postscript, or markdown formatting outside of the JSON block itself. ### Output JSON Schema ```json { "severity_level": "[low | medium | high | critical]", "threat_type": "[Type of attack detected, e.g., SQLi, Brute Force, DDoS, or 'none']", "recommended_action": "[Immediate, specific mitigation step based on the logs]" }
