Algumas consultas KQL que usamos para o Log Analytics e Resource Graph são simples mas nos fornecem todos os dados que precisamos para uma decisão ou servir de base para hunting.
Alem de algumas consultas "curiosas" que já precisei montar, tambem tenho as que uso em treinamento do Microsoft Defender for Cloud como exemplo de diferentes tipos de consultas.
Decidi juntar todas elas em um repositório no GitHub para ficar fácil a consulta e deixar disponivel para a comunidade.
