Kubernetes Misconfiguration: Insufficient Cloud Log Size

Abstract
O tamanho máximo dos arquivos de log de auditoria é muito pequeno.
Explanation
O servidor da API Kubernetes automaticamente faz a rotação dos arquivos de log. Para facilitar a análise pós-incidente e a detecção de ameaças, bem como para atender aos requisitos de conformidade, você deve reter uma quantidade suficiente de dados de log. O sinalizador --audit-log-maxsize define o tamanho máximo em megabytes (MB) do arquivo de log de auditoria antes da rotação ser realizada automaticamente. Ou esse sinalizador não está presente no comando para iniciar um servidor da API Kubernetes ou o tamanho máximo do arquivo de log de auditoria está definido para menos de 100 MB.

Exemplo 1: O comando a seguir inicia um servidor da API Kubernetes e define o sinalizador --audit-log-maxsize para 2 (megabytes), o que é insuficiente.
