AWS CloudFormation Misconfiguration: Missing CloudTrail Log Validation
Abstract
O modelo define uma trilha sem validação de arquivo de log.
Explanation
Por padrão, a validação do arquivo de log do CloudTrail está desabilitada, o que evita que os investigadores afirmem que não houve violação externa dos arquivos de log do CloudTrail.
Um resultado direto disso é que um invasor com os privilégios necessários pode realizar alterações prejudiciais na configuração e cobrir seus rastros, modificando os logs do CloudTrail.
Exemplo 1: A seguir está um exemplo de uma trilha com a validação do arquivo de log desativada definindo
