Como gerenciar descobertas usando a API Security Command Center

Neste guia, você aprende a criar e atualizar descobertas usando a API Security Command Center.

Antes de começar

Antes de criar e atualizar descobertas, você precisa concluir o seguinte:

Para concluir este guia, você precisa ter o papel Editor de descobertas da Central de segurança (securitycenter.findingsEditor) do Identity and Access Management (IAM) no nível da organização. Para mais informações sobre os papéis do Security Command Center, consulte Controle de acesso.

Para criar descobertas com marcações de segurança, é preciso ter também um papel do IAM que inclua permissões para o tipo de marcação que você quer usar:

  • Gravador de marcação de segurança de recursos (securitycenter.assetSecurityMarksWriter)
  • Como encontrar o gravador de marcações de segurança (securitycenter.findingSecurityMarksWriter)

Para mais informações sobre marcações, consulte Como usar marcações de segurança do Security Command Center.

Como criar uma descoberta

Crie uma descoberta ativa para uma fonte.

gcloud

gcloud scc findings create FINDING_NAME \
    --organization=PARENT_ID \
    --location=LOCATION \
    --source=SOURCE_ID \
    --state=STATE \
    --category=CATEGORY \
    --event-time=EVENT_TIME \
    --resource-name=RESOURCE_NAME

Substitua:

  • FINDING_NAME: o nome da descoberta.
  • PARENT_ID: o ID numérico da organização mãe.
  • LOCATION: se a residência de dados estiver ativada, o local do Security Command Center em que uma descoberta será criada. Se a residência de dados não estiver ativada, use o valor global.
  • SOURCE_ID: o ID numérico da origem da descoberta.
  • STATE: o estado da descoberta. Use ACTIVE se a descoberta precisar de atenção ou INACTIVE se ela tiver sido resolvida.
  • CATEGORY: o grupo de taxonomia ao qual a descoberta pertence. Por exemplo, AUDIT_LOGGING_DISABLED.
  • EVENT_TIME: o horário em que o evento ocorreu, formatado como um carimbo de data/hora RFC 822 ou outro formato de carimbo de data/hora compatível com a CLI gcloud.
  • RESOURCE_NAME: o nome completo do recurso a que a descoberta se aplica.

Para informações sobre como os dados de descobertas são armazenados no Security Command Center, leia Retenção de descobertas.

Como atualizar o estado de uma descoberta

O Security Command Center também fornece uma API para atualizar apenas o estado de uma descoberta. Essa API existe para fornecer uma maneira de atualizar apenas o estado de uma descoberta. É uma API simples que também permite que os principais permissões só possam modificar o estado e nenhum outro aspecto de uma descoberta. Veja no exemplo abaixo como alterar o estado de uma descoberta para inativa.

gcloud

gcloud scc findings update \
    PARENT/PARENT_ID/sources/SOURCE_ID/locations/LOCATION/findings/FINDING_NAME \
    --state=STATE

Substitua:

  • PARENT: o nível da hierarquia de recursos em que a descoberta está localizada. Use organizations, folders ou projects.
  • PARENT_ID: o ID numérico da organização, pasta ou projeto pai ou o ID alfanumérico do projeto pai.
  • SOURCE_ID: o ID numérico da origem da descoberta.
  • LOCATION: se a residência de dados estiver ativada, o local do Security Command Center em que uma descoberta será atualizada. Se a residência de dados não estiver ativada, use o valor global.
  • FINDING_NAME: a descoberta a ser atualizada.
  • STATE: o estado da descoberta. Use ACTIVE se a descoberta precisar de atenção ou INACTIVE se ela tiver sido resolvida.
