Folha de Dicas de Listagem de Ativos em Nuvem do Cloudlist

Visão Geral

Cloudlist é uma ferramenta multi-cloud desenvolvida pelo Project Discovery para listar ativos de diversos provedores de nuvem. Foi projetada para ajudar equipes de segurança a aprimorar seus esforços de Gerenciamento de Superfície de Ataque, descobrindo e monitorando ativos em nuvem em múltiplos provedores, incluindo AWS, Azure, GCP, DigitalOcean, Linode, Alibaba Cloud, entre outros.

O que diferencia o Cloudlist de ferramentas específicas de provedor é sua interface unificada para consultar múltiplos provedores de nuvem simultaneamente. Isso simplifica significativamente o processo de manutenção de um inventário de ativos em nuvem, especialmente para organizações que utilizam múltiplos provedores de nuvem. O Cloudlist fornece uma saída consistente independentemente do provedor, facilitando a integração em fluxos de trabalho de segurança e pipelines de automação.

O Cloudlist é primariamente destinado a equipes blue teams para manter visibilidade sobre sua infraestrutura em nuvem, mas também é valioso para equipes red teams e penetration testers que precisam compreender a superfície de ataque de uma organização. Ao fornecer uma visão abrangente dos ativos em nuvem, o Cloudlist ajuda profissionais de segurança a identificar potenciais riscos de segurança, como serviços expostos, recursos mal configurados ou implantações não autorizadas.

Troubleshooting

Common Issues

1. Authentication Issues

   # Verify provider configuration
   cloudlist -list
   
   # Update provider credentials
   cloudlist -remove aws
   cloudlist -add aws -aws-access-key NEW_ACCESS_KEY -aws-secret-key NEW_SECRET_KEY

2. Rate Limiting

   # Reduce concurrency
   cloudlist -concurrency 5
   
   # Add delay between requests
   cloudlist -delay 2

3. Permission Issues

   # Check if credentials have sufficient permissions
   # For AWS, ensure the IAM user/role has the necessary read permissions
   # For Azure, ensure the service principal has the Reader role
   # For GCP, ensure the service account has the necessary viewer roles

4. No Results

   # Check if provider is configured correctly
   cloudlist -list
   
   # Try a different provider
   cloudlist -provider azure
   
   # Check if resources exist in the account

Debugging

# Enable verbose mode
cloudlist -v

# Show debug information
cloudlist -debug

# Check provider configuration
cloudlist -list
