Verificação de Dependências

Identifique vulnerabilidades em dependências e bibliotecas de terceiros.

Quando Usar Esta Habilidade

Use esta habilidade quando:

• Gerenciar dependências de terceiros
• Implementar análise de composição de software
• Atender a requisitos de conformidade
• Proteger a cadeia de suprimentos de software
• Automatizar a detecção de vulnerabilidades

Pré-requisitos

• Arquivos de manifesto de pacotes (package.json, requirements.txt, etc.)
• Acesso ao pipeline de CI/CD
• Ferramenta de verificação de dependências

Snyk

Uso da CLI

# Install
npm install -g snyk

# Authenticate
snyk auth

# Test project
snyk test

# Monitor project (track over time)
snyk monitor

# Test specific manifest
snyk test --file=package.json
snyk test --file=requirements.txt

# Output formats
snyk test --json > snyk-results.json
snyk test --sarif > snyk-results.sarif

# Fix vulnerabilities
snyk fix

# Ignore vulnerability
snyk ignore --id=SNYK-JS-LODASH-567746 --expiry=2024-12-31 --reason="No exploit path"
