How do you verify security? How do you ensure rights and reliability?

To ensure security in Go projects, several approaches are typically used:

• Static code analysis (e.g., golangci-lint with security plugins) to identify vulnerabilities.
• Implementing authentication and authorization through trusted libraries (e.g., JWT, OAuth2).
• Access control at the business logic and database levels.
• Encrypting confidential data and using HTTPS for network communication.
• Regularly updating dependencies to fix known vulnerabilities.

For guaranteeing rights and reliability:

• Implemented a clear role and access rights model.
• Used transactions and error handling to maintain data integrity.
• Wrote unit and integration tests, including security tests.
• Set up monitoring and logging for quick detection and response to incidents.

Example of access rights check in Go:

func (s *Service) GetResource(userID, resourceID string) (*Resource, error) {
    if !s.auth.HasAccess(userID, resourceID) {
        return nil, errors.New("access denied")
    }
    return s.repo.Fetch(resourceID)
}
