Segurança de software não é o mesmo que software de segurança. Aqui, estamos interessados em tópicos como autenticação, controle de acesso, confidencialidade, criptografia e gestão de privilégios.

Authentication Bad Practice: Missing Check against Evaluation Result

Explanation
Antes da criação de uma credencial de confiança de servidor, é responsabilidade do representante de um objeto NSURLConnection, de um objeto NSURLSession ou de um objeto NSURLDownload avaliar a relação de confiança do servidor. A fim de avaliar a relação de confiança do servidor, o método SecTrustEvaluate(_:_:) deve ser chamado com a confiança obtida do método serverTrust do objeto NSURLProtectionSpace do servidor.

O método SecTrustEvaluate(_:_:) retorna dois valores diferentes:

- O valor OSStatus retornado representa o código de resultado.
- O objeto apontado pelo segundo argumento representa o tipo de resultado da avaliação.

Se a confiança for inválida, o desafio de autenticação deverá ser cancelado com cancel(_:).

Exemplo 1: No exemplo a seguir, a relação de confiança do servidor é avaliada, mas as credenciais recebidas são usadas sem verificar o resultado dessa avaliação:


SecTrustRef trust = [[challenge protectionSpace] serverTrust];
SecTrustResultType result = kSecTrustResultInvalid;
OSStatus status = SecTrustEvaluate(trust, &result);
completionHandler(NSURLSessionAuthChallengeUseCredential, [challenge proposedCredential]);
