소프트웨어 보안은 보안 소프트웨어가 아닙니다. 여기서는 인증, 액세스 제어, 기밀성, 암호화, 권한 관리 등의 항목에 대해 설명합니다.

Authentication Bad Practice: Missing Check against Evaluation Result

Objective-C
Swift

Explanation

서버 신뢰 자격 증명을 생성하기 전에, 서버 신뢰를 평가하는 것은 NSURLConnection 개체, NSURLSession 개체 또는 NSURLDownload 개체 대리자의 책임입니다. 서버 신뢰를 평가하기 위해 SecTrustEvaluate(_:_:) 메서드는 서버의 NSURLProtectionSpace 개체의 serverTrust 메서드로부터 얻은 신뢰를 사용하여 호출되어야 합니다.

SecTrustEvaluate(_:_:) 메서드는 두 개의 다른 값을 반환합니다.

- 반환된 OSStatus 값은 결과 코드를 나타냅니다.
- 두 번째 인수가 가리키는 개체는 평가의 결과 유형을 나타냅니다.

신뢰가 유효하지 않은 경우, cancel(_:)로 인증 챌린지를 취소해야 합니다.

예제 1: 다음 예제에서는 서버 신뢰가 평가되지만 수신된 자격 증명은 이 평가의 결과를 확인하지 않고 사용됩니다.


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