Abstract
프로그램은 전송 또는 메시지 보안을 정의하지 못합니다.
Explanation
전송 또는 메시지 보안 없이 메시지를 전송하는 프로그램은 메시지의 무결성 또는 기밀성을 보장할 수 없습니다. WCF 보안 바인딩이 None으로 설정되면 전송 및 메시지 보안 모두 비활성화됩니다.

예제 1: 다음 코드는 가상 Widget 서비스에 대한 WCF Basic HTTP Binding의 보안 모드를 None으로 설정합니다.


BasicHttpBinding binding = new BasicHttpBinding();
binding.Security.Mode = BasicHttpSecurityMode.None;

ServiceHost serviceHost = new ServiceHost(typeof(Widget), baseAddress);
serviceHost.AddServiceEndpoint(typeof(Widget), binding, new URI("ExposureAddress"));

Abstract
시스템 리소스 사용에 제한을 두지 않으면 리소스가 고갈되어 궁극적으로 Denial of Service가 발생할 수 있습니다.
Explanation
WCF(Windows Communication Foundation)는 서비스 요청을 제한하는 기능을 제공합니다. 너무 많은 클라이언트 요청을 허용하면 시스템에 과부하가 걸리고 리소스가 고갈될 수 있습니다. 반면에 서비스에 대한 요청을 소수만 허용하면 합법적인 사용자가 서비스를 사용하지 못하게 될 수 있습니다. 적절한 양의 리소스를 허용하도록 각 서비스를 개별적으로 조정하고 구성해야 합니다.

Abstract
응용 프로그램은 전송 모드 전송 보안을 사용하는 WCF 끝점을 사용합니다. 전송 모드는 최소한의 보안 옵션이며 피해야 합니다.
Explanation
전송 보안은 기밀성, 무결성 및 인증이 HTTPS와 같은 전송 레이어 메커니즘에 의해 제공되는 것으로 지정합니다. HTTPS와 같은 전송을 사용할 때 이 모드는 성능에서 효율적인 이점이 있고 인터넷을 통한 보급으로 인해 잘 알려져 있습니다. 단점은 이런 종류의 보안이 통신 경로의 각 홉에서 개별적으로 적용되어 통신이 "MITM(Man-In-The-Middle)" 공격에 취약해진다는 점입니다. WCF는 두 가지 기타 전송 보안 모드를 제공하는데, 두 가지 즉, 메시지 및 메시지 자격 증명이 있는 전송이 모두 선호됩니다. 메시지 보안은 WS-Security 사양을 사용하여 기밀성, 무결성 및 인증을 메시지 수준으로 보장합니다. 그러면 전송 메서드의 엔드투엔드(end-to-end) 보안 및 유연성이 제공됩니다. 그러나 성능이 감소됩니다.

마지막 방법인 메시지 자격 증명을 사용한 전송은 전송과 메서드의 혼종입니다. 메시지 보안은 클라이언트를 인증하는 데 사용되며 전송 보안은 서버를 인증하고 기밀성과 무결성을 제공하는 데 사용됩니다. 이 방법은 거의 기본 전송 보안만큼 효율적입니다.

Abstract
이 서비스는 권한 부여 제어를 사용하지 않습니다.
Explanation
클라이언트가 특정 WCF 서비스를 호출할 때, WCF는 호출자가 서버에서 service 메서드를 실행하는 권한을 가지는지 확인하는 다양한 권한 부여 스키마를 제공합니다. 권한 부여 제어가 WCF 서비스에 활성화되어 있지 않은 경우, 인증된 사용자가 권한 상승을 얻을 수 있습니다.

예제 1: 다음 코드는 WCF가 서비스 실행 시 클라이언트의 권한 부여 수준을 검사하지 않도록 지시합니다.


ServiceHost myServiceHost = new ServiceHost(typeof(Calculator), baseUri);
ServiceAuthorizationBehavior myServiceBehavior =
myServiceHost.Description.Behaviors.Find<ServiceAuthorizationBehavior>();
myServiceBehavior.PrincipalPermissionMode =
PrincipalPermissionMode.None;

Abstract
이 프로그램은 인증서 해지 확인을 활성화하지 못하므로 손상된 것으로 알려지거나 의심되는 인증서를 수락하게 됩니다.
Explanation
CRL(인증서 해지 목록)은 인증 기관에서 만들고 서명한 PKI(공개 키 인프라) 배포의 선택적 구성 요소이며 발급 후 나중에 해지한 인증서 목록을 포함합니다. 예를 들어 발급된 인증서가 손상된 것으로 알려지거나 의심되는 경우 인증 기관 관리자는 인증서를 취소할 수 있습니다.

예제 1: 다음 예제에서 서비스 동작은 인증서 인증 시 해지 확인을 수행하지 않도록 구성됩니다.

Abstract
이 프로그램은 약한 클래스 참조를 사용합니다. 이는 공격자가 승인되지 않은 코드를 실행하는 것을 허용할 수 있습니다.
Explanation
이 프로그램은 고유하게 식별되지 않은 사용자 정의 클래스를 참조합니다. .NET에서 이 약하게 식별된 클래스를 로드하면 CLR 유형 로더가 다음 위치에서 지정된 순서로 클래스를 검색합니다.

- 유형의 어셈블리가 알려진 경우 로더는 구성 파일의 리디렉션 위치, GAC, 구성 정보를 사용하는 현재 어셈블리 및 응용 프로그램 기본 디렉터리를 검색합니다.

- 어셈블리를 알 수 없는 경우 로더는 현재 어셈블리, mscorlib 및 TypeResolve 이벤트 처리기가 반환한 위치를 검색합니다.

이 CLR 검색 순서는 형식 전달 메커니즘 및 AppDomain.TypeResolve 이벤트와 같은 후크로 수정할 수 있습니다.

공격자가 동일한 이름을 가진 대체 클래스를 만들고 CLR이 처음으로 로드할 대체 위치에 배치하여 CLR 검색 순서를 악용하는 경우 CLR은 의도하지 않게 공격자가 제공한 코드를 실행합니다.

예제 1: 다음 WCF 구성 파일의 <behaviorExtensions/> 요소는 WCF가 특정 WCF 확장명에 사용자 지정 동작 클래스를 추가하도록 지시합니다.


<system.serviceModel>
<extensions>
<behaviorExtensions>
<add name="myBehavior" type="MyBehavior" />
</behaviorExtensions>
</extensions>
</system.serviceModel>

Abstract
약한 암호화 해시는 데이터의 무결성을 보장할 수 없고 보안이 중요한 컨텍스트에 사용되어서는 안 됩니다.
Explanation
MD2, MD4, MD5, RIPEMD-160 및 SHA-1은 메시지 및 기타 데이터의 무결성을 확인하는 데 흔히 사용되는 인기 있는 암호화 해시 알고리즘입니다. 하지만 최근의 암호화 연구를 통해 이러한 알고리즘에 근본적인 취약점이 있음이 밝혀졌으므로 더 이상 보안이 중요한 상황에 사용해서는 안 됩니다.

MD 및 RIPEMD 해시를 효과적으로 해체하기 위한 기법이 널리 사용되고 있으므로 보안을 위해 이러한 알고리즘을 신뢰해서는 안 됩니다. SHA-1의 경우, 현재의 기술은 여전히 상당한 계산 능력이 필요하며 구현하기 더 어렵습니다. 그러나 공격자는 알고리즘의 아킬레스 건을 찾아 이를 해결하는 기술로 심지어 더 빠른 공격을 발견할 수 있습니다.

Abstract
약한 암호화 해시는 데이터 무결성을 보장할 수 없으므로 보안이 중요한 컨텍스트에서 사용해서는 안 됩니다.
Explanation
MD2, MD4, MD5, RIPEMD-160 및 SHA-1은 메시지 및 기타 데이터의 무결성을 확인하는 데 흔히 사용되는 인기 있는 암호화 해시 알고리즘입니다. 암호화 연구를 통해 이러한 알고리즘에 근본적인 취약점이 있음이 밝혀졌으므로 보안이 중요한 상황에서는 이러한 알고리즘을 사용하지 않는 것이 좋습니다.

MD 및 RIPEMD 해싱 알고리즘을 보안용으로 사용하지 마십시오. MD 및 RIPEMD 해시를 효과적으로 해체하기 위한 기법이 널리 사용되고 있기 때문입니다. SHA-1의 경우, 현재의 기술은 여전히 상당한 계산 능력이 필요하며 구현하기 어렵습니다. 그러나 공격자는 알고리즘의 취약점을 찾아냈으며, 이 알고리즘을 해제하는 기술을 활용하면 더욱 빠른 공격 방식도 찾아낼 수 있습니다.

Abstract
약한 암호화 해시는 데이터의 무결성을 보장할 수 없고 보안이 중요한 컨텍스트에 사용되어서는 안 됩니다.
Explanation
MD2, MD4, MD5, RIPEMD-160 및 SHA-1은 메시지 및 기타 데이터의 무결성을 확인하는 데 흔히 사용되는 인기 있는 암호화 해시 알고리즘입니다. 하지만 최근의 암호화 연구를 통해 이러한 알고리즘에 근본적인 취약점이 있음이 밝혀졌으므로 더 이상 보안이 중요한 상황에 사용해서는 안 됩니다.

MD 및 RIPEMD 해시를 효과적으로 해체하기 위한 기법이 널리 사용되고 있으므로 보안을 위해 이러한 알고리즘을 신뢰해서는 안 됩니다. SHA-1의 경우, 현재의 기술은 여전히 상당한 계산 능력이 필요하며 구현하기 더 어렵습니다. 그러나 공격자는 알고리즘의 아킬레스 건을 찾아 이를 해결하는 기술로 심지어 더 빠른 공격을 발견할 수 있습니다.

Explanation
MD2, MD4, MD5, RIPEMD-160 및 SHA-1은 메시지 및 기타 데이터의 무결성을 확인하는 데 흔히 사용되는 인기 있는 암호화 해시 알고리즘입니다. 암호화 연구를 통해 이러한 알고리즘에 근본적인 취약점이 있음이 밝혀졌으므로 보안이 중요한 상황에서는 이러한 알고리즘을 사용하지 않는 것이 좋습니다.

MD 및 RIPEMD 해싱 알고리즘을 보안용으로 사용하지 마십시오. MD 및 RIPEMD 해시를 효과적으로 해체하기 위한 기법이 널리 사용되고 있기 때문입니다. SHA-1의 경우, 현재의 기술은 여전히 상당한 계산 능력이 필요하며 구현하기 어렵습니다. 그러나 공격자는 알고리즘의 취약점을 찾아냈으며, 이 알고리즘을 해제하는 기술을 활용하면 더욱 빠른 공격 방식도 찾아낼 수 있습니다.

Abstract
약한 암호화 해시는 데이터의 무결성을 보장할 수 없고 보안이 중요한 컨텍스트에 사용되어서는 안 됩니다.
Explanation
MD2, MD4, MD5, RIPEMD-160 및 SHA-1은 메시지 및 기타 데이터의 무결성을 확인하는 데 흔히 사용되는 인기 있는 암호화 해시 알고리즘입니다. 하지만 최근의 암호화 연구를 통해 이러한 알고리즘에 근본적인 취약점이 있음이 밝혀졌으므로 더 이상 보안이 중요한 상황에 사용해서는 안 됩니다.

MD 및 RIPEMD 해시를 효과적으로 해체하기 위한 기법이 널리 사용되고 있으므로 보안을 위해 이러한 알고리즘을 신뢰해서는 안 됩니다. SHA-1의 경우, 현재의 기술은 여전히 상당한 계산 능력이 필요하며 구현하기 더 어렵습니다. 그러나 공격자는 알고리즘의 아킬레스 건을 찾아 이를 해결하는 기술로 심지어 더 빠른 공격을 발견할 수 있습니다.

Explanation
MD2, MD4, MD5, RIPEMD-160 및 SHA-1은 메시지 및 기타 데이터의 무결성을 확인하는 데 흔히 사용되는 인기 있는 암호화 해시 알고리즘입니다. 하지만 최근의 암호화 연구를 통해 이러한 알고리즘에 근본적인 취약점이 있음이 밝혀졌으므로 더 이상 보안이 중요한 상황에 사용해서는 안 됩니다.

예제 1: 다음 코드는 약한 해시 알고리즘(MD5)을 활용합니다.


NSData *imageData = [NSData dataWithContentsOfFile:file];
CC_MD5(imageData, [imageData length], result);


MD 및 RIPEMD 해시를 효과적으로 해체하기 위한 기법이 널리 사용되고 있으므로 보안을 위해 이러한 알고리즘을 신뢰해서는 안 됩니다. SHA-1의 경우, 현재의 기술은 여전히 상당한 계산 능력이 필요하며 구현하기 더 어렵습니다. 그러나 공격자는 알고리즘의 아킬레스 건을 찾아 이를 해결하는 기술로 심지어 더 빠른 공격을 발견할 수 있습니다.

Abstract
약한 암호화 해시는 데이터의 무결성을 보장할 수 없고 보안이 중요한 컨텍스트에 사용되어서는 안 됩니다.
Explanation
MD2, MD4, MD5, RIPEMD-160 및 SHA-1은 메시지 및 기타 데이터의 무결성을 확인하는 데 흔히 사용되는 인기 있는 암호화 해시 알고리즘입니다. 하지만 최근의 암호화 연구를 통해 이러한 알고리즘에 근본적인 취약점이 있음이 밝혀졌으므로 더 이상 보안이 중요한 상황에 사용해서는 안 됩니다.

MD 및 RIPEMD 해시를 효과적으로 해체하기 위한 기법이 널리 사용되고 있으므로 보안을 위해 이러한 알고리즘을 신뢰해서는 안 됩니다. SHA-1의 경우, 현재의 기술은 여전히 상당한 계산 능력이 필요하며 구현하기 더 어렵습니다. 그러나 공격자는 알고리즘의 아킬레스 건을 찾아 이를 해결하는 기술로 심지어 더 빠른 공격을 발견할 수 있습니다.

Abstract
식별된 호출은 약한 암호화 해시를 사용합니다. 약한 암호화 해시는 데이터의 무결성을 보장할 수 없고 보안이 중요한 컨텍스트에 사용되어서는 안 됩니다.
Explanation
MD2, MD4, MD5, RIPEMD-160 및 SHA-1은 메시지 및 기타 데이터의 무결성을 확인하는 데 흔히 사용되는 인기 있는 암호화 해시 알고리즘입니다. 하지만 최근의 암호화 연구를 통해 이러한 알고리즘에 근본적인 취약점이 있음이 밝혀졌으므로 더 이상 보안이 중요한 상황에 사용해서는 안 됩니다.

예제 1: 다음 코드는 약한 해시 알고리즘(MD5)을 활용합니다.


let encodedText = text.cStringUsingEncoding(NSUTF8StringEncoding)
let textLength = CC_LONG(text.lengthOfBytesUsingEncoding(NSUTF8StringEncoding))
let digestLength = Int(CC_MD5_DIGEST_LENGTH)
let result = UnsafeMutablePointer<CUnsignedChar>.alloc(digestLength)

CC_MD5(encodedText, textLength, result)


MD 및 RIPEMD 해시를 효과적으로 해체하기 위한 기법이 널리 사용되고 있으므로 보안을 위해 이러한 알고리즘을 신뢰해서는 안 됩니다. SHA-1의 경우, 현재의 기술은 여전히 상당한 계산 능력이 필요하며 구현하기 더 어렵습니다. 그러나 공격자는 알고리즘의 아킬레스 건을 찾아 이를 해결하는 기술로 심지어 더 빠른 공격을 발견할 수 있습니다.

Abstract
암호 기반 키 파생 함수에서 사용하는 반복 횟수가 지나치게 낮습니다.
Explanation
키 파생 함수는 기본 키 및 기타 매개 변수에서 키를 파생하는 데 사용됩니다. 비밀번호 기반 키 파생 함수에서 기본 키는 비밀번호이며, 솔트 값과 반복 횟수가 기타 매개 변수로 사용됩니다. 반복 횟수가 매개 변수로 사용되어 온 이유는 비밀번호에서 키를 생성하는 비용을 늘리기 위해서였습니다. 그러므로 반복 횟수가 너무 적으면 공격자가 응용 프로그램의 "레인보우 테이블"을 계산하여 해시된 비밀번호 값을 더 쉽게 바꿀 수 있게 되므로 공격 실행 가능성이 높아집니다.

예제 1: 다음 코드에서는 반복 횟수를 50으로 사용합니다.


...
Rfc2898DeriveBytes rdb8 = new Rfc2898DeriveBytes(password, salt,50);
...


암호 기반 암호화에 낮은 반복 횟수를 사용하는 응용 프로그램은 사소한 사전 기반 공격에 노출됩니다. 특히, 암호 기반 암호화 스키마를 통해 보호하도록 되어 있는 공격 유형이 여기에 해당합니다.

Abstract
비밀번호 기반 키 파생 함수가 사용하는 알고리즘 반복 횟수가 너무 적습니다.
Explanation
키 파생 함수는 기본 키 및 기타 매개 변수에서 키를 파생하는 데 사용됩니다. 비밀번호 기반 키 파생 함수에서 기본 키는 비밀번호이며, 솔트 값과 반복 횟수가 기타 매개 변수로 사용됩니다. 반복 횟수가 매개 변수로 사용되어 온 이유는 비밀번호에서 키를 생성하는 비용을 늘리기 위해서였습니다. 그러므로 반복 횟수가 너무 적으면 공격자가 응용 프로그램의 "레인보우 테이블"을 계산하여 해시된 비밀번호 값을 더 쉽게 확인할 수 있게 되므로 공격 실행 가능성이 높아집니다.

예제 1: 다음 코드에서는 반복 횟수 50을 사용합니다.


...
const iterations = 50;
crypto.pbkdf2(
password,
salt,
iterations,
keyLength,
"sha256",
function (err, derivedKey) { ... }
);


비밀번호 기반 암호화에 사용하는 반복 횟수가 적은 응용 프로그램은 심각도가 낮은 사전 기반 공격(비밀번호 기반 암호화 체계를 통해 방지하려는 공격 유형)에 노출됩니다.

Abstract
암호 기반 키 파생 함수에서 사용하는 반복 횟수가 지나치게 낮습니다.
Explanation
키 파생 함수는 기본 키 및 기타 매개 변수에서 키를 파생하는 데 사용됩니다. 비밀번호 기반 키 파생 함수에서 기본 키는 비밀번호이며, 솔트 값과 반복 횟수가 기타 매개 변수로 사용됩니다. 반복 횟수가 매개 변수로 사용되어 온 이유는 비밀번호에서 키를 생성하는 비용을 늘리기 위해서였습니다. 그러므로 반복 횟수가 너무 적으면 공격자가 응용 프로그램의 "레인보우 테이블"을 계산하여 해시된 비밀번호 값을 더 쉽게 바꿀 수 있게 되므로 공격 실행 가능성이 높아집니다.

예제 1: 다음 코드에서는 반복 횟수를 50으로 사용합니다.


...
from hashlib import pbkdf2_hmac
dk = pbkdf2_hmac('sha256', password, salt, 50)
...


비밀번호 기반 암호화에 사용하는 반복 횟수가 적은 응용 프로그램은 심각도가 낮은 사전 기반 공격(비밀번호 기반 암호화 체계를 통해 방지하려는 공격 유형)에 노출됩니다.

예제 2: 다음 코드는 비용 매개 변수를 11로 설정합니다.

bcrypt_hash = bcrypt(b64pwd, 11)

Pycryptodome에서 bcrypt API를 사용할 때는 기본 해싱 프로세스의 계산 복잡도를 결정할 때 비용 매개 변수가 중요하다는 점을 기억해야 합니다. 충분한 보안 수준을 보장하려면 비용 매개 변수를 12 이상의 값으로 설정하는 것이 좋습니다. 이 값은 해시 계산에 소요되는 시간에 직접 영향을 주므로 높은 값을 설정하면 잠재적 공격자가 무차별 대입 또는 사전 공격을 수행하는 과정에서 발생하는 계산 비용이 증가합니다.

Abstract
비밀번호 기반 키 파생 함수가 사용하는 알고리즘 반복 횟수가 너무 적습니다.
Explanation
키 파생 함수는 기본 키 및 기타 매개 변수에서 키를 파생하는 데 사용됩니다. 비밀번호 기반 키 파생 함수에서 기본 키는 비밀번호이며, 솔트 값과 반복 횟수가 기타 매개 변수로 사용됩니다. 반복 횟수가 매개 변수로 사용되어 온 이유는 비밀번호에서 키를 생성하는 비용을 늘리기 위해서였습니다. 그러므로 반복 횟수가 너무 적으면 공격자가 응용 프로그램의 "레인보우 테이블"을 계산하여 해시된 비밀번호 값을 더 쉽게 바꿀 수 있게 되므로 공격 실행 가능성이 높아집니다.

예제 1: 다음 XML은 반복 횟수를 50으로 구성합니다.


...
<param name="keyObtentionIterations" value="50"/>
...


비밀번호 기반 암호화에 사용하는 반복 횟수가 적은 응용 프로그램은 심각도가 낮은 사전 기반 공격(비밀번호 기반 암호화 체계를 통해 방지하려는 공격 유형)에 노출됩니다.

Abstract
솔트 값은 암호화 의사 난수 발생기를 사용하여 생성해야 합니다.
Explanation
솔트 값은 암호화 의사 난수 발생기를 사용하여 생성해야 합니다. 난수 솔트 값을 사용하지 않으면 결과로 생성되는 해시 또는 HMAC를 예측하기가 훨씬 쉬워지고 사전 공격(Dictionary Attack)에 더 취약해집니다.

예제 1: 다음 코드에서는 암호를 솔트로 재사용합니다.

Abstract
솔트 값은 암호화 의사 난수 발생기를 사용하여 생성해야 합니다.
Explanation
솔트 값은 암호화 의사 난수 발생기를 사용하여 생성해야 합니다. 난수 솔트 값을 사용하지 않으면 결과로 생성되는 해시 또는 HMAC를 예측하기가 훨씬 쉬워지고 사전 공격(Dictionary Attack)에 더 취약해집니다.

예제 1: 다음 코드에서는 암호를 솔트로 재사용합니다.



function register(){
$password = $_GET['password'];
$username = $_GET['username'];

$hash = hash_pbkdf2('sha256', $password, $password, 100000);

Abstract
암호화 해시 내에 사용자가 제어하는 알고리즘을 사용하면 공격자가 약한 암호화 해시 알고리즘을 지정하여 응용 프로그램의 데이터 무결성과 보안을 침해할 수 있습니다.
Explanation
약한 암호화 해시: 사용자 제어 알고리즘 문제는 다음과 같은 경우에 발생합니다.

1. 신뢰할 수 없는 소스를 통해 데이터가 프로그램에 입력됩니다.

2. 사용자가 제어하는 데이터가 암호화 해시 알고리즘을 지정하는 데 사용됩니다.

여러 소프트웨어 보안 취약점과 마찬가지로 약한 암호화 해시: 사용자 제어 알고리즘은 목적의 수단일 뿐 목적 자체는 아닙니다. 이 취약점은 본질적으로 간단 명료합니다. 즉, 공격자가 응용 프로그램에 악성 데이터를 전달하며 이 데이터가 암호화 해시 알고리즘을 지정하는 데 사용됩니다. 공격자는 응용 프로그램의 데이터 무결성 및 보안을 침해하기 위해 알려진 취약점이 있는 MD5 같은 해시 알고리즘을 지정할 수 있습니다.

예제 1: 다음 코드에서는 사용자 제어 알고리즘을 사용합니다.

...
string hashname = ConfigurationManager.AppSettings["hash"];
...
HashAlgorithm ha = HashAlgorithm.Create(hashname);
...
Example 1의 코드는 성공적으로 실행되지만 이 기능을 사용할 수 있는 사용자라면 누구나 hash 속성을 수정하여 해시 알고리즘을 조작할 수 있습니다. 프로그램을 공개한 후에는 악의적인 사용자가 특정 암호화 해시의 알고리즘 매개 변수를 알아내었는지 여부를 파악하기가 상당히 어렵기 때문에 사용자 제어 알고리즘과 관련된 문제를 되돌리기가 힘들 수 있습니다.

Abstract
감염될 수 있는 사용자 입력을 PBKDF에 솔트 매개 변수로 전달해서는 안 됩니다.
Explanation
약한 암호화 해시: 사용자 제어 PBE 솔트 문제는 다음과 같은 경우에 발생합니다.

1. 신뢰할 수 없는 소스를 통해 데이터가 프로그램에 입력됩니다.

2. PBKDF 내에서 사용자가 제어하는 데이터가 솔트 내에 포함되거나 전체 솔트로 사용됩니다.


여러 소프트웨어 보안 취약점과 마찬가지로 약한 암호화 해시: 사용자 제어 PBE 솔트는 목적의 수단일 뿐 목적 자체는 아닙니다. 이 취약점은 본질적으로 간단 명료합니다. 즉, 공격자가 응용 프로그램에 악성 데이터를 전달하며 이 데이터가 PBKDF에서 솔트의 전체 또는 일부로 사용됩니다.

사용자 정의 솔트가 있을 때의 문제는 다양한 공격이 가능해질 수 있다는 점입니다.

1. 공격자는 이 취약점을 사용하여 자신의 암호에 대한 빈 솔트를 지정할 수 있습니다. 이렇게 되면 여러 암호 기반 키 파생 함수를 사용하여 자신의 암호를 빠르게 파생할 수 있기 때문에 응용 프로그램 내에서 사용되는 PBKDF 구현에 대한 정보가 누출될 수 있습니다. 이에 따라 사용되는 특정 해시 변형을 제한할 수 있게 되어 다른 암호를 "크랙"할 수 있습니다.
2. 공격자가 다른 사용자의 솔트를 조작할 수 있거나 다른 사용자가 빈 솔트를 사용하도록 속일 수 있다면, 응용 프로그램에 대한 "레인보우 테이블"을 계산하여 파생된 값을 더 쉽게 알아낼 수 있게 됩니다.

예제 1: 다음 코드에서는 사용자 제어 솔트를 사용합니다.

string salt = ConfigurationManager.AppSettings["salt"];
...
Rfc2898DeriveBytes rfc = new Rfc2898DeriveBytes("password", Encoding.ASCII.GetBytes(salt));
...
Example 1의 코드는 성공적으로 실행되지만 이 기능을 사용할 수 있는 사용자라면 누구나 salt의 속성을 수정하여 키 또는 암호를 파생하는 데 사용되는 솔트를 조작할 수 있습니다. 프로그램을 공개한 후에는 악의적인 사용자가 암호 해시의 솔트를 알아내었는지 여부를 파악하기가 극도로 어렵기 때문에 사용자 제어 솔트와 관련된 문제를 되돌리기가 힘들 수 있습니다.

Abstract
감염될 수 있는 사용자 입력을 PBKDF에 솔트 매개 변수로 전달해서는 안 됩니다.
Explanation
약한 암호화 해시: 사용자 제어 PBE 솔트 이슈는 다음과 같은 경우에 발생합니다.

1. 신뢰할 수 없는 소스를 통해 데이터가 프로그램에 입력됩니다.

2. PBKDF 내에서 사용자가 제어하는 데이터가 솔트 내에 포함되거나 전체 솔트로 사용됩니다.


여러 소프트웨어 보안 취약점과 마찬가지로 약한 암호화 해시: 사용자 제어 PBE 솔트는 목적 달성을 위한 수단이며 그 자체가 목적은 아닙니다. 이 취약점은 본질적으로 간단 명료합니다. 즉, 공격자가 응용 프로그램에 악성 데이터를 전달하며 이 데이터가 PBKDF에서 솔트의 전체 또는 일부로 사용됩니다.

사용자 정의 솔트가 있을 때의 문제는 다양한 공격이 가능해질 수 있다는 점입니다.

1. 공격자는 이 취약점을 사용하여 자신의 비밀번호에 대한 빈 솔트를 지정할 수 있습니다. 이렇게 되면 여러 비밀번호 기반 키 파생 함수를 사용하여 자신의 비밀번호를 빠르게 파생할 수 있기 때문에 응용 프로그램 내에서 사용되는 PBKDF 구현에 대한 정보가 누출될 수 있습니다. 이에 따라 사용되는 특정 해시 변형을 제한할 수 있게 되어 다른 비밀번호를 "크랙"할 수 있습니다.
2. 공격자가 다른 사용자의 솔트를 조작할 수 있거나 다른 사용자가 빈 솔트를 사용하도록 속일 수 있다면, 응용 프로그램에 대한 "레인보우 테이블"을 계산하여 파생된 값을 더 쉽게 알아낼 수 있게 됩니다.

예제 1: 다음 코드는 사용자 제어 솔트를 사용합니다.

app.get('/pbkdf2', function(req, res) {
...
let salt = req.params['salt'];
crypto.pbkdf2(
password,
salt,
iterations,
keyLength,
"sha256",
function (err, derivedKey) { ... }
);
}
Example 1의 코드는 성공적으로 실행되지만 이 기능을 사용할 수 있는 사용자라면 누구나 salt의 속성을 수정하여 키 또는 암호를 파생하는 데 사용되는 솔트를 조작할 수 있습니다. 프로그램을 공개한 후에는 악의적인 사용자가 암호 해시의 솔트를 알아내었는지 여부를 파악하기가 극도로 어렵기 때문에 사용자 제어 솔트와 관련된 문제를 되돌리기가 힘들 수 있습니다.

Abstract
감염될 수 있는 사용자 입력을 PBKDF에 솔트 매개 변수로 전달해서는 안 됩니다.
Explanation
약한 암호화 해시: 사용자 제어 PBE 솔트 이슈는 다음과 같은 경우에 발생합니다.

1. 신뢰할 수 없는 소스를 통해 데이터가 프로그램에 입력됩니다.

2. PBKDF 내에서 사용자가 제어하는 데이터가 솔트 내에 포함되거나 전체 솔트로 사용됩니다.


여러 소프트웨어 보안 취약점과 마찬가지로 약한 암호화 해시: 사용자 제어 PBE 솔트는 목적 달성을 위한 수단이며 그 자체가 목적은 아닙니다. 이 취약점은 본질적으로 간단 명료합니다. 즉, 공격자가 응용 프로그램에 악성 데이터를 전달하며 이 데이터가 PBKDF에서 솔트의 전체 또는 일부로 사용됩니다.

사용자 정의 솔트가 있을 때의 문제는 다양한 공격이 가능해질 수 있다는 점입니다.

1. 공격자는 이 취약점을 사용하여 자신의 암호에 대한 빈 솔트를 지정할 수 있습니다. 이렇게 되면 여러 암호 기반 키 파생 함수를 사용하여 자신의 암호를 빠르게 파생할 수 있기 때문에 응용 프로그램 내에서 사용되는 PBKDF 구현에 대한 정보가 누출될 수 있습니다. 이에 따라 사용되는 특정 해시 변형을 제한할 수 있게 되어 다른 암호를 "크랙"할 수 있습니다.
2. 공격자가 다른 사용자의 솔트를 조작할 수 있거나 다른 사용자가 빈 솔트를 사용하도록 속일 수 있다면, 응용 프로그램에 대한 "레인보우 테이블"을 계산하여 파생된 값을 더 쉽게 알아낼 수 있게 됩니다.

예제 1: 다음 코드에서는 사용자 제어 솔트를 사용합니다.


function register(){
$password = $_GET['password'];
$username = $_GET['username'];
$salt = getenv('SALT');

$hash = hash_pbkdf2('sha256', $password, $salt, 100000);
...
Example 1의 코드는 성공적으로 실행되지만 이 기능을 사용할 수 있는 사용자라면 누구나 SALT 환경 변수를 수정하여 키 또는 암호를 파생하는 데 사용되는 솔트를 조작할 수 있습니다. 프로그램을 공개한 후에는 악의적인 사용자가 암호 해시의 솔트를 알아내었는지 여부를 파악하기가 극도로 어렵기 때문에 사용자 제어 솔트와 관련된 문제를 되돌리기가 힘들 수 있습니다.

Abstract
감염될 수 있는 사용자 입력을 PBKDF에 솔트 매개 변수로 전달해서는 안 됩니다.
Explanation
약한 암호화 해시: 사용자 제어 PBE 솔트 문제는 다음과 같은 경우에 발생합니다.

1. 신뢰할 수 없는 소스를 통해 데이터가 프로그램에 입력됩니다.

2. PBKDF 내에서 사용자가 제어하는 데이터가 솔트 내에 포함되거나 전체 솔트로 사용됩니다.


여러 소프트웨어 보안 취약점과 마찬가지로 약한 암호화 해시: 사용자 제어 PBE 솔트는 목적의 수단일 뿐 목적 자체는 아닙니다. 이 취약점은 본질적으로 간단 명료합니다. 즉, 공격자가 응용 프로그램에 악성 데이터를 전달하며 이 데이터가 PBKDF에서 솔트의 전체 또는 일부로 사용됩니다.

사용자 정의 솔트가 있을 때의 문제는 다양한 공격이 가능해질 수 있다는 점입니다.

1. 공격자는 이 취약점을 사용하여 자신의 암호에 대한 빈 솔트를 지정할 수 있습니다. 이렇게 되면 여러 암호 기반 키 파생 함수를 사용하여 자신의 암호를 빠르게 파생할 수 있기 때문에 응용 프로그램 내에서 사용되는 PBKDF 구현에 대한 정보가 누출될 수 있습니다. 이에 따라 사용되는 특정 해시 변형을 제한할 수 있게 되어 다른 암호를 "크랙"할 수 있습니다.
2. 공격자가 다른 사용자의 솔트를 조작할 수 있거나 다른 사용자가 빈 솔트를 사용하도록 속일 수 있다면, 응용 프로그램에 대한 "레인보우 테이블"을 계산하여 파생된 값을 더 쉽게 알아낼 수 있게 됩니다.

예제 1: 다음 코드는 사용자 제어 솔트를 사용합니다.

...
@IBOutlet weak var inputTextField : UITextField!
...
let salt = (inputTextField.text as NSString).dataUsingEncoding(NSUTF8StringEncoding)
let saltPointer = UnsafePointer<UInt8>(salt.bytes)
let saltLength = size_t(salt.length)
...
let algorithm : CCPBKDFAlgorithm = CCPBKDFAlgorithm(kCCPBKDF2)
let prf : CCPseudoRandomAlgorithm = CCPseudoRandomAlgorithm(kCCPRFHmacAlgSHA256)
CCKeyDerivationPBKDF(algorithm,
passwordPointer,
passwordLength,
saltPointer,
saltLength,
prf,
100000,
derivedKeyPointer,
derivedKeyLength)
...
Example 1의 코드는 성공적으로 실행되지만 이 기능을 사용할 수 있는 사용자는 누구든지 UITextField inputTextField의 텍스트를 수정하여 키 또는 암호를 파생하는 데 사용되는 솔트를 조작할 수 있습니다. 프로그램을 공개한 후에는 악의적인 사용자가 암호 해시의 솔트를 알아내었는지 여부를 파악하기가 극도로 어렵기 때문에 사용자 제어 솔트와 관련된 문제를 되돌리기가 힘들 수 있습니다.

Abstract
불충분한 키 크기를 사용하면 강력한 암호화 서명 알고리즘이더라도 무차별 대입 공격에 크게 취약해질 수 있습니다.

예제 1: 다음 코드에서는 1024비트 DSA 서명 키를 생성합니다.

Abstract
불충분한 키 크기를 사용하면 강력한 암호화 서명 알고리즘이더라도 무차별 대입 공격에 크게 취약해집니다.
Explanation
현재 암호 작성법 지침에 따르면 RSA 및 DSA 알고리즘과 함께 적어도 2048비트의 키 길이를 사용해야 합니다. 하지만 계산 기능과 인수 분해 기술[1]이 지속적으로 발전하기 때문에 나중에는 권장되는 키 크기가 분명 더 커질 것입니다.

예제 1: 다음 코드에서는 1024비트 DSA 서명 키를 생성합니다.

...
dsa.GenerateParameters(params, rand.Reader, dsa.L1024N160)
privatekey := new(dsa.PrivateKey)
privatekey.PublicKey.Parameters = *params
dsa.GenerateKey(privatekey, rand.Reader)
...

Abstract
키 크기 매개 변수를 사용하는 암호화 서명 함수에 감염된 키 크기 값을 전달해서는 안 됩니다.
Explanation
사용자가 제어하는 값을 통해 키 크기를 결정할 수 있도록 허용하면 공격자가 빈 키를 지정하여 암호화된 데이터의 무결성을 유지하는 암호화 서명을 수정하게 될 수도 있습니다. 0이 아닌 값을 지정해야 하더라도 공격자는 여전히 키 크키 값을 최대한 낮게 지정하여 암호화된 데이터의 무결성을 떨어뜨릴 수 있습니다.

약한 암호화 해시: 사용자 제어 키 크기 문제는 다음과 같은 경우에 발생합니다.

1. 신뢰할 수 없는 소스를 통해 데이터가 프로그램에 입력됩니다.

2. 암호화 서명 함수 내에서 키 크기 매개 변수의 전체 또는 일부로 사용자가 제어하는 데이터가 사용됩니다.

여러 소프트웨어 보안 취약점과 마찬가지로 약한 암호화 해시: 사용자 제어 키 크기는 목적의 수단일 뿐 목적 자체는 아닙니다. 이 취약점은 본질적으로 간단 명료합니다. 즉, 공격자가 응용 프로그램에 악성 데이터를 전달하며 이 데이터가 암호화를 수행하는 동안 키 크기 값의 전체 또는 일부로 사용됩니다.

현재 암호 작성법 지침에 따르면 RSA 및 DSA 알고리즘과 함께 적어도 2048비트의 키 길이를 사용해야 합니다. 하지만 계산 기능과 인수 분해 기술[1]이 지속적으로 발전하기 때문에 나중에는 권장되는 키 크기가 분명 더 커질 것입니다. 사용자 입력이 키 크기 값에 부분적으로만 사용되더라도 서명의 보안을 크게 약화시킬 수 있으므로 암호화된 데이터의 무결성도 대폭 떨어뜨릴 수 있습니다.

예제 1: 다음 코드에서는 사용자 제어 키 크기 매개 변수를 사용하여 DSA 서명 키를 생성합니다.

...
DSA dsa1 = new DSACryptoServiceProvider(Convert.ToInt32(TextBox1.Text));
...


사용자가 key_len을 확인할 수 있어야 하는 사용 사례는 거의 없으며, 설령 있다고 하더라도 해당 값이 숫자 값이며 적절한 키 크기 값 범위 내에 있는지 모두 확인하도록 적절한 보호 조치를 취해야 합니다. 대부분의 경우 이는 충분히 높은 하드코드된 숫자여야 합니다.

사용자가 key_len을 확인할 수 있어야 하는 사용 사례는 거의 없으며, 설령 있다고 하더라도 해당 값이 숫자 값이며 적절한 키 크기 값 범위 내에 있는지 모두 확인하도록 적절한 보호 조치를 취해야 합니다. 대부분의 경우 이는 충분히 높은 하드코드된 숫자여야 합니다.

Abstract
식별된 호출은 민감한 데이터의 기밀성을 보장할 수 없는 약한 암호화 알고리즘을 사용합니다.
Explanation
DES와 같은 오래된 암호화 알고리즘은 더 이상 민감한 데이터와 함께 사용할 충분한 보호 기능을 제공하지 않습니다. 암호화 알고리즘은 암호화 능력을 보장하는 기본 메커니즘 중 하나로 키 크기에 의존합니다. 암호화 능력은 흔히 유효한 키를 생성하는 데 필요한 계산 능력 및 시간으로 측정됩니다. 계산 기능의 발전으로 인해 적당한 시간에 작은 암호화 키를 얻을 수 있게 되었습니다. 예를 들어, DES에 사용되는 56비트 키는 알고리즘이 처음 개발된 1970년대에는 상당한 계산상의 장애물을 내포했지만 오늘날 DES는 일반적으로 사용 가능한 장비를 사용하여 하루도 안 돼 균열될 수 있습니다.

Abstract
식별된 호출은 민감한 데이터의 기밀성을 보장할 수 없는 약한 암호화 알고리즘을 사용합니다.
Explanation
DES와 같은 오래된 암호화 알고리즘은 더 이상 민감한 데이터와 함께 사용할 충분한 기능을 제공하지 않습니다. 암호화 알고리즘은 암호화 능력을 보장하는 기본 메커니즘 중 하나로 키 크기에 의존합니다. 암호화 능력은 흔히 유효한 키를 생성하는 데 필요한 계산 능력 및 시간으로 측정됩니다. 계산 기능의 발전으로 인해 적당한 시간에 작은 암호화 키를 얻을 수 있게 되었습니다. 예를 들어, DES에 사용되는 56비트 키는 알고리즘이 처음 개발된 1970년대에는 상당한 계산상의 장애물을 내포했지만 오늘날 DES는 일반적으로 사용 가능한 장비를 사용하여 하루도 안 돼 균열될 수 있습니다.

Abstract
식별된 호출은 민감한 데이터의 기밀성을 보장할 수 없는 약한 암호화 알고리즘을 사용합니다.
Explanation
DES와 같은 오래된 암호화 알고리즘은 더 이상 민감한 데이터와 함께 사용할 충분한 기능을 제공하지 않습니다. 암호화 알고리즘은 암호화 능력을 보장하는 기본 메커니즘 중 하나로 키 크기에 의존합니다. 암호화 능력은 흔히 유효한 키를 생성하는 데 필요한 계산 능력 및 시간으로 측정됩니다. 계산 기능의 발전으로 인해 적당한 시간에 작은 암호화 키를 얻을 수 있게 되었습니다. 예를 들어, DES에 사용되는 56비트 키는 알고리즘이 처음 개발된 1970년대에는 상당한 계산상의 장애물을 내포했지만 오늘날 DES는 일반적으로 사용 가능한 장비를 사용하여 하루도 안 돼 균열될 수 있습니다.

Abstract
식별된 호출은 민감한 데이터의 기밀성을 보장할 수 없는 약한 암호화 알고리즘을 사용합니다.
Explanation
크기가 부족한 키를 사용하는 알고리즘 같은 오래된 암호화 알고리즘은 더 이상 민감한 데이터와 함께 사용할 만큼 보호 기능을 충분히 제공하지 않습니다. 계산 기술의 발전으로 인해 적당한 시간에 무차별 대입을 통해 작은 암호화 키를 얻을 수 있게 되었기 때문입니다. 예를 들어, 알고리즘이 처음 개발된 1970년대에 DES에 사용된 64 비트 키는 중요한 계산 장애물을 내포했지만, 오늘날 DES는 일반적으로 사용 가능한 장비를 사용하여 하루도 안 돼 크랙할 수 있습니다.

Abstract
이 프로그램은 민감한 데이터의 기밀성을 보장할 수 없는 약한 암호화 알고리즘을 사용합니다.
Explanation
DES와 같은 오래된 암호화 알고리즘은 더 이상 민감한 데이터와 함께 사용할 충분한 기능을 제공하지 않습니다. 암호화 알고리즘은 암호화 능력을 보장하는 기본 메커니즘 중 하나로 키 크기에 의존합니다. 암호화 능력은 흔히 유효한 키를 생성하는 데 필요한 계산 능력 및 시간으로 측정됩니다. 계산 기능의 발전으로 인해 적당한 시간에 작은 암호화 키를 얻을 수 있게 되었습니다. 예를 들어, DES에 사용되는 56비트 키는 알고리즘이 처음 개발된 1970년대에는 상당한 계산상의 장애물을 내포했지만 오늘날 DES는 일반적으로 사용 가능한 장비를 사용하여 하루도 안 돼 균열될 수 있습니다.

Abstract
식별된 호출은 민감한 데이터의 기밀성을 보장할 수 없는 약한 암호화 알고리즘을 사용합니다.
Explanation
크기가 부족한 키를 사용하는 알고리즘 같은 오래된 암호화 알고리즘은 더 이상 민감한 데이터와 함께 사용할 만큼 보호 기능을 충분히 제공하지 않습니다. 계산 기술의 발전으로 인해 적당한 시간에 무차별 대입을 통해 작은 암호화 키를 얻을 수 있게 되었기 때문입니다. 예를 들어, 알고리즘이 처음 개발된 1970년대에 DES에 사용된 64 비트 키는 중요한 계산 장애물을 내포했지만, 오늘날 DES는 일반적으로 사용 가능한 장비를 사용하여 하루도 안 돼 크랙할 수 있습니다.

예제 1: 다음 코드는 안전하지 않은 알고리즘(DES)으로 암호화를 수행합니다.

Abstract
중요한 데이터의 기밀성을 보장할 수 없는 약한 암호화 알고리즘이 구성되어 있습니다.
Explanation
DES와 같은 오래된 암호화 알고리즘은 더 이상 민감한 데이터와 함께 사용할 충분한 기능을 제공하지 않습니다. 암호화 알고리즘은 암호화 능력을 보장하는 기본 메커니즘 중 하나로 키 크기에 의존합니다. 암호화 능력은 흔히 유효한 키를 생성하는 데 필요한 계산 능력 및 시간으로 측정됩니다. 계산 기능의 발전으로 인해 적당한 시간에 작은 암호화 키를 얻을 수 있게 되었습니다. 예를 들어, DES에 사용되는 56비트 키는 알고리즘이 처음 개발된 1970년대에는 상당한 계산상의 장애물을 내포했지만 오늘날 DES는 일반적으로 사용 가능한 장비를 사용하여 하루도 안 돼 균열될 수 있습니다.

Abstract
공용 키 RSA 암호화는 OAEP 패딩을 사용하지 않고 수행되므로 암호화가 취약해집니다.
Explanation
실제로, RSA 공용 키를 사용한 암호화는 대개 패딩 스키마와 함께 사용됩니다. 패딩 스키마를 사용하면 암호화가 패딩 없이 수행될 때만 작동하는 RSA에 대한 공격을 예방할 수 있습니다.

예제 1: 다음 코드에서는 패딩 스키마를 사용하지 않는 RSA 공용 키로 암호화를 수행합니다.

static public byte[] EncryptWithRSA(byte[] plaintext, RSAParameters key) {
try {
RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();
rsa.ImportParameters(key);
return rsa.Encrypt(plaintext, false);
}
catch(CryptographicException e) {
Console.WriteLine(e.Message);
return null;
}
}

Abstract
공용 키 RSA 암호화는 OAEP 패딩을 사용하지 않고 수행되므로 암호화가 취약해집니다.
Explanation
실제로, RSA 공용 키를 사용한 암호화는 대개 패딩 스키마와 함께 사용됩니다. 패딩 스키마를 사용하면 암호화가 패딩 없이 수행될 때만 작동하는 RSA에 대한 공격을 예방할 수 있습니다.

예제 1: 다음 코드에서는 패딩 스키마를 사용하지 않는 RSA 공용 키로 암호화를 수행합니다.

Abstract
공용 키 RSA 암호화는 OAEP 패딩을 사용하지 않고 수행되므로 암호화가 취약해집니다.
Explanation
실제로, RSA 공용 키를 사용한 암호화는 대개 패딩 스키마와 함께 사용됩니다. 패딩 스키마를 사용하면 암호화가 패딩 없이 수행될 때만 작동하는 RSA에 대한 공격을 예방할 수 있습니다.

예제 1: 다음 코드에서는 패딩 스키마를 사용하지 않는 RSA 공용 키로 암호화를 수행합니다.

function encrypt($input, $key) {
$output='';
openssl_public_encrypt($input, $output, $key, OPENSSL_NO_PADDING);
return $output;
}

key = OpenSSL::PKey::RSA.new 2048
public_encrypted = key.public_encrypt(data) #padding type not specified

Example 1에서 OpenSSL::PKey::RSA#public_encrypt는 문자열로만 호출되며 사용할 패딩 유형을 지정하지 않습니다. 패딩의 기본값은 OpenSSL::PKey::RSA::PKCS1_PADDING입니다.

Abstract
공용 키 RSA 암호화는 OAEP 패딩을 사용하지 않고 수행되므로 암호화가 취약해집니다.
Explanation
실제로, RSA 공용 키를 사용한 암호화는 대개 패딩 스키마와 함께 사용됩니다. 패딩 스키마를 사용하면 암호화가 패딩 없이 수행될 때만 작동하는 RSA에 대한 공격을 예방할 수 있습니다.

예제 1: 다음 코드에서는 패딩 스키마를 사용하지 않는 RSA 공용 키로 암호화를 수행합니다.

func encrypt(data plaintextData:Data, publicKey:SecKey) throws -> Data {
var error: Unmanaged<CFError>?
guard let ciphertextData = SecKeyCreateEncryptedData(publicKey,
.rsaEncryptionPKCS1,
plaintextData as CFData,
&error) else {
throw error!.takeRetainedValue() as Error
}
return ciphertextData as Data;
}

Abstract
암호화 의사 난수 발생기를 사용하여 IV(Initialization Vector)를 만듭니다.
Explanation
암호화 의사 난수 발생기를 사용하여 IV(Initialization Vector)를 만듭니다. 이렇게 하지 않으면 결과 암호화 텍스트를 더 예측하기가 쉬워지고 사전 공격(Dictionary Attack)에 취약해집니다.

예제 1: 다음 코드에서는 키를 IV로 재사용합니다.


import (
"crypto/aes"
"crypto/cipher"
"crypto/rand"
)
...
block, err := aes.NewCipher(key)
...
mode := cipher.NewCBCEncrypter(block, key)
mode.CryptBlocks(ciphertext[aes.BlockSize:], plaintext)


키를 IV로 사용하면 공격자가 키를 복구하여 데이터를 해독할 수 있습니다.

Abstract
IV(Initialization Vector)는 암호화 의사 난수 발생기를 사용하여 생성해야 합니다.
Explanation
IV(Initialization Vector)는 암호화 의사 난수 발생기를 사용하여 생성해야 합니다. 난수 IV를 사용하지 않으면 결과 암호화 텍스트를 더 예측하기가 쉬워지고 사전 공격(Dictionary Attack)에 더 취약해집니다.

예제 1: 다음 코드는 하드코드된 바이트를 사용하여 무작위가 아닌 IV를 생성합니다.


...
NSString *iv = @"1234567812345678"; //Bad idea to hard code IV
char ivPtr[kCCBlockSizeAES128];

[iv getCString:ivPtr maxLength:sizeof(ivPtr) encoding:NSASCIIStringEncoding];
...
ccStatus = CCCrypt( kCCEncrypt,
kCCAlgorithmAES128,
kCCOptionPKCS7Padding,
[key cStringUsingEncoding:NSASCIIStringEncoding],
kCCKeySizeAES128,
[ivPtr], /*IV should be something random (not null and not constant)*/
[self bytes], dataLength, /* input */
buffer, bufferSize, /* output */
&numBytesEncrypted
);


또한 CCCrypt를 호출할 때 CBC 모드를 선택하고 IV를 제공하지 않은 경우(nil) 0만 포함된 IV가 사용됩니다.

Abstract
IV(Initialization Vector)는 암호화 의사 난수 발생기를 사용하여 생성해야 합니다.
Explanation
IV(Initialization Vector)는 암호화 의사 난수 발생기를 사용하여 생성해야 합니다. 난수 IV를 사용하지 않으면 결과 암호화 텍스트를 더 예측하기가 쉬워지고 사전 공격(Dictionary Attack)에 더 취약해집니다.

예제 1: 다음 코드에서는 키를 IV로 재사용합니다.


from Crypto.Cipher import AES
from Crypto import Random
...
key = Random.new().read(AES.block_size)
cipher = AES.new(key, AES.MODE_CTR, IV=key)


키를 IV로 사용하면 공격자가 키를 복구하여 데이터를 해독할 수 있습니다.

Abstract
안전하지 않은 작업 모드로 암호화 알고리즘을 사용하지 마십시오.
Explanation
블록 암호 작업 모드는 암호의 단일 블록 작업을 반복해서 적용하여 블록보다 많은 양의 데이터를 안전하게 변환하는 방법을 설명하는 알고리즘입니다. 일부 작업 모드에는 ECB(Electronic Codebook), CBC(Cipher Block Chaining), CFB(Cipher Feedback) 및 CTR(Counter)이 포함됩니다.

ECB 모드는 동일한 일반 텍스트 블록에 대해 같은 암호화 텍스트를 생성하므로 본질적으로 취약합니다. CBC 모드는 Padding Oracle 공격에 취약합니다. CTR 모드에는 이러한 취약점이 없으므로 이 모드를 선택하는 것이 더 적절합니다.

예제 1: 다음 코드에서는 AES 암호를 ECB 모드로 사용합니다.


...
var objAesCryptoService = new AesCryptoServiceProvider();
objAesCryptoService.Mode = CipherMode.ECB;
objAesCryptoService.Padding = PaddingMode.PKCS7;
objAesCryptoService.Key = securityKeyArray;
var objCrytpoTransform = objAesCryptoService.CreateEncryptor();
...

Abstract
안전하지 않은 작업 모드로 암호화 알고리즘을 사용하지 마십시오.
Explanation
블록 암호 작업 모드는 암호의 단일 블록 작업을 반복해서 적용하여 블록보다 많은 양의 데이터를 안전하게 변환하는 방법을 설명하는 알고리즘입니다. 일부 작업 모드에는 ECB(Electronic Codebook), CBC(Cipher Block Chaining), CFB(Cipher Feedback) 및 CTR(Counter)이 포함됩니다.

ECB 모드는 동일한 일반 텍스트 블록에 대해 같은 암호화 텍스트를 생성하므로 본질적으로 취약합니다. CBC 모드는 Padding Oracle 공격에 취약합니다. CTR 모드에는 이러한 취약점이 없으므로 이 모드를 선택하는 것이 더 적절합니다.

예제 1: 다음 코드에서는 AES 암호를 ECB 모드로 사용합니다.

Abstract
식별된 호출은 민감한 데이터의 기밀성을 보장할 수 없는 약한 암호화 알고리즘을 사용합니다.
Explanation
DES와 같은 오래된 암호화 알고리즘은 더 이상 민감한 데이터와 함께 사용할 충분한 기능을 제공하지 않습니다. 암호화 알고리즘은 암호화 능력을 보장하는 기본 메커니즘 중 하나로 키 크기에 의존합니다. 암호화 능력은 흔히 유효한 키를 생성하는 데 필요한 계산 능력 및 시간으로 측정됩니다. 계산 기능의 발전으로 인해 적당한 시간에 작은 암호화 키를 얻을 수 있게 되었습니다. 예를 들어, DES에 사용되는 56비트 키는 알고리즘이 처음 개발된 1970년대에는 상당한 계산상의 장애물을 내포했지만 오늘날 DES는 일반적으로 사용 가능한 장비를 사용하여 하루도 안 돼 균열될 수 있습니다.

Abstract
안전하지 않은 작업 모드로 암호화 알고리즘을 사용하지 마십시오.
Explanation
블록 암호 작업 모드는 암호의 단일 블록 작업을 반복해서 적용하여 블록보다 많은 양의 데이터를 안전하게 변환하는 방법을 설명하는 알고리즘입니다. 일부 작업 모드에는 ECB(Electronic Codebook), CBC(Cipher Block Chaining), CFB(Cipher Feedback) 및 CTR(Counter)이 포함됩니다.

ECB 모드는 동일한 일반 텍스트 블록에 대해 같은 암호화 텍스트를 생성하므로 본질적으로 취약합니다. CBC 모드는 Padding Oracle 공격에 취약합니다. CTR 모드에는 이러한 취약점이 없으므로 이 모드를 선택하는 것이 더 적절합니다.

예제 1: 다음 코드에서는 AES 암호를 ECB 모드로 사용합니다.

Abstract
안전하지 않은 작업 모드로 암호화 알고리즘을 사용하지 마십시오.
Explanation
블록 암호 작업 모드는 암호의 단일 블록 작업을 반복해서 적용하여 블록보다 많은 양의 데이터를 안전하게 변환하는 방법을 설명하는 알고리즘입니다. 일부 작업 모드에는 ECB(Electronic Codebook), CBC(Cipher Block Chaining), CFB(Cipher Feedback) 및 CTR(Counter)이 포함됩니다.

ECB 모드는 동일한 일반 텍스트 블록에 대해 같은 암호화 텍스트를 생성하므로 본질적으로 취약합니다. CBC 모드는 Padding Oracle 공격에 취약합니다. CTR 모드에는 이러한 취약점이 없으므로 이 모드를 선택하는 것이 더 적절합니다.

예제 1: 다음 코드에서는 AES 암호를 ECB 모드로 사용합니다.

Abstract
불충분한 키 크기를 사용하면 강력한 암호화 알고리즘이더라도 무차별 대입 공격에 크게 취약해질 수 있습니다.
Explanation
현재 암호 작성법 지침에 따르면 RSA 알고리즘과 함께 적어도 2048비트의 키 길이를 사용해야 합니다. 하지만 계산 기능과 인수 분해 기술[1]이 지속적으로 발전하기 때문에 나중에는 권장되는 키 크기가 분명 더 커질 것입니다.

예제 1: 다음 코드는 512비트 암호화 키를 가진 RSA 알고리즘을 사용합니다.

static public byte[] EncryptWithRSA(byte[] plaintext, RSAParameters key) {
try {
RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(512);
rsa.ImportParameters(key);
return rsa.Encrypt(plaintext, true);
}
catch(CryptographicException e) {
Console.WriteLine(e.Message);
return null;
}
}


대칭 암호화의 경우 키 길이가 적어도 128비트여야 합니다.

Abstract
불충분한 키 크기를 사용하면 강력한 암호화 알고리즘이더라도 무차별 대입 공격에 크게 취약해질 수 있습니다.
Explanation
현재 암호 작성법 지침에 따르면 RSA 알고리즘과 함께 적어도 2048비트의 키 길이를 사용해야 합니다. 대칭 암호화의 경우 키 길이가 적어도 128비트여야 합니다. 하지만 계산 기능과 인수 분해 기술[1]이 지속적으로 발전하기 때문에 나중에는 권장되는 키 크기가 분명 더 커질 것입니다.

예제 1: 다음 코드는 1024비트 RSA 키를 생성합니다.

...
myPrivateKey := rsa.GenerateKey(rand.Reader, 1024);

현재 암호 작성법 지침에 따르면 RSA 알고리즘과 함께 적어도 2048비트의 키 길이를 사용해야 합니다. 하지만 계산 기능과 인수 분해 기술[1]이 지속적으로 발전하기 때문에 나중에는 권장되는 키 크기가 분명 더 커질 것입니다.

예제 1: 다음 코드는 512비트 RSA 암호화 키를 생성합니다.

public static KeyPair getRSAKey() throws NoSuchAlgorithmException {
KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA");
keyGen.initialize(512);

KeyPair key = keyGen.generateKeyPair();
return key;
}


대칭 암호화의 경우 키 길이가 적어도 128비트여야 합니다.

Abstract
불충분한 키 크기를 사용하면 강력한 암호화 알고리즘이더라도 무차별 대입 공격에 크게 취약해질 수 있습니다.
Explanation
현재 암호 작성법 지침에 따르면 RSA 알고리즘과 함께 적어도 2048비트의 키 길이를 사용해야 합니다. 하지만 계산 기능과 인수 분해 기술[1]이 지속적으로 발전하기 때문에 나중에는 권장되는 키 크기가 분명 더 커질 것입니다.

예제 1: 다음 코드는 1024비트 RSA 암호화 키를 생성합니다.

...
$keysize = 1024;
$options = array('private_key_bits' => $keysize, 'private_key_type' => OPENSSL_KEYTYPE_RSA);
$res = openssl_pkey_new($options);
...


대칭 암호화의 경우 키 길이는 168비트(Triple DES) 및 128비트(AES) 이상이어야 합니다.

Abstract
불충분한 키 크기를 사용하면 강력한 암호화 알고리즘이더라도 무차별 대입 공격에 크게 취약해질 수 있습니다.
Explanation
현재 암호 작성법 지침에 따르면 RSA 알고리즘과 함께 적어도 2048비트의 키 길이를 사용해야 합니다. 하지만 계산 기능과 인수 분해 기술[1]이 지속적으로 발전하기 때문에 나중에는 권장되는 키 크기가 분명 더 커질 것입니다. 대칭 암호화의 경우 키 길이가 적어도 128비트여야 합니다.

예제 1: 다음 코드는 약한 암호화 알고리즘과 불충분한 키 크기를 사용합니다.

let iv = getTrueRandomIV()
...
let cStatus = CCCrypt(UInt32(kCCEncrypt),
UInt32(kCCAlgorithmDES),
UInt32(kCCOptionPKCS7Padding),

UInt32(kCCKeySizeDES), // 64-bit key size
iv,
