Reino: Security Features

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.

Key Management: Hardcoded Encryption Key

Abstract
Chaves de criptografia embutidas em código podem comprometer a segurança de uma maneira que não é fácil de remediar.
Explanation
Nunca é uma boa ideia inserir uma chave de criptografia em código fixo, pois isso permite que todos os desenvolvedores do projeto a visualizem, além de também dificultar extremamente a correção do problema. Depois que o código está em produção, é necessário um pacote de software para alterar a chave de criptografia. Se a conta protegida pela chave de criptografia for comprometida, os proprietários do sistema deverão escolher entre a segurança e a disponibilidade.

Exemplo 1: O seguinte código usa uma chave de criptografia inserida em código fixo:


...
encryptionKey = "lakdsljkalkjlksdfkl".
...


Qualquer pessoa com acesso ao código tem acesso à chave de criptografia. Depois que o aplicativo for distribuído, não será mais possível alterar a chave de criptografia, a não ser que um patch seja aplicado a esse programa. Um funcionário com acesso a essas informações pode usá-las para invadir o sistema. Se os invasores tivessem acesso ao executável do aplicativo, eles poderiam extrair o valor da chave de criptografia.

Abstract
Chaves de criptografia embutidas em código podem comprometer a segurança de uma maneira que não é fácil de remediar.
Explanation
Nunca codifique uma chave de criptografia porque isso torna a chave de criptografia visível para todos os desenvolvedores do projeto e torna a correção do problema extremamente difícil. Alterar a chave de criptografia após o código estar em produção requer uma correção do software. Se a conta que a chave de criptografia protege for comprometida, o proprietário do sistema deverá escolher entre a segurança e a disponibilidade do sistema.

Exemplo 1: O código a seguir realiza a criptografia AES usando uma chave de criptografia em código fixo:


...
Blob encKey = Blob.valueOf('YELLOW_SUBMARINE');
Blob encrypted = Crypto.encrypt('AES128', encKey, iv, input);
...


Qualquer pessoa com acesso ao código pode ver a chave de criptografia. Depois que o aplicativo for distribuído, não será mais possível alterar a chave de criptografia sem um patch de software. Um funcionário com acesso a essas informações pode usá-las para invadir o sistema. Qualquer invasor com acesso ao executável do aplicativo pode extrair o valor da chave de criptografia.

Abstract
Chaves de criptografia embutidas em código podem comprometer a segurança de uma maneira que não é fácil de remediar.
Explanation
Nunca é uma boa ideia inserir uma chave de criptografia em código fixo. Não apenas a codificação fixa de uma chave de criptografia permite que todos os desenvolvedores do projeto visualizem a chave de criptografia, como também torna a correção do problema extremamente difícil. Depois que o código está em produção, é necessário um pacote de software para alterar a chave de criptografia. Se a conta protegida pela chave de criptografia for comprometida, os proprietários do sistema deverão escolher entre a segurança e a disponibilidade.

Exemplo: O seguinte código usa uma chave de criptografia inserida em código fixo:


...
char encryptionKey[] = "lakdsljkalkjlksdfkl";
...


Qualquer pessoa com acesso ao código tem acesso à chave de criptografia. Depois que o programa for distribuído, não será mais possível alterar a chave de criptografia, a não ser que um patch seja aplicado a esse programa. Um funcionário com acesso a essas informações pode usá-las para invadir o sistema. Se os invasores tiverem acesso ao executável do aplicativo, eles poderão desmontar o código, que conterá o valor da chave de criptografia utilizada.

Abstract
Chaves de criptografia embutidas em código podem comprometer a segurança de uma maneira que não é fácil de remediar.
Explanation
Nunca é uma boa ideia inserir uma chave de criptografia em código fixo, pois isso permite que todos os desenvolvedores do projeto a visualizem, além de também dificultar extremamente a correção do problema. Depois que o código está em produção, é necessário um pacote de software para alterar a chave de criptografia. Se a conta protegida pela chave de criptografia for comprometida, os proprietários do sistema deverão escolher entre a segurança e a disponibilidade.

Exemplo 1: O seguinte código usa uma chave de criptografia inserida em código fixo:


...
private static final String encryptionKey = "lakdsljkalkjlksdfkl";
byte[] keyBytes = encryptionKey.getBytes();
SecretKeySpec key = new SecretKeySpec(keyBytes, "AES");
Cipher encryptCipher = Cipher.getInstance("AES");
encryptCipher.init(Cipher.ENCRYPT_MODE, key);
...


Qualquer pessoa com acesso ao código tem acesso à chave de criptografia. Depois que o aplicativo for distribuído, não será mais possível alterar a chave de criptografia, a não ser que um patch seja aplicado a esse programa. Um funcionário com acesso a essas informações pode usá-las para invadir o sistema. Se os invasores tivessem acesso ao executável do aplicativo, eles poderiam extrair o valor da chave de criptografia.

Abstract
Senhas com codificação rígida podem comprometer a segurança do sistema de uma maneira difícil de remediar.
Explanation
Jamais use codificação rígida para senhas. Além de expor a senha a todos os desenvolvedores do projeto, isso dificulta consideravelmente a correção do problema. Quando o código estiver em produção, um patch provavelmente será a única forma de alterar a senha. Se a conta que a senha protege for comprometida, os proprietários do sistema deverão escolher entre segurança e disponibilidade.
Exemplo: O seguinte JSON usa uma senha com codificação rígida:


...
{
"username":"scott"
"password":"tiger"
}
...


Essa configuração pode ser válida, mas qualquer usuário que tiver acesso a ela também terá acesso à senha. Depois de o programa ser publicado, alterar a senha “tiger” da conta do usuário “scott” será difícil. Qualquer pessoa que tenha acesso a essa informação poderá usá-la para invadir o sistema.

Abstract
Chaves de criptografia embutidas em código podem comprometer a segurança de uma maneira que não é fácil de remediar.
Explanation
Nunca é uma boa ideia inserir uma chave de criptografia em código fixo, pois isso permite que todos os desenvolvedores do projeto a visualizem, além de também dificultar extremamente a correção do problema. Depois que o código está em produção, é necessário um pacote de software para alterar a chave de criptografia. Se a conta protegida pela chave de criptografia for comprometida, os proprietários do sistema deverão escolher entre a segurança e a disponibilidade.

Exemplo 1: O seguinte código usa uma chave de criptografia inserida em código fixo:


...
NSString encryptionKey = "lakdsljkalkjlksdfkl";
...


Qualquer pessoa com acesso ao código tem acesso à chave de criptografia. Depois que o aplicativo for distribuído, não será mais possível alterar a chave de criptografia, a não ser que um patch seja aplicado a esse programa. Um funcionário com acesso a essas informações pode usá-las para invadir o sistema. Se os invasores tivessem acesso ao executável do aplicativo, eles poderiam extrair o valor da chave de criptografia.

Abstract
Chaves de criptografia HMAC embutidas em código podem comprometer a segurança do sistema de uma maneira difícil de remediar.
Explanation
Nunca é uma boa ideia inserir uma chave de criptografia em código fixo. Não apenas a codificação fixa de uma chave de criptografia permite que todos os desenvolvedores do projeto visualizem a chave de criptografia, como também torna a correção do problema extremamente difícil. Depois que o código está em produção, é necessário um pacote de software para alterar a chave de criptografia. Se a conta protegida pela chave de criptografia for comprometida, os proprietários do sistema deverão escolher entre a segurança e a disponibilidade.
Exemplo 1: O seguinte código usa uma chave de criptografia inserida em código fixo:


require 'openssl'
...
encryption_key = 'hardcoded_encryption_key'
...
cipher = OpenSSL::Cipher::AES.new(256, 'GCM')
cipher.encrypt
...
cipher.key=encryption_key
...


Esse código será executado com êxito, mas qualquer pessoa que tenha acesso a ele terá acesso à chave de criptografia. Depois que o programa é distribuído, provavelmente não há como alterar a chave de criptografia inserida em código fixo "hardcoded_encryption_key", a não ser que um patch seja aplicado ao programa. Um funcionário desonesto com acesso a essas informações pode usá-las para comprometer dados criptografados pelo sistema.

Abstract
Chaves de criptografia embutidas em código podem comprometer a segurança de uma maneira que não é fácil de remediar.
Explanation
Nunca codifique uma chave de criptografia porque isso torna a chave de criptografia visível para todos os desenvolvedores do projeto e torna a correção do problema extremamente difícil. Alterar a chave de criptografia após o código estar em produção requer uma correção do software. Se a conta que a chave de criptografia protege for comprometida, o proprietário do sistema deverá escolher entre a segurança e a disponibilidade do sistema.

Exemplo 1: O exemplo a seguir mostra uma chave de criptografia em um arquivo .pem:


...
-----BEGIN RSA PRIVATE KEY-----
MIICXwIBAAKBgQCtVacMo+w+TFOm0p8MlBWvwXtVRpF28V+o0RNPx5x/1TJTlKEl
...
DiJPJY2LNBQ7jS685mb6650JdvH8uQl6oeJ/aUmq63o2zOw=
-----END RSA PRIVATE KEY-----
...


Qualquer pessoa com acesso ao código pode ver a chave de criptografia. Depois que o aplicativo for distribuído, não será mais possível alterar a chave de criptografia, a não ser que um patch seja aplicado ao programa. Um funcionário com acesso a essas informações pode usá-las para invadir o sistema. Qualquer invasor com acesso ao executável do aplicativo pode extrair o valor da chave de criptografia.

Abstract
Chaves de criptografia embutidas em código podem comprometer a segurança de uma maneira que não é fácil de remediar.
Explanation
Nunca é uma boa ideia inserir uma chave de criptografia em código fixo, pois isso permite que todos os desenvolvedores do projeto a visualizem, além de também dificultar extremamente a correção do problema. Depois que o código está em produção, é necessário um pacote de software para alterar a chave de criptografia. Se a conta protegida pela chave de criptografia for comprometida, os proprietários do sistema deverão escolher entre a segurança e a disponibilidade.

Exemplo 1: O seguinte código usa uma chave de criptografia inserida em código fixo:


...
Dim encryptionKey As String
Set encryptionKey = "lakdsljkalkjlksdfkl"
Dim AES As New System.Security.Cryptography.RijndaelManaged
On Error GoTo ErrorHandler
AES.Key = System.Text.Encoding.ASCII.GetBytes(encryptionKey)
...
Exit Sub
...


Qualquer pessoa com acesso ao código tem acesso à chave de criptografia. Depois que o aplicativo for distribuído, não será mais possível alterar a chave de criptografia, a não ser que um patch seja aplicado a esse programa. Um funcionário com acesso a essas informações pode usá-las para invadir o sistema. Se os invasores tivessem acesso ao executável do aplicativo, eles poderiam extrair o valor da chave de criptografia.
