界: Encapsulation
封装即绘制强边界。在 Web 浏览器中,这可能意味着确保您的移动代码不会被其他移动代码滥用。在服务器上,这可能意味着区分已验证数据和未验证数据、区分一个用户的数据和另一个用户的数据,或者区分允许用户查看的数据和不允许用户查看的数据。
Biometric Authentication: Insufficient Touch ID Protection
Abstract
该应用程序使用 Touch ID 在密钥链中存储了一个项目,但未能将有效指纹限制为存储密钥链项目时可用的指纹。
Explanation
基于 Touch ID 的身份验证可以使用密钥链服务实现,即在密钥链中存储项目,并设置一项访问控制来要求用户需在日后使用其指纹检索该项目。以下策略可用于定义如何使用其指纹对用户进行验证:
-
-
-
使用 Touch ID 时,应使用
示例 1:以下代码使用
-
kSecAccessControlUserPresence
:限制为通过 Touch ID 或密码访问。不要求 Touch ID 可用或已注册。添加或删除指纹后,仍可通过 Touch ID 访问项目。-
kSecAccessControlTouchIDAny
:限制为通过 Touch ID 使用任何已注册的指纹访问。添加或删除指纹后,项目不会失效。-
kSecAccessControlTouchIDCurrentSet
:限制为通过 Touch ID 使用当前已注册的指纹访问。添加或删除指纹后,项目将会失效。使用 Touch ID 时,应使用
kSecAccessControlTouchIDCurrentSet
属性阻止以后添加指纹或删除现有指纹。示例 1:以下代码使用
kSecAccessControlTouchIDAny
限制,该项限制允许任何以后注册的指纹对密钥链项目解除锁定:
...
SecAccessControlRef sacRef = SecAccessControlCreateWithFlags(kCFAllocatorDefault,
kSecAttrAccessibleWhenPasscodeSetThisDeviceOnly,
kSecAccessControlTouchIDCurrentSet,
nil);
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
[dict setObject:(__bridge id)kSecClassGenericPassword forKey:(__bridge id) kSecClass];
[dict setObject:account forKey:(__bridge id)kSecAttrAccount];
[dict setObject:service forKey:(__bridge id) kSecAttrService];
[dict setObject:token forKey:(__bridge id)kSecValueData];
...
[dict setObject:sacRef forKey:(__bridge id)kSecAttrAccessControl];
[dict setObject:@"Please authenticate using the Touch ID sensor." forKey:(__bridge id)kSecUseOperationPrompt];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
OSStatus status = SecItemAdd((__bridge CFDictionaryRef)dict, nil);
});
