访问修饰符的安全影响（公共，私有，内部，受保护） [英] Security impact of access modifiers (public, private, internal, protected)

问题描述

实际使用C＃，Java和其他编程语言中的类，属性或方法的访问修饰符对应用程序的安全性有影响吗？他们是否也以某种方式防止未经授权的访问？或者它们只是清晰和适当编程的工具？

Do the access modifiers of classes, properties or methods in C#, Java and other programming languages actually have an impact on the security of an application? Do they also protect against unauthorized access in some way? Or are they just a tool for clear and propper programming?

推荐答案

不，访问修饰符不提供安全保护。它们仅仅是为了方便开发人员，例如它们有助于强制执行良好的编码实践并帮助编写模式。

No, access modifiers don't offer security protection. They are merely there for developer convenience, e.g. they help to enforce good coding practices and help with programming patterns.

通过使用Java / C＃和其他语言中的反射，可以轻松访问其他无法访问的修饰符。

It's easy to access otherwise inaccessible modifiers by using reflection in Java/C# and other languages.
