ASP.NET Core提供了几种方式来保护应用程序免受凭据填充攻击。以下是一些常见的解决方法和代码示例:
[HttpPost]
[ValidateAntiForgeryToken]
public IActionResult Login(LoginViewModel model)
{
// 验证AntiForgeryToken
if (!ModelState.IsValid)
{
// 处理登录逻辑
}
// ...
}
public class UserService
{
private readonly PasswordHasher _passwordHasher;
public UserService()
{
_passwordHasher = new PasswordHasher();
}
public bool ValidatePassword(User user, string password)
{
var result = _passwordHasher.VerifyHashedPassword(user, user.PasswordHash, password);
return result == PasswordVerificationResult.Success;
}
}
public void ConfigureServices(IServiceCollection services)
{
// 添加身份验证服务
services.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
options.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = CookieAuthenticationDefaults.AuthenticationScheme;
})
.AddCookie(options =>
{
options.Cookie.Name = "YourCookieName";
options.Cookie.SameSite = SameSiteMode.Strict;
options.Cookie.SecurePolicy = CookieSecurePolicy.Always;
options.Cookie.HttpOnly = true;
options.LoginPath = "/Account/Login";
options.LogoutPath = "/Account/Logout";
});
// 添加授权服务
services.AddAuthorization(options =>
{
options.AddPolicy("AdminOnly", policy => policy.RequireRole("Admin"));
});
// ...
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
// 使用身份验证中间件
app.UseAuthentication();
// 使用授权中间件
app.UseAuthorization();
// ...
}
以上是几种常见的保护ASP.NET Core免受凭据填充攻击的解决方法和代码示例。根据应用程序的具体需求,可能需要采用其他防护措施来提高安全性。
