JE.IdentityServer.Security

An OWIN Middleware component for an OpenIdConnect endpoint that provides the following a set of security features

Currently targets IdentityServer3 v2.

TL;DR

Features

A set of OWIN middleware components providing the following features:

• Google Recaptcha for OpenIdConnect

• Throttling for logins

Throttling for OpenIdConnect native logins

In order to register the middleware for throttling, you should register your implementation of ILoginStatistics with your IoC container (see below) and inject this into the middleware as a factory lambda method. Your implementation of ILoginStatistics must implement IDisposable and the lifetime of this object will be managed per OWIN request.

app.UsePerOwinContext<ILoginStatistics>(() => new ImplementationOfLoginStatistics());

app.UseThrottlingForAuthenticationRequests(new IdentityServerThrottlingOptions
{
    ProtectedPath = "/identity/connect/token",
    NumberOfAllowedLoginFailures = 3,
    ExcludedUsernameExpressions = _excludedUsernameExpressions,
    ProtectedGrantTypes = new string[] { "password" },
});

// Register IdentityServer
app.Map("/identity", idsrvApp => idsrvApp.UseIdentityServer(IdentityServerBootstrap.CreateStartupOptions()));

IdentityServerThrottlingOptions is used to configure the middleware on bootstrap and provides the following parameters:

Parameter	Default	Description
ProtectedPath	/identity/connnect/token	Path to protect
NumberOfAllowedLoginFailures	0	Number of allowed login failures before throttling requests
ExcludedUsernameExpressions	empty list	A list of regexes that allows you to skip throttling and reporting for specific email addresses eg load testing accounts
ProtectedGrantTypes	empty list	A list of protected grant types that should be throttled eg native vs social login

Injecting your own services with your favourite container

var middlewareOptions = new IdentityServerThrottlingOptions
{
// some options
};

var container = new MyContainer();  // eg. StructureMap in this case
appBuilder.UsePerOwinContext(() => container.GetInstance<ILoginStatistics>());

appBuilder.UseThrottlingForAuthenticationRequests(middlewareOptions);
