To Wrap It Up

The engineers would be aware of how difficult it is to manage and regulate user and access management in SaaS applications. Defining user roles and permissions based on their accessibility, subscriptions, and organizational structure can essentially affect your product scalability and experience if not done correctly.

Hey there! This blog is almost about 1500+ words long & not everyone likes to read that much. We understand that.

This is precisely why we made a podcast on the topic. Hamir Nandaniya, VP of Engineering at Maruti Techlabs, talks to Bikshita Bhattacharyya about using an Identity Server to centralize your application’s access management & user authentication.

He also talks about what his client was using before Identity Server & the need to switch to an identity server. The talk also focuses on the challenges faced during the implementation, its working, benefits, and more! Here is a small snippet from that episode. Check it out!

An efficient means of user management is through centralized authorization. And that is where IdentityServer comes into the picture. IdentityServer is an authentication server designed to provide a common way to authenticate requests to all of your applications, regardless of whether they’re web, native, mobile, or API endpoints.

Identity Server acts as a central database that stores user’s credentials. The identity server is checked to authenticate user access as it is a core part of any identity and access control infrastructure. In a nutshell, an identity server is a piece of software that issues security tokens to clients.

In a typical company, numerous routine informational transactions occur every day. These include yet are not restricted to online invoices, product catalogue, new recruitment information, salary details, etc. For each of these informational transactions, the company must determine who is allowed to view its data. Information relating to accounting and human resources must be restricted to employee use only.

Common Web App Scenarios

Usually, applications need to support the following scenarios:

  • Users accessing web applications via a browser.
  • Users accessing back-end Web APIs from program-based apps.
  • Users accessing back-end Web APIs via mobile or native clients.
  • Other applications accessing back-end Web APIs (without a functioning client or UI).
  • Any application may need to communicate with other Web APIs, using its own identity or assigning to the user’s identity.

Typically, every layer of the physical infrastructure(front-end, middle-tier, and back-end) protects identity data and APIs. Furthermore, it has to implement authentication and user authorization – often against the same user store.

Outsourcing these fundamental security functions to an identity provider prevents copying that functionality across those applications and endpoints.

What Are The Security Concerns?

Security concerns are divided into two parts : 

  • Authentication

Authentication is necessary when an application needs to know the identification of the current user. Typically these applications handle data on behalf of that user. They need to make sure that this user can only access the data for which he/she is permitted. The most common example of that is (classic) web applications.

The most well-known authentication protocols are SAML2p, WS-Federation and OpenID Connect – SAML2p being the most famous and the most widely used.

OpenID Connect is the latest of the three protocols however is viewed as the future since it has the maximum potential for contemporary applications. It was designed for mobile application scenarios right from the start and is created to be API-friendly.

  • API Access

Applications have two primary approaches to communicate with APIs – using the application identity, or allocating the user’s identity. 

OAuth2 is a convention that permits applications to request access tokens from a security token service and utilize them to communicate with APIs. This delegation reduces intricacy in both the client applications and the APIs since confirmation and approval can be at the centre stage.

OpenID Connect and OAuth 2.0 

OpenID Connect and OAuth 2.0 are very alike – in fact, OpenID Connect is an extension of OAuth 2.0. The two primary security challenges, API access and authentication, are wrapped into a single protocol. This protocol often takes a single round trip to the security token service.

The association of OpenID Connect and OAuth 2.0 is the best approach to secure modern applications for years to come. IdentityServer4 is an implementation of these two conventions and is highly optimized to tackle the run of the mill security issues of today’s mobile, native and web applications.

Why Do We Need An Identity Server?

Many organizations permit access to information on a per-application footing. For example, an employee may be required to set up a username and password to access the company’s health benefits and a separate username and password to access the HR department’s online forms.

An administrator deciphers the organization’s user’s input into a data format that the service can perceive for each website or service. Each service added to the company must be planned and maintained independently.

A company has to store and access multiple types of information through its enterprise. Similarly, various enterprise users must use that information to run smoothly for the company’s business. This is where Identity Server and identity service provider come to the rescue.

How Does An Identity Server Help?

Identity Server reduces managerial costs and eliminates the unnecessary user information associated with per-application solutions. Identity Server creates a sole record entry for every enterprise user.

It allows an administrator to assign specific rules or approaches overseeing which information or services each user can access. Identity Server enables a user to access multiple resources within the organization significant with just one single identity.

Identity Server can be utilized to verify actual users through sign-in forms and service-based verification. The latter typically involves token issuance, validation, and renewal without any UI. IdentityServer is designed to be an adaptable solution. Each case is mainly customized to suit an individual organization and set of applications’ needs.

How Does An Identity Server Work?

When a company user or an external application tries to access information stored on a company’s web server, the API gateway intercepts the request and directs it to Identity Server. Identity Server asks for the user credentials – a username and password.

If the credentials match those stored in the central Directory Server, the Identity Server validates that the user is who he claims to be. Furthermore, the Server assesses the rules in line with the user’s identity. It then determines whether the user is allowed to view the requested information or not.

At last, the Identity Server either grants or denies the user access to the information.

The image above illustrates how Identity Server intercepts requests from users before allowing or denying access.

Identity Server combines four significant features into a single product that can be viewed in a single administration console:

  • Identity Administration
  • Access Management
  • Service Management
  • Federation Management

    1. Identity Administration

Identity Server provides an identity structure for creating and overseeing directory objects such as organizations, groups, roles, and user IDs.

    2. Access Management

Access management feature makes it possible to verify whether a user is who he says he is. The user is authorized to access application servers used within the organization.

    3. Service Management

Identity Server provides a service management SDK that developers can use to register and unregister services. It also helps to manage schema and configuration information. 

    4. Federation Management

Identity federation allows an individual to log in at one service provider’s site and move to an affiliated service provider site without re-authenticating or re-establishing organizations.

Do you wonder how Identity Server addressed our client’s user management woes? Hamir Nandaniya does a deep dive on how adopting Identity Server and Access Management can benefit your organization and clients with improved user experience, regulatory compliances, and security issues.. Take a look at the video below 👇

Benefits of Using Identity Server

There are many benefits of using an Identity server, especially when anyone has a suite of products like GSuite and wants to implement authentication and authorization in API(s) out of the box.

  • Centralised user management – Implementation of identity server reduces operational complexities and ensures centralised user management.
  • Enhanced user experience with easy logins – A single identity to log in to multiple different systems. Facilitates SSO between multiple logged-in applications for an improved user experience. It also enables passwordless authentication for quick and user-friendly access.
  • Identity federation – Enables federated access to the web and mobile applications across multiple trust domains using open identity standards.
  • Multi-factor and adaptive authentication – Multi-factor and adaptive authentication based on context, risk, and identity attributes.
  • Privacy and consent management – It gives users control over their data.Record, review, and revoke user consent. 
  • API security – Secure access to APIs and microservices based on open standards such as OAuth.

Other benefits include increased business agility, organization management, regulatory compliance and security best practices.
