Identity and Access Management (IAM) comprises a combination of policies, procedures, and technological tools designed to oversee digital identities and control their access to specific IT resources.

In software development and information technology, IAM manages who can access resources within a system, application, or network at the right times.

Identity and Access Management solutions are crucial for preventing unauthorized access and breaches, ensuring regulatory compliance for data protection, increasing operational efficiency, and providing a simplified user experience.

• Enhanced Security –reduce password breaches and security incidents
• Reduced Administrative Overhead
• Improved User Experience—users only must authenticate once
• Efficient Session Management—simplifies management of user accounts and user permissions.
• Streamlined Compliance

IAM might involve integrating authentication mechanisms (like OAuth), setting up role-based access controls in applications, or using dedicated IAM platforms or services that handle the intricacies of identity verification, policy enforcement, and audit trails.

• Identity: The identity is a unique representation of a user (or entity) within a system. This can be an employee, customer, partner, or even a machine or service account. Each identity will typically have associated attributes, such as a username, email, roles, etc.

• Authentication: This is the process of verifying the identity’s authenticity and necessary permissions to access resources. Typically, this involves using credentials like a username/password, tokens, biometrics, or a multi-factor authentication (MFA) mechanism.

• Access: Refers to the permission or capability of an authenticated identity to perform specific actions on certain resources. For instance, a user might have read, write, or delete access in a file system. Access Management involves the authorization or revoking based on roles and permissions.

• Authorization: Once an identity is authenticated, the next step is determining what they can do. This is handled by the authorization process, which checks permissions and grants access based on predefined policies.

• Management: Management involves the procedures and tools necessary to monitor and regulate access to specific resources. This includes identity lifecycle management tasks such as onboarding, updating roles or permissions, offboarding users, and auditing (detecting suspicious activities and identifying potential breaches).

Single Sign-On (SSO) feature within Identity and Access Management (IAM) allows users to authenticate once and access multiple applications, systems, or services without separate logins.

It emphasizes secure access to servers, applications, and databases through a unified portal. SSO streamlines the user experience by centralizing authentication servers and eliminating the need for repeated logins.

This approach enhances convenience and security, safeguarding access to crucial data and applications. Additionally, SSO integrates login capabilities, connecting users seamlessly to vital business applications.

1. Initial Authentication: The user logs into an SSO-enabled environment for the first time, typically by entering their credentials (like a username and password) or through another authentication method.

2. Authentication Token: Once authenticated, the system issues the user an authentication token or session cookie.

3. Token Verification: As the user tries to access other SSO-enabled applications or services, the system checks the validity of the authentication token instead of asking for credentials again.

4. Access Granted: If the token is valid and the user has permission, access is granted without needing another login.

Access tokens can have a short lifespan for security reasons. If someone manages to intercept or steal an access token, it will only be valid for a limited time. Once the access token expires, a refresh token can be used to obtain a new one without the user needing to re-enter their credentials.

Refresh Tokens are used as a layered defense strategy. They are used in authentication systems to obtain a new access token without requiring users to re-authenticate again.

By using refresh tokens, the access token is renewed in the background. A refresh token also adds security as it can be configured to be used once and becomes invalidated.

Using the refreshed token to get a new access token can provide an opportunity to re-evaluate the context and check changes in security parameters before issuing the new access token.

• User: The individual trying to access an SSO-protected application or service.

• User Agent: Usually a web browser, mobile app, or other client-side application used by the user.

• Service Provider (SP): An application or system the user wants to access. The SP relies on the Identity Provider to authenticate users.

• Identity Provider (IdP): A trusted system that authenticates users. After authenticating a user, the IdP provides a token or assertion, vouching for the user’s identity to the Service Providers.

• Centralized Authentication Server: In some architectures, this is the component where the user’s credentials are checked. It can be part of the IdP or a separate component that the IdP communicates with.

• Directory Service: This is a database of user credentials and attributes, often used by the centralized authentication server to verify user credentials. Examples include LDAP, Active Directory, etc.

• Assertion: a package of information that supplies statements made by an identity provider (IdP) about an authentication event, user attributes (username, roles, email), or entitlements (permissions). The assertion serves as proof of a user’s identity and other attributes. When the user tries to access a service, the service provider checks the assertion, verifies its validity and the claims within, and grants/denies access based on the information provided.

• OpenID Connect (OIDC): OIDC is an identity layer built on the OAuth 2.0 protocol. It uses JWTs for its ID tokens, which provide information about the authenticated user.

• Security Assertion Markup Language (SAML): SAML uses XML-based assertions for conveying authentication and authorization information.

• OAuth/OAuth 2.0 (Open Authorization): OAuth 2.0 is a framework for authorization and doesn’t mandate using JWTs. However, JWTs can be used as access tokens within the OAuth 2.0 framework, especially in “Bearer Token” usage.

• Lightweight Directory Access Protocol (LDAP): LDAP is a protocol for accessing and managing directory services. Its format is not applicable in the traditional sense of tokens or assertions. Instead of assertions, it deals with data structures like entries, attributes, and distinguished names. It does not use JWTs.

• Open-Source Nature: The open-source model allows organizations to deploy an extensive IAM solution without incurring licensing fees, offering transparency and the flexibility to modify the software based on specific needs.

• Configuration and Integration: Keycloak is adaptable and can cater to unique organizational needs. Thanks to its support for OpenID Connect (OIDC) and SAML 2.0, it seamlessly integrates with many applications and systems.

What is an NPM Module?

npm stands for “Node Package Manager.” In the context of Node.js and its ecosystem, an NPM module is a set of reusable JavaScript functions or code bundled together, which can be imported and used in other projects. These modules provide a way to structure and reuse code across different application parts or multiple projects.

Each module typically has its context and does not interfere with other modules; they can be local to a specific project or published to the npm registry, making them available to the broader community. Also, a module can depend on other modules. All its dependencies are automatically installed when a module is installed using npm. 

In essence, when developers talk about an “npm module,” they’re referring to a set of JavaScript functionality packaged to make it easy to import and use in a Node.js application. This packaging allows for better code organization, reuse, and distribution.

npm Package Registry

The npm Registry is a free platform for JavaScript code sharing, supporting over two million package modules of code and an essential part of the JavaScript community. The platform is owned by npm, Inc. — founded in 2014 and acquired by GitHub in 2020.

IAM Solutions and NPM Modules

Identity Access and Management (IAM) and Single Sign-On (SSO) solutions might interact with NPM modules in various ways, especially in the context of Node.js-based applications or services.

IAM Libraries/Modules:

Some NPM packages offer IAM functionalities, from authentication to authorization. These libraries can be integrated into Node.js applications to manage user identities, roles, permissions, etc.

An NPM package may support numerous strategies, including OAuth, OpenID Connect, SAML, etc. Developers turn to NPM packages or modules tailored for integrating with a Node.JS application.

Some NPM modules contain middleware packages for popular IAM solutions such as Keyclock. These packages are available and simplify adding access and management capabilities to your applications.

NPM, as a platform, also has its own set of AIM functionalities that can manage access to publish or update packages using tokens and roles. These might be used to control access to NPM resources.

Developers must be cautious when selecting npm modules for IAM/SSO to ensure they choose well-maintained, reputable, and secure packages.

An NPM module should be updated, releasing security patches to address vulnerabilities. While IAM and SSO are concepts largely independent of npm, the interaction comes into play when developers seek an open-source NPM package to integrate these functionalities into their Node.js applications.

At Krasamo, we have developed an NPM module that is publicly hosted and can be tailored to integrate with a customized solution, ensuring seamless interaction between a Node.JS application and Keyclock. (AIM System).
