🔑 What is Identity and Access Management (IAM)? Identity and Access Management (IAM) is a framework of policies and technologies that ensures the right individuals have the appropriate access to technology resources. IAM systems are essential for organizations to securely manage digital identities, control access to applications, and ensure data security. With the increasing number of cyber threats, IAM is becoming a crucial component of any organization’s security infrastructure. 🔧 Why IAM Matters? In today’s interconnected world, organizations face the challenge of managing numerous users, devices, and applications. IAM provides a centralized way to manage access controls across all these systems, ensuring that only authorized individuals can access sensitive data or perform critical actions. ...

Security Assertion Markup Language (SAML) is an XML-based open standard used for exchanging authentication and authorization data between different security domains. SAML is most commonly used in Single Sign-On (SSO) scenarios, allowing users to access multiple applications or services without the need to log in repeatedly. It has become a critical technology for enabling secure identity management across web-based applications, particularly in enterprise environments and cloud services. What Are Identity Providers (IdP) and Service Providers (SP)? In the context of SAML, there are two primary roles: ...

OAuth 2.0 is a widely used authorization framework that enables applications to access user data on behalf of the user without requiring the user to share their credentials. It provides a secure and standardized approach to delegating access control, ensuring that applications can interact with various services while keeping user information private. The Authorization Code Flow is one of the core grant types in OAuth 2.0, designed for scenarios where both the client and the authorization server need to exchange information securely. ...

OAuth 2.0 is a widely used authorization framework that allows applications to obtain limited access to user resources without handling user credentials directly. The Authorization Code Flow with PKCE (Proof Key for Code Exchange) is a security-enhanced version of the Authorization Code Flow, specifically designed to address vulnerabilities in public clients like mobile apps and single-page applications (SPAs) that cannot safely store a client secret. Why PKCE Is Needed Traditional Authorization Code Flow relies on a client_secret to authenticate the client when exchanging an authorization code for a token. In public clients (like browser apps or mobile apps), this secret cannot be safely stored. Without proper safeguards, attackers could intercept the authorization code during redirection and exchange it for tokens. ...

Security Assertion Markup Language (SAML) is a robust open standard that enables the exchange of authentication and authorization data between different security domains. It is most commonly used in Single Sign-On (SSO) scenarios, allowing users to access multiple applications with a single login. To effectively implement and manage secure SSO systems, it’s essential to understand the fundamental components of SAML: Assertion, Binding, Protocol, and Metadata. 1. Assertion The Assertion is the core element of the SAML protocol. It represents a statement made by the Identity Provider (IdP) about a subject, usually the user, and contains authentication and authorization information. This information is passed to the Service Provider (SP), which uses it to grant or deny access to the requested resources. There are three main types of assertions: ...

OAuth 2.0 is a widely used authorization framework that enables applications to obtain limited access to user accounts on an HTTP service. Among its several grant types, the Client Credentials Flow is uniquely designed for machine-to-machine (M2M) communication where no user is involved. What is the Client Credentials Flow? The Client Credentials Flow is used when applications (typically backend services, daemons, or microservices) need to access resources or APIs on their own behalf, rather than on behalf of a user. This flow is ideal for internal services, automation scripts, or server-to-server communication where the resource owner is the application itself. ...

SAML (Security Assertion Markup Language) is a widely adopted standard for Single Sign-On (SSO) in enterprise identity federation. Just as SAML SSO simplifies user authentication across multiple systems, SAML Single Logout (SLO) provides a standardized way to terminate sessions across those same systems. Let’s explore how it works and the critical differences between redirect vs POST bindings, SP-initiated vs IdP-initiated logout, and the essential role of the Session Index. 🔐 What is SAML Single Logout (SLO)? SAML Single Logout (SLO) allows a user to log out from one application (Service Provider, or SP) and have that logout propagated to all other applications that the user has accessed during their session. This prevents “orphaned sessions” and ensures consistent security behavior across systems. ...
