The Relevance Of SAML Authentication

Cloud access management is a primary challenge of using cloud apps safely in business environments is. With the proliferation of SaaS, PaaS, and IaaS, managing access policies, including strong authentication, for each app creates a burden on the IT team. Users need to keep several sets of usernames and passwords, resulting in lost or forgotten passwords, lost productivity, and 'password fatigue.' In reality, 20 percent of help desk tickets account for lost or forgotten passwords.

Besides, IT also lacks visibility into which users access which applications and how often, resulting in shadow IT and resource mismanagement. The lack of robust user access control leads to vulnerability to compromise through brute force, phishing, hacking of cloud databases, and other threat vectors.

Without centrally managed access controls, it is not feasible to effectively scale the usage of cloud apps within an enterprise, resulting in safety gaps, high administration overhead, user dissatisfaction, and operational inefficiencies. With identification being the new safety perimeter, specifications ...
... must be established for the underlying technologies for that perimeter.

SAML Authentication

SAML or Security Assertion Markup Language is a widely-used open XML-based standard for the exchange, between parties, of authentication and authorization data. Using only one username and password set, the SAML protocol allows users to log into their cloud apps. This is called an identity federation since users only need to retain a single identity instead of having multiple usernames or identities. A trusted single SAML-supporting system called an identity provider (IdP) with identity federation regulates user authentication, with cloud apps delegating the authentication process to the identity provider any time a user tries to access them.

SAML-Based Identity Federation

Federated identity solves the difficulties and frustrations, whether internal or external to an enterprise, of handling credentials for multiple web apps separately. Standards allow federated identity, and SAML is a key piece of the architecture of the federation, as well as the norm of the predominant identity federation. In addition, widespread and increasing acceptance is a key benefit of SAML.

SAML is a very versatile standard since it is XML-based. Single Sign-On (SSO) connections with several different federation members can be facilitated by a single SAML implementation. With interoperability, SAML has an advantage over the proprietary SSO mechanism.

How SAML Authentication Works

Authentication by SAML allows identity information to be exchanged between an IdP and cloud or web applications. A SAML-based authentication model consists of an identity provider that is a 'SAML assertions' creator and a service provider that is an assertion user and other SAML-supporting cloud apps. In general, SAML assertions are signed with a PKI signature that confirms the assertion is authentic.

An authentication service operating as an identity provider collects the credentials of the user and returns a response to the accessed cloud app. This response is called a SAML assertion. An accept or reject response is present in the SAML assertion. The user will be signed in if the SAML statement is correct. Mapping users between the IdP and the service provider is the key to allowing SAML-based identity federations.

Identity Federation For Central Management Of User Access Control

SAML can be used to expand the enterprise identity of existing users to cloud applications. Federated authentication entirely removes the need to remember different usernames and passwords. Throughout all their cloud applications, users log in with the same business identity, the same identity they use to log in to the corporate network.

SAML-based identity federation is, from a user's perspective, seamless. SAML uses a cookie, so if you open other cloud apps on a new tab, such as Dropbox, WordPress, Salesforce, etc., a user who is logged into Office 365 would not need to re-authenticate.

SAML-Based Identity Federation Benefits

SAML authentication allows IT administrators to handle a single credential set per account for all applications. It also eliminates password fatigue of users. IT must revoke only one credential set when users leave the organization. Without signing in to each distinct cloud app, credentials can be revoked. Automated workflows will further reduce the overhead of lifecycle administration.
