What is ADFS SAML?

ADFS SAML is Active Directory Assembly Services – Security Assertion Markup Language is a software component developed by Microsoft that can be installed on Windows Server operating systems to give users access to integrated access to existing systems and applications across organizational boundaries. The claim-based access control license model is used to maintain application security and implement United Identity.

Authentication-based authentication is the user authentication process based on a series of claims about their identity contained in trusted code. In ADFS SAML, a federation is formed between two organizations by building trust between two security domains. Federation servers document one side (account side) used by standard tools in Active Directory domain services and issue tokens that contain a series of claims about users, including their identities.

On the other hand, the resource side, another federation server, validates the token and issues another token for the local server to accept the claimed identity. This system allows access to resources or services to users included in other security domains without encouraging users to authenticate directly to the system and without two systems that share a database of user identities or passwords.

Active Directory Federation (ADFS) service is a Single Entry System (SSO) solution created by Microsoft. As a component of the Windows Server operating system, this gives users reliable access to applications that cannot use Windows Integrated (IWA) through Active Directory (AD). ADFS SAML was developed to provide flexibility, giving organizations the ability to control their employee accounts while simplifying user experience: Employees only need to remember a set of credentials to access various applications via ADFS SAML SSO.

ADFS manages authentication through hosted proxy services between the AD and the target application. He uses the Unified Trust Fund, which binds ADFS and target applications to provide access to users. This allows users to log in to applications that are consolidated through SSO without having to authenticate themselves when they apply directly.

The authentication for ADFS SAML process generally follows the following four steps:

  • The user moves to the URL provided by the ADFS service.
  • The ADFS service then authenticates the user through the organization’s AD service.
  • When confirmed, the ADFS service then asks the user to authenticate.
  • The user’s browser then redirects this claim to the target application, which gives or rejects access based on the Federated Trust service that was created.

ADFS produces the need to overcome the authentication challenges made by M in an increasingly online world. AD and IWA have set limits on modern documentation, and cannot authenticate users to access AD applications that are externally integrated. This is a challenge in the modern workplace, where users often need access to applications that are not owned or managed by their AD organization. ADFS is able to resolve and simplify these third-party authentication challenges, but is accompanied by several risks and disadvantages.

ADFS solves problems for users who need access to integrated AD applications while working remotely, and offer flexible solutions to authenticate their standard organizational credentials through the Web interface. Allows users from one organization to access other organized applications outside their domain. Examples include applications in partner organizations or cloud services that are now part of the IT landscape that is expanded in many organizations.

More than 90% of organizations use Active Directory, which means many also use ADFS. ADFS has disadvantages, making it far from the ideal authentication solution. This includes hidden infrastructure defects and maintenance costs, as well as security risks. Although ADFS is a free feature on Windows Server, ADFS requires a Windows Server license and a host to accommodate ADFS services, which are subject to company fees.

Server license fees have increased since the release of Windows Server 2016, with the current license being approved primarily. In addition to the direct costs of commissioning ADFS, organizations also need to consider ongoing operational costs to manage and maintain ADFS services. Licenses between AD domains must be maintained by staff with deep technical skills and ADFS servers need to be regularly repaired, updated and supported. In addition, because ADFS is an important service, high availability is the key.

Depending on how it is configured, ADFS can be worth more than expected: both directly because more infrastructure is needed, and indirectly with increasing complexity. Assignment, configuration, and maintenance of ADFS solutions is not an easy task. In addition, every time an application is added to the ADFS service, the process takes a long time and is technically complicated, which inhibits information technology flexibility. The standard ADFS installation is not as safe as possible. To secure it properly, there are many steps that need to be done. In addition, while ADFS works on Windows Server, it must also be stronger and safer to ensure that the solution is not risky in adfs saml.
