What is Security Access Markup Language (SAML)?
SAML (Security Assertion Markup Language) is the standard that is used for sharing security information across different systems. This sharing of information is about authentication and authorization. To make the backend data sharing possible for SAML, XML is used because it allows for data sharing as well as provides SSO framework implementation features.
At the same time, the usage of XML allows the implementation of Federated identity systems which is necessary to make the whole thing work for different domains using only one ID.
How does SAML work?
All the SSO applications that we use SAML at their backend for movement of information from the clients to the service provider. So, we can say that SAML is the building block for the SSO systems to check the login credentials. SAML allows for third-party solution integrations making things extremely easy and simple, so the users do not have to log in to different applications individually.
SAML works both with SSO applications and third-party cloud applications in combination for the best productivity. The SSO apps work as an identity provider. At the same time, the cloud application works as a service provider.
So, when the user is logged in to the identity provider, the service provider and identifies it with the help of SAML with the usage of authentication responses and requests. In this case, SML data is formatted as assertions.
What are the applications of SAML?
SAML is used for business-to-business and business-to-customer applications for authentication and identification. With the usage of SAML users can easily share their credentials between different systems on a network.
When it comes to the SSO system implementation, SAML is used to meet the user authorization and user authentication goals which enable one user to be authorized for all the resources available on their network. The best part about working with SAML is that it is not restricted to typed passwords only.
When SAML is implemented different criteria for authentication can be set depending on the following things:
Passwords
Hardware key
SAML Entities
One of the main goals of SAML is to define the markup language that will be used for standardizing the authentication data encoding. In this way, an exchange between different systems is encoded for all the users and these users are known as entities. When we talk about the working of a SAML system the following are the entities involved:
End Users
All the end-users are the users on the network who need to get authentication for using any software, service, or application. These end users can be business employees as well as customers depending on the model.
Service Providers
The service provider is the system that the end-users go-to for authentication. In the case of SAML, the system provider serves authentication services with the help of web applications as well as enterprise applications.
Identity providers.
The identity providers in this system are the special case for service providers where the role is to administer all the identity information.
So, in a system of SAML for authentication and authorization, these three entities can exchange security assertions using protocols and bindings.
Components of SAML
The working of SAML is based on 4 different components and all of them are elaborated below.
- Assertions
These are the statements that contain all the information about authentication, identity, and authorization, and XML is used for formatting them.
- Protocols
Protocols are used for defining how different requests will be dealt with. These are also encoded with XML.
- Bindings
For the SAML protocol messages, the bindings are the specified formats. They help in embedding and transporting messages using different mechanisms.
- Profiles
Profiles are the last component, and they determine how different things will be used together for the interoperations of different applications. Profiles are used to determine the working of bindings, assertions, and protocols.
Final Verdict
Cybersecurity has become a necessity for this digital era and the businesses who have most of their things done digitally need the best services. SAML is important for all such businesses that are looking for amazing cybersecurity strategies because its implementation can make things extremely secure for them.
With a combination of an SSO solution, things can be made even better. In this way, the protection against data theft will become a lot better.
