How does Single Sign-On work?
SSO works on the basis of an authentication mechanism where a user logs in once. This user then gets access to multiple linked applications without having to log in again and again. This is done using an SSO token.
The moment a user logs in to a Single Sign-On matching system, the authentication server creates a token with the credentials. This token is then passed on to other linked applications that accept it as valid proof of identity. By using this technique, the user does not have to enter his login details over and over again.
Are there different types of Single Sign-On?
There are different types of SSO solutions. It depends on which technology and authentication protocol is used. At DISA we use the following variant: Microsoft Entra ID Single Sign-On, based on the OpenId protocol. This method is suitable for business environments and allows for secure and streamlined access to various systems.
Benefits of Single Sign-On
Single Sign-On has a number of advantages for both the user and the organisations. But what are the benefits of SSO? Below, we’ll discuss some of the key benefits.
Increased productivity
With SSO, you don’t have to log in as often, because the tool automatically takes care of this for you. This way you not only save time but also avoid frustration. This increases efficiency within the organisation.
Enhanced Security
SSO increases security by using unique passwords and central storage in your secure vault. This reduces the chance of weak or reused passwords. This way, you’ll make it harder for hackers to access sensitive data.
Less IT support required
SSO increases security by using unique passwords and central storage in your secure vault. This reduces the chance of weak or reused passwords. This way, you’ll make it harder for hackers to access sensitive data.
Implementation of Single Sign-On at DISA
At DISA, we have implemented SSO to make the screening process smoother. It is also made simpler and safer in this way. The integration with Microsoft Entra ID and the OpenID protocol allows users to gain direct access to all relevant systems after a single login.
Note: At the moment this can only be used by organisations. Users and organisations benefit from improved accessibility and security through a streamlined and efficient process.
FAQ about Single Sign-On
With Single Sign-On, access to digital systems becomes easier, more efficient and more secure for both users and organisations. Here we answer some frequently asked questions about SSO.
SSO offers strong security benefits, but there are also risks if not managed properly. A single hacked account can give access to multiple systems. Therefore, it is essential to deploy additional security measures, such as Multi-Factor Authentication (MFA). When used correctly, SSO systems are actually more secure because passwords are less often reused or forgotten. DISA can advise and support you to optimally secure your SSO system. SSO was already secure, and with the right measures in place, you can further strengthen security.
SSO integrates with a wide range of applications and platforms, including cloud-based software, internal business applications, and standards-compliant web applications such as OpenID Connect.
SSO provides a smoother user experience by reducing the time employees spend logging in and managing passwords. This increases productivity and reduces frustration.
