Single Sign-On (SSO) is a session and user authentication service where one set of credentials – typically a username and password – can be used by an organization’s users to access multiple apps.
SSO delivers tighter control for admins, helping to keep an organization’s data more secure by providing access only to users who really need it. At the same time, it makes operations more secure at the user level too – when users don’t need to remember a large number of credentials, they would be more willing to use stronger passwords.
Besides its inherent security, SSO also simplifies provisioning and de-provisioning, which in effect also increases security by preventing unauthorized access to apps and data.
How secure is your SSO?
Some misconceptions also exist regarding SSO – key among them is that SSO leads to an increased security risk, almost like putting all your eggs in one basket. After all, with one system controlling access across all of an organization’s applications, what if that single system is compromised?
It is therefore important to understand that SSO functions through a system of secure tokens which do not carry any sensitive data, making it a very safe proposition. We’ll explore exactly how this works, and how these tokens ensure security, later in this article.
What are SSO tokens and how do they work?
SSO tokens are tiny sets of digitally signed structured information to ensure mutual trust between parties.
It’s like an exclusive club with select invitees, where guards at the entrance check, approve, and stamp each guest’s hand. Event staff will know the exact shape and color of the stamp used and therefore authenticate the entry. Similarly, in the digital world, the service and identity providers communicate via tokens.
Tokens don’t include sensitive data like user’s password or biometric information, ensuring that any interception or attack on the tokens does not reveal the information. The same token can be used to add on new services to the same SSO platform as well. It facilitates identity verification separately from other cloud services, making SSO possible.
Data Security through SSO
SSO improves enterprise security as it reduces the number of attack surfaces because users only log in once each day and only use one set of credentials.
It also significantly reduces the possibilities of password-related hacks. With SSO, users only need to remember one password for all their applications. So, they are more likely to create complex and hard-to-guess passwords. They are also less likely to reuse passwords or write them down.
Another reason SSO is popular among enterprises is that it allows scaling up. Both access to new apps and addition of new people can be managed without sacrificing security, because identity and access management are already addressed. And rapid provisioning and deprovisioning without needing to worry about human error means more reliable and secure access management.
For added security, SSO can also be paired with Multi-Factor Authentication (MFA), where additional factors of authentication are required beyond just the user’s password, to reconfirm the identity of the user.
