Security practitioners have spent decades developing methods for strong authentication to mitigate these risks that are easy to use and as secure as possible. Single sign-on (SSO) systems allow users to authenticate to a central application one time and then automatically authenticate to other applications and systems.
Fortunately, SSO services for the cloud, known as Authentication as a Service (AaaS), deliver some of the benefits of SaaS to authentication management. Businesses, governments and other organizations adopt AaaS for a number of reasons, including expanded user bases as well as budgetary and time concerns.
The scope of users has expanded beyond organizational boundaries; customers, suppliers, contractors and other people outside the organizations now have access to enterprise Web applications. Provisioning and managing access for these users cannot always be linked to an internal directory or a human resources process.
Authentication and identity management systems can be complex and costly, but AaaS brings the
