De acordo com o Gartner, líder mundial em pesquisa e aconselhamento sobre tecnologia, uma estratégia SSO (single sign-on) bem executada reduz o número de incidentes do suporte relacionados a senhas e fornece aos usuários melhor conveniência e processos mais eficientes de autenticação. Uma boa estratégia dará aos usuários menos razões de anotar senhas. Porém, uma só senha permitindo acessar todos os sistemas pode levar ao acesso comprometido deles.



Gartner Says Through 2016, Federated Single Sign-On Will Be the Predominant SSO Technology, Needed by 80 Per Cent of Organisations



A well-executed single sign-on (SSO) strategy reduces password-related support incidents and provides users with improved convenience and more-efficient authentication processes, according to Gartner, Inc. A sound SSO strategy will give users fewer reasons to write down passwords. However, one password providing access to all in-scope systems can lead to compromised access to those systems.

“Organisations implementing SSO, particularly to systems that hold sensitive data, should implement risk-appropriate authentication methods with the SSO system,” said Gregg Kreizman, research vice president at Gartner. “Solutions are not ‘one size fits all,’ and solutions that provide SSO to all target systems may be deemed too expensive. Therefore, a best practice is to identify the tactical and strategic approaches that reduce enough of the problem space over time and within budget.”

Mobile devices can pose further challenges for SSO. “The proliferation of mobile phones and tablets with a variety of operating systems has created the latest and greatest challenges to authentication and SSO,” said Mr Kreizman. “Web-architected applications can often be supported with existing access management tools, such as web access management (WAM) and federation, because smartphones and tablets have web browsers. Native mobile resident applications can create a gap in SSO support, and market offerings to resolve the issues are currently immature, proprietary, or not comprehensive enough to support multiple device and operating system variants.”

Gartner has identified the following steps and framework that should be used to appropriately scope the target solution set.


Assess the Current Environment and Pain Points

The first step is to scope the problem space by identifying the user population and use cases that require a solution, and to inventory the target systems, their architectures and the anticipated lifetimes.
