IA-2(10) Single Sign-on
Control enhancement of IA-2 Identification and Authentication (Organizational Users)
Control
Provide a single sign-on capability for [Assignment: system accounts and services].
Discussion
Single sign-on enables users to log in once and gain access to multiple system resources. Organizations consider the operational efficiencies provided by single sign-on capabilities with the risk introduced by allowing access to multiple systems via a single authentication event. Single sign-on can present opportunities to improve system security, for example by providing the ability to add multi-factor authentication for applications and systems (existing and new) that may not be able to natively support multi-factor authentication.
Need IA-2(10) implemented and evidenced?
We assess where you stand against this control, document the gap, and build the remediation plan your auditor and your board will both accept.
