IA-02(10) Single Sign-on

Title

Single Sign-on

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.

Parameters

ia-02.10_odp: system accounts and services

Assessment objective

IA-02(10) a single sign-on capability is provided for [Assignment: system accounts and services].
