3. Does SSO Work if Physical ID Verification Is Required?
The combination of SSO and the Common Access Card for authentication, which blends encryption and two-factor authentication, is required for government and military work. A CAC can be used with a physical smart card reader, which can be tied to a cloud-based SSO.
4. Does SSO Work Well with Legacy Technology?
That depends on the age of the legacy technology, whether the technology is still supported by the vendor, and whether the SSO is in-house or cloud-based. Some legacy systems may not expose all of the integration points that need to be secured.
5. Are There Challenges to Implementing SSO?
SSO can be expensive and complicated to install for legacy technology, custom-built applications or systems, or systems that require middleware to ensure secure implementation. Agencies should take this into consideration during planning.
