must be part of your
mobile strategy

5. The Essence of the Problem:
Secure Mobile Access to Apps and Data
API/Service
Servers
How Do We Make APIs Available?
 Firewall mazes
Firewall 2
 Diversity of clients and back end systems
 Clients and servers change at different
rates
Firewall 1
Directory
Enterprise
Network
Internet
Of Particular Interest:
 Authentication, Authorization & SSO
 Secure Transmission
API/Service

6. We Want Classic SSO In An Active Profile For REST
API/Service
Servers
Could leverage WS-Fed here
 SAML’s second act?
Directory
Internet
Apps making
RESTful API
calls

7. But We Also Want Local App SSO
API/Service
Servers
“Like a VPN… but without all
of the negatives”
Single Sign On App Group
(these apps will share
sign-on sessions)

C
So now it’s getting
interesting…

10. Solution: Native Single Sign-On SDK For Mobile
Developers
Strong Security for Mobile Apps
API Servers
 Cross-platform and built for a consumer or BYOD world
 100% Standards-based using OAuth+OpenID Connect
 X-app SSO with multi-factor auth & secure channel
 X.509 Certificate provisioning for strong auth and transaction signing
One time PIN

11. Client Deployment Strategy
 Don’t make me work hard
– But give me a strong and extensible security model
 Transfer of security responsibility
– Let developers do what they do best
 Simple SDK
– Align with common development time environments
 iOS, Android, Javascript, etc
 Mirror REST frameworks
 Future
– Aspects, wrapping, etc.
