This presentation explains the varioius security scenarios for your mobile and Web applications, and APIs. We go into the specifics of OAuth, SAML, SSO, authentication/authorization, policy, protection and a host of other related issues that will help you understand how to keep your data secure.

The Security Landscape
• Authentication, Authorization, SSO
• Licensing
• Quota Management
• Protection
• Role of Policy

Authentication/Authorization/SSO
• Confusing array of standards:
– OAuth
– SAML
– OpenID
– SCIM
• A variety of App types
– Desktop
– Mobile
– Web
• Enterprise SSO and its set of legacy
systems

4. Copyright © 2001-2013 SOA Software, Inc. All Rights Reserved.
Use Cases
• Enterprise support for public credentials
– Tiered service
• Providing APIs for Web applications
• Enabling a new API digital channels using
OAuth. Perhaps in conjunction with:
– SAML
– OpenID
• Extending/modernizing Enterprise SSO via:
– OpenID Connect
– SAML

Combining SAML and OAuth
1. Try to get OAuth Token
2. Redirect with SAML
Authentication Request
3. Log the user in, create
the SAML assertion and
redirect again
4. Verify SAML token and
issue OAuth token
5. App makes call to API
6. Gateway validates OAuth
token and performs fine
grained authorization

Licensing
• You may want to enable a business model based on
different:
– Operations or resources
– Levels of service
• The licenses control:
– OAuth Authorization
Scopes
– Document visibility
– Quota policies

Quota Management
• You probably want different
licenses with different levels of
service
• The levels of service are:
– Throughput
– Bandwidth consumed over time
– Concurrency
– Availability
• Apps could either be cut-off or
events generated when quotas
are exceeded. Events can be
used for overage billing

Protection
• Denial of Service
• Injection Attacks
• XSS
• Viruses

The Role of Policy
Lower cost and risk:
• Separate functional and non-
functional
• Decouple changing standards from
your implementation
• Provide multiple options depending
on the channel
• Mediate

11. Copyright © 2001-2013 SOA Software, Inc. All Rights Reserved.
The Role of Policy
• An API is exposed externally that
has a security policy of:
– OAuth with SAML2
• Internally, the security policy is:
– WSS/SAML
• The system can use these
declarative policies to
automatically convert the OAuth
token inbound to the WSS/SAML
token that is required by
downstream services
