.NET interoperability, Kerberos, SPNEGO, Id Propagation - All things Microsoft! - OWSM 11g - Revisited

In a previous blog post - I briefly talked about interoperability with Microsoft and support for Kerberos, SPNEGO, NTLM, etc in OWSM. So I wanted to revisit that post and address a few aspects:

SPNEGO support

In that blog post - I mentioned that SPNEGO is something we don't support in OWSM.

In PS6 with the introduction of the support for REST security - we also added support for SPNEGO. While the key driver was REST services and securing REST services - we support SPNEGO policies for HTTP/SOAP services as well.

In fact one of things customers will notice is that many of the policies introduced for securing REST services are also supported for HTTP/SOAP web services.

SPNEGO support is documented here:

http://docs.oracle.com/cd/E28280_01/web.1111/b32511/policies.htm#CHDEJIIF

http://docs.oracle.com/cd/E28280_01/web.1111/b32511/assertions.htm#CHDBICJC

http://docs.oracle.com/cd/E28280_01/web.1111/b32511/policies.htm#CJAIEDEG

Note: OWSM still doesn't support NTLM.

Interoperability with Microsoft environments.

One of the most common questions from customers is around can we use SAML to do identity propagation b/w Microsoft and Oracle based environments and the use of ADFS as the STS for enabling SAML based identity propagation.

In PS6 - we have certified with ADFS ( in addition to the certification with Oracle STS, OpenSSO STS).

Client side Kerberos support

It appears that many people looked at the figures in the previous blog post and assume we don't support Kerberos on the client side in OSB. I just wanted to clarify that we do in fact support Kerberos policies on the client side - so for - you can do the following:


The key limitation is that you cannot use kerberos across multiple hops as I mentioned in the previous blog post. However you can definitely use Kerberos policies to secure your web services clients.

Identity Context support in OWSM - 11g

Here is another quick post about yet another new feature in PS6. As many of you know we have supported identity propagation for a long time. However as things have evolved - it is clear that propagating just identities is not sufficient. We need to propagate additional contextual information - this may include for ex:

a) In the Mobile world - for example this can include whether the user is using a device that is jail broken or not

b) In the Banking space - the geo-location from where an ATM debit card or credit card might be getting used by the user.

In fact Marc Boroditsky spoke about this in Oracle Open World 2012.

This sets up the need for propagating not just the identity but the entire context! In PS6 we have taken a step in this direction.

Note: There are still some limitations - SOA Suite/OSB - for example don't yet support the ability to propagate the entire identity context.

OWSM Mobile Agent for ADF Mobile

Oracle released Mobile Application development framework - called Oracle ADF Mobile sometime back. More details about the Oracle ADF Mobile framework can be found here.

In order to secure the REST/SOAP communication b/w the ADF Mobile App and the backend services - OWSM team has developed an OWSM Mobile Agent.

The capabilities right now are fairly limited - especially when you consider what is supported in the Non-Mobile case! The OWSM Mobile Agent only supports Basic Auth and Basic Auth over SSL and WS-Security Username Token and WS-Security Username Token over SSL policies.

More details about the policies supported can be found here. The good news is building a Mobile client to backend REST/SOAP web service is very similar to how you do in the "Big ADF" world i.e. you use Web Service Data Controls!

Here is the revised layered Service security diagram that I discussed initially in this post:

layered service security

P.S:I didn't see an example of how to build a Mobile App that can make Web Service calls on the Oracle ADF Mobile page; if time permits - I will post some How To's on this front...

Update: Some folks pointed me to this blog post on ADF Mobile Introduction that actually covers how to build and secure web service clients. There is also an official ADF Mobile blog for more details...

OSB and OWSM integration enhancements - 11g

In my previous post, I described one of the key features that we added in OWSM for PS6 was support for securing REST services. I forgot to mention that another key addition in PS6 relates to the OSB/OWSM integration. The integration has been enhanced to address some of the more common issues that were raised by customers.

Two key enhancements in this area include:

a) Support for securing OSB REST services with OWSM Policies.

Note: OSB has not certified all the REST security policies OWSM supports in PS6.

b) Support for Attachments (MTOM, SwA) and OWSM security policies

More details on what is supported in OSB in PS6 can be found here.

FMW PS6 (11.1.1.7.0) released!

Just a quick note - FMW PS6 has been released. OWSM is part of the FMW release train. As was the case with the previous FMW Patchset release - this is a feature bearing release.

The OWSM PS6 documentation describes as part of what's new section an exhaustive list of features:

The following new features and enhancements have been added to the current release of Oracle Web Services Manager:

In future blog posts I will post in more detail about some of the features - but in this blog post I wanted to highlight one particular features that I think customers are going to find very useful:

Securing REST services (a.k.a Servlet Application Security)

Customers can build REST services in one of two ways:

  • As Servlet applications without using any REST technology stack
  • Using REST stacks like Jersey JAX-RS

In PS6 - OWSM support's securing REST services built using either methodologies. So all the capabilities and power of OWSM to secure SOAP services can now be used for securing REST services.

Here is are some quick doc pointers:

http://docs.oracle.com/cd/E28280_01/web.1111/e13734/rest.htm#BHABFDGJ

http://docs.oracle.com/cd/E28280_01/web.1111/b32511/policies.htm#CHDEJIIF

Note: In this release OWSM does NOT SUPPORT securing REST clients - for example REST Clients built using the Jersey JAX-RS stack.

In this blog I will discuss mainly features supported by Oracle Web Service Manager (OWSM).
