Securing a BPEL Composite in Oracle SOA Suite

Recently I was researching BPEL composites in the Oracle SOA Suite and I found this excellent blog post by Shreekanta Roy Chowdhury about securing a BPEL composite using Oracle Enterprise Gateway. The post even provides a very useful Google doc (with screenshots!) of how to install and configure OEG. Highly recommended reading, if you are working with this particular set of products.
