We're planning a secure Node.JS server, which uses several third-party web services. Each requires credentials that will need to be configured by the operations team.
Clearly they could simply put them in plain text in a configuration file.
Microsoft .NET seems to offer a better option with DPAPI - see Credential storage best practices. Is there a way to make this available through IISNode? Or is there any other option to secure such credentials within Node-JS configuration?
There's an extensive discussion of several options here, including the two suggested by xShirase:

User-defined services solves the problem, but only for Cloud Foundry.
This blog http://encosia.com/using-nconf-and-azure-to-avoid-leaking-secrets-on-github/ points out that you can often set environment variables separately on servers, and suggests using nconf to read them and config files separately.
I still wonder if there are specials for IIS?
There is 2 ways to do it securely :
First one is to use command line parameters when you launch your app.
These parameters are then found in process.argv
So, node myapp.js username password
would give you :
process.argv[0]=node
process.argv[1]=/.../myapp.js (absolute path)
process.argv[2]=username
process.argv[3]=password
Second is to set the credentials as ENV variables. It is generally considered as the best practice as only you have access to these variables.
You would have to set the variables using the export command, than you'd access it in process.env
