Question

Does Sencha Touch offer any security model?

How compatible it is with custom or other predefined security models like Spring?

Answer 1

Sencha Touch is agnostic: that is, it neither provides a security model of its own nor limits you to the use of a particular server-side model. If Spring is your thing, and if its security model is accessible by a REST-like API (which is the case), then it's perfectly feasible.

That said, there are at least two other dimensions to consider: one is transport layer security, the other is encrypted local storage. Sencha has nothing to do with these, either, but they're also important to your app. TLS is a deployment concern; encrypted local storage is more or less a DIY project, although there are some libraries out there to assist, javascrypt and Stanford Javascript Crypto Library among them.
