SCCM 2012 with SCM - support for non-Windows?

Hello all,

As part of compliance configuration, i came across the Microsoft's Security Compliance Manager 3.0 (latest version) mainly for compliance and remediation. But after going through their docs, I feel SCM is used only on Windows OS (clients or servers). 

a] Does SCM support contact with non-Microsoft vendors to import security baselines?

b] Does SCM support audit, compliance and remediation on non-windows OS devices? (clients/servers)

Any help is greatly appreciated.

thanks
