  These lectures provide a concise introduction to the so-called "Beyond the
Standard Model"' physics, with particular emphasis on the problem of the
microscopic origin of the Higgs mass term and of the Electro-Weak symmetry
breaking scale in connection with Naturalness. The standard scenarios of
Supersymmetry and Composite Higgs are shortly reviewed. An attempt is made to
summarise the implications of the LHC run-$1$ results on what we expect to lie
beyond (or behind) the Standard Model.
