After a brief introduction to the properties of the Standard Model Higgs boson (especially the bounds on its mass from various considerations before the eventual discovery of a standard-like Higgs boson at CERN), I will describe what our community calls `the hierarchy problem'. I will then mention two broad ways to address this problem by associating the Higgs boson with some symmetries; more specifically, the Higgs boson could arise from a supersymmetric theory, or, it could be a pseudo-Nambu-Goldstone boson which arises in a composite Higgs scenario.
