  The renormalization of the Minimal Supersymmetric Standard Model (MSSM) is
presented. We describe symmetry identities that constitute a framework in which
the MSSM is completely characterized and renormalizability can be proven.
Furthermore, we discuss applications of this framework for the determination of
symmetry-restoring counterterms, the gauge dependence of tan(beta) and the
derivation of non-renormalization theorems.
