We provide necessary and sufficient conditions for normal stability of a linear Hamiltonian system with n degrees of freedom. We also formulate some conditions for strong stability, which show similarities between the concepts of normal stability and strong stability. In the last section, we make the necessary adaptations to extend the concept of normal stability and the results of this paper to periodic Hamiltonian systems.
