Assuming they are cut off from food, water, and ammunition, and it is a truly sustained attack, yes. However, not if it's piecemeal attacks such as the "a few husks/avatars" or "a few humanoid machines", which were the comments that I was originally addressing with my own "defenders" theory, then no. Even if cut off from the rest of the Citadel, a decent-sized force of Special Response officers would likely be able to hold out indefinitely.
