From what I see, galaxies are given blanket protection for the most part when they have certain alliances ingal. However, in times like this, times of real war (I say real because this is a war game after all) it is acceptable and necessary to attack galaxies with your own members in it to take out threats.

As a bit of a sidenote, even if certain people will disagree with the blanket protection, it may not be a particular policy of the alliance, but it does happen in practice. It might not be complete protection, but it does help.
