Morphology
The noun 'bastion' already denotes a strong defensive position or institution and the preposition 'against' signals opposition or protection, so their combination transparently yields the meaning ‘a strong defense or safeguard versus X’. This compositional pattern (fortress/defender + against) is cross-linguistically common and would be understandable to a B1 learner who knows both constituents.
Etymology
Bastion against comes from castles: a bastion was a strong wall or tower that stuck out so soldiers could fight enemies coming against it. So calling something a bastion against a problem gives the image of a solid 'defense' that protects people from that danger.
