Morphology
The meaning 'a set of devices or measures for protection' is directly and transparently derivable from combining 'security' (measures to protect) with 'system' (a collection of interacting components). This is a regular noun–noun compound pattern that is cross-linguistically common and composed of relatively high-frequency words, so a B1 learner who knows both constituents will understand the MWE.
Etymology
Security system in computing comes from the image of a building with walls, gates and guards: security means keeping things safe and a system is parts that work together. So it means 'a set of rules and tools that control who can enter a computer network'.
