The osi 7 layer model is an integral part of networking security - understanding it is important for ecommerce security. Security quiz network security isn't a silver bullet either, of course even using unidirectional gateways (the network-layer equivalent to application whitelisting, where absolute protection is provided at the physical layer), there's the chance that a hardened network shell can be bypassed, exposing the gooey interior of networked hosts.
