Bangladesh Bank exposed to hackers by cheap switches, no firewall
This article states that the systems related to SWIFT transfers were supposed to be on an isolated network, but were not. Specifically that cheap unmanaged switches were used rather than expensive managed switches that would have allowed network isolation. Of course anyone who understands network security would point out that to rely on switch-based isolation alone is too risky. Switches can be compromised and mis-configured and sometimes don&#x27;t provide the expected level of isolation even when correctly configured.
