The recent SolarWinds supply chain cyberattacks serve to underscore an age-old cybersecurity tenant, and the reason we need to continue beating the drum as cybersecurity professionals: Use a layered approach to OT security.
This incident highlights a rare, specific use case of a nation state threat actor, an Advanced Persistent Threat (APT). In this particular case, layers provided somewhat limited value, but helped keep the less skilled attackers – about 99% of those on the playing field – at bay.
Technology boundaries can be used to lessen the impact of (but unfortunately not prevent) nation state APTs.
