IT heterogeneity, or the establishment of duplicate but separate critical infrastructure systems, was noted by SentinelOne Chief Information Security Officer Alex Stamos to increase in adoption following the widespread global IT outage stemming from a botched CrowdStrike Falcon update, according to SC Media.
"One thing is you could end up with is companies running on separate cloud systems where you end up with less operating leverage across cloud systems, different authentication, and operating domains.
Any disaster recovery system is going to be running in a completely different cloud," said Stamos in a SC Media briefing.
Organizations were also urged by Stamos to take cyber resilience more seriously by adopting security by design principles.
Achieving cyber resiliency would require the establishment of smart system architecture and design and the implementation of front-end code verification and input validation in cloud systems, as well as the inclusion of access control checks in data validation and access layers, Stamos added.
