Network Segmentation vs Air Gapping: Connectivity or Complete Disconnection?
Key Takeaways Network segmentation creates controlled boundaries within networks using VLANs and firewalls, while air gapping provides complete physical or logical disconnection from external systems Air-gapped systems offer immunity from ransomware and remote attacks but require complex operational procedures for data transfer and system maintenance Critical infrastructure sectors like nuclear facilities and power grids rely on data diodes and strict air gap requirements to meet regulatory compliance The Colonial Pipeline attack exposed vulnerabilities in network segmentation approaches, highlighting when complete disconnection becomes essential for security Choosing between connectivity and complete isolation involves balancing operational flexibility against maximum protection requirements When protecting critical systems and sensitive data, cybersecurity professionals face a fundamental choice between controlled connectivity and complete disconnection. Network segmentation offers f...
