Frequently Asked Questions
Cloud Native Security Fabric Mitigations and ControlsCNSF
Aviatrix Zero Trust CNSF would likely reduce the attack surface and blast radius of this industrial control system exploitation by implementing network segmentation and east-west traffic controls that could constrain lateral movement between OT devices.
Control: Cloud Native Security Fabric (CNSF)
Mitigation: Network visibility and fabric controls would likely reduce the reachability of industrial control modules by constraining direct network access paths to these critical OT assets
Control: Zero Trust Segmentation
Mitigation: Microsegmentation policies would likely constrain the scope of unauthenticated access by isolating industrial control modules within restricted network zones with limited connectivity permissions
Control: East-West Traffic Security
Mitigation: Traffic inspection and segmentation controls would likely constrain lateral movement between industrial systems by reducing connectivity paths available for targeting additional OT devices across network segments
Control: Multicloud Visibility & Control
Mitigation: Centralized visibility and policy controls would likely reduce the effectiveness of malicious CIP packet delivery by constraining protocol-based communication paths to industrial control systems
Control: Egress Security & Policy Enforcement
Mitigation: Egress controls would likely constrain outbound data flows that could contain industrial network topology information by limiting unauthorized data transmission from compromised OT environments
Operational disruption to manufacturing, food processing, transportation, and water treatment systems would likely be reduced in scope through network isolation that limits the number of affected industrial control systems
