Frequently Asked Questions
Cloud Native Security Fabric Mitigations and ControlsCNSF
Aviatrix Zero Trust CNSF is pertinent to this incident as it likely limits attackers' ability to move laterally, escalate privileges, and exfiltrate data by enforcing strict segmentation and identity-aware policies.
Control: Cloud Native Security Fabric (CNSF)
Mitigation: While initial exploitation may still occur, Aviatrix CNSF would likely limit the attacker's ability to leverage the compromised appliance to access other network segments.
Control: Zero Trust Segmentation
Mitigation: Even with elevated privileges, attackers would likely find their access constrained to predefined segments, reducing the risk of unauthorized access to sensitive systems.
Control: East-West Traffic Security
Mitigation: Lateral movement would likely be restricted, as CNSF enforces policies that limit inter-workload communications to authorized paths.
Control: Multicloud Visibility & Control
Mitigation: Command and control channels would likely be detected and disrupted, as CNSF provides comprehensive visibility into network traffic patterns.
Control: Egress Security & Policy Enforcement
Mitigation: Data exfiltration attempts would likely be blocked or flagged, as CNSF enforces strict egress policies and monitors outbound traffic.
Operational disruptions would likely be limited in scope, as CNSF's segmentation and control mechanisms contain the blast radius of attacks.
