Frequently Asked Questions
Cloud Native Security Fabric Mitigations and ControlsCNSF
Aviatrix Zero Trust CNSF is pertinent to this incident as it would likely have constrained the attacker's ability to move laterally and exfiltrate data by enforcing strict segmentation and identity-based access controls.
Control: Cloud Native Security Fabric (CNSF)
Mitigation: The attacker's initial access may have been limited to a single workload, reducing the potential for further exploitation.
Control: Zero Trust Segmentation
Mitigation: The attacker's ability to escalate privileges could have been constrained, limiting access to critical systems.
Control: East-West Traffic Security
Mitigation: The attacker's lateral movement would likely have been restricted, preventing access to adjacent workloads.
Control: Multicloud Visibility & Control
Mitigation: The attacker's command and control channels may have been detected and disrupted, impeding data exfiltration.
Control: Egress Security & Policy Enforcement
Mitigation: The attacker's data exfiltration efforts would likely have been limited, reducing the volume of data compromised.
The financial impact of the attack may have been mitigated by limiting the scope of data exfiltrated.
