GCP Audit Logs - VPC Flow Logs Disabled
Description
'Detects when Google Cloud Platform VPC Flow Logs configurations are disabled or deleted.
VPC Flow Logs capture information about IP traffic going to and from network interfaces in VPC networks, providing critical visibility for security monitoring and forensic analysis.
Disabling VPC Flow Logs reduces network visibility and may indicate an attempt to evade detection before performing malicious activities.
Adversaries may disable flow logs to hide lateral movement, data exfiltration, or command and control traffic.'
