Issue

  • Why there are out-bound ipv4 traffic on ports 443, 9997 to s3 buckets (ROSA).
  • I can see some traffic to s3 bucket from ROSA cluster through port 443 and 9997. What are they used for?
  • Our security team has found an issue where an outbound traffic is being initiated by/through a public subnets. The public subnet should only be answering to new sessions and not initiating them. We found some 443, 9997 traffic to s3 buckets and others. What are these traffic ?
