AWS aws_cloudwatch Mappings

AWS CloudWatch provides various metrics including CPU utilization, connections, disk space, memory, bytes sent/received, and the number of running containers among others. The following metrics (not an exhaustive list) could be used to detect if the usage of a resource has increased such as when an adversary hijacks a resource to perform intensive tasks. Linux/Mac OS ------------- cpu_time_active cpu_time_guest cpu_usage_active cpu_usage_guest disk_free disk_total disk_used ethtool_bw_in_allowance_exceeded ethtool_bw_out_allowance_exceeded ethtool_conntrack_allowance_exceeded mem_active mem_available_percent mem_free net_bytes_recv net_bytes_sent net_packets_sent net_packets_recv netstat_tcp_established netstat_tcp_listen processes_running processes_total swap_free swap_used Containers ---------- CpuUtilized MemoryUtilized NetworkRxBytes NetworkTxBytes node_cpu_usage_total node_cpu_utilization node_filesystem_utilization node_memory_utilization This mapping is given a score of Partial because it is not possible to differentiate between an authorized and unauthorized increase in resource utilization.

AWS CloudWatch provides various metrics including CPU utilization, connections, disk space, memory, bytes sent/received, and the number of running containers among others. The following metric could be used to detect if an adversary deployed a new container in the environment. node_number_of_running_containers This mapping is given a score of Partial because it is not possible to differentiate between an authorized and unauthorized deployment of a new container.

AWS CloudWatch uses TLS/SSL connections to communicate with other AWS resources which protects against network sniffing attacks. As a result, this mapping is given a score of Significant.
