AWS VPCs Without FlowLogs Enabled

What It Does

This policy template reports any AWS VPCs (Virtual Private Clouds) without FlowLogs enabled. Optionally, it emails this report.

Input Parameters

  • Email Addresses - Email addresses of the recipients you wish to notify.
  • Account Number - The Account number for use with the AWS STS Cross Account Role. Leave blank when using AWS IAM Access key and secret. It only needs to be passed when the desired AWS account is different than the one associated with the Flexera One credential. More information is available in our documentation.
  • Allow/Deny Regions - Whether to treat Allow/Deny Regions List parameter as allow or deny list. Has no effect if Allow/Deny Regions List is left empty.
  • Allow/Deny Regions List - A list of regions to allow or deny for an AWS account. Please enter the regions code if SCP is enabled. See Available Regions in AWS; otherwise, the policy may fail on regions that are disabled via SCP. Leave blank to consider all the regions.
  • Exclusion Tags - The policy will filter resources containing the specified tags from the results. The following formats are supported:
    • Key - Filter all resources with the specified tag key.
    • Key==Value - Filter all resources with the specified tag key:value pair.
    • Key!=Value - Filter all resources missing the specified tag key:value pair. This will also filter all resources missing the specified tag key.
    • Key=~/Regex/ - Filter all resources where the value for the specified key matches the specified regex string.
    • Key!~/Regex/ - Filter all resources where the value for the specified key does not match the specified regex string. This will also filter all resources missing the specified tag key.
  • Exclusion Tags: Any / All - Whether to filter instances containing any of the specified tags or only those that contain all of them. Only applicable if more than one value is entered in the Exclusion Tags field.

The information below should be consulted when creating the credential(s).
