Description
Flow logs enable capturing information about IP traffic flowing in and out of network security groups. Logs can be used to check for anomalies and give insight into suspected breaches.
How to fix?
Set properties.retentionPolicy attribute to 90 or greater.
Set retention_policy.days to 90 or greater and set retention_policy.enabled to true.
Example configuration:
resource "azurerm_network_watcher_flow_log" "fl1" {
network_watcher_name = "${azurerm_network_watcher.main.name}"
resource_group_name = "${azurerm_resource_group.main.name}"
network_security_group_id = "${azurerm_network_security_group.sg1.id}"
storage_account_id = "${azurerm_storage_account.main.id}"
enabled = true
retention_policy {
enabled = true
days = 90
}
}
