Control: 171 EC2 VPN connections should have logging enabled

Description

This control checks whether an AWS Site-to-Site VPN connection has Amazon CloudWatch Logs enabled for both tunnels. The control fails if a Site-to-Site VPN connection doesn't have CloudWatch Logs enabled for both tunnels.

AWS Site-to-Site VPN logs provide you with deeper visibility into your Site-to-Site VPN deployments. With this feature, you have access to Site-to-Site VPN connection logs that provide details on IP Security (IPsec) tunnel establishment, Internet Key Exchange (IKE) negotiations, and dead peer detection (DPD) protocol messages. Site-to-Site VPN logs can be published to CloudWatch Logs. This feature provides customers with a single consistent way to access and analyze detailed logs for all of their Site-to-Site VPN connections.

Remediation

To enable tunnel logging on an EC2 VPN connection, see AWS Site-to-Site VPN logs in the AWS Site-to-Site VPN User Guide.

    count(*)
  from
    aws_vpc_vpn_connection,
    jsonb_array_elements(options -> 'TunnelOptions') as t
  where
    (t -> 'LogOptions' -> 'CloudWatchLogOptions' ->> 'LogEnabled')::bool
  group by arn
)
select
  a.arn as resource,
  case
    when b.count >= 1 then 'ok'
    else 'alarm'
  end as status,
  case
    when b.count = 1 then a.title || ' has logging enabled for one tunnel.'
    when b.count = 2 then a.title || ' has logging enabled for both tunnels.'
    else a.title || ' has logging disabled for both tunnels.'
  end as reason
  
  , region, account_id
from
  aws_vpc_vpn_connection as a
  left join tunnel_logging as b on a.arn = b.arn;
