"""
Build a CloudFormation template allowing for secure CloudTrail log
aggregation and fine grained access control to SNS topics for notifications
of new CloudTrail logs
The reason that we create IAM roles for each client AWS account in order to
enable clients to read their own CloudTrail logs, instead of merely
delegating access to them in an S3 bucket policy is that
"Bucket owner account can delegate permissions to users in its own account,
but it cannot delegate permissions to other AWS accounts,
because cross-account delegation is not supported." :
http://docs.aws.amazon.com/AmazonS3/latest/dev/example-walkthroughs-managing-access-example4.html
As a consequence we *can* delegate bucket permissions to client AWS
accounts but we *can not* delegate object permissions (the log files
themselves) to client AWS accounts.
Example config :
AccountRootARNs:
- arn:aws:iam::012345678901:root # Sales
- arn:aws:iam::123456789012:root # HR
- arn:aws:iam::234567890123:root # Marketing
CloudTrailLogConsumers:
- arn:aws:iam::345678901234:user/security_team # Security team user
- TrustedARN: arn:aws:iam::456789012343:root # CloudCo Third Party
TrustingARNs:
- arn:aws:iam::012345678901:root # Sales
- arn:aws:iam::234567890123:root # Marketing
- TrustedARN: arn:aws:iam::567890123434:root # Other.com Third Party
