Consolidating Cloudtrail events from multiple accounts to one bucket

Question

I'm trying to work this in the given example to write logs from Account B's Cloudtrail to Account A's bucket. I can't see the bucket in Account A in Account B's cloudtrail configuration event after adding the additional line in bucket policy under Action - s3:PutObject. :

Answer

If possible, you should consider using AWS Control Tower which will set up and maintain the Log Archive account with consolidated CloudTrail logs for you -> https://docs.aws.amazon.com/controltower/latest/userguide/how-control-tower-works.html#what-shared

If that's not possible, I suggest following the documentation Receiving CloudTrail log files from multiple accounts.

Another option is to use **[CloudTrail Lake](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-lake.html)**
