ACL Policy Limit Bucket Access

Help and Support
1

Hello Guys

I’m using Wasabi (S3 compatible).
I would like to create an ACL or Policy (I don’t know the correct name) to give a restricted access for a partner that will save some backups in a one bucket in our environment. I would like to restrict as much as possible.
Any hints how to do this?

I’m a newbie in this subject

  "Statement": [
    {
      "Effect": "Allow",
      "Action": "s3:ListBucket",
      "Resource": "arn:aws:s3:::BUCKET-NAME"
    },
    {
      "Effect": "Allow",
      "Action": [
        "s3:GetObject",
        "s3:ListBucket",
        "s3:PutObject"
      ],
      "Resource": "arn:aws:s3:::BUCKET-NAME/*",
      "Condition": {
        "IpAddress": {
          "aws:SourceIp": "54.240.143.0/24"
        }
      }
    }
  ]
}
