"Effect": "Allow",
"Action": "s3:*",
"Resource": "*"
},
{ // second, deny access to all buckets except for the particular bucket
"Action": [
"s3:*"
],
"Effect": "Deny",
"Resource": [
list-of-my-other-buckets
]
},
{ // third, since we've already given * permissions, the bucket has full
// permissions, and we need to restrcit all the permissions we don't want to give
