Tips: Best Practices for The Other AWS Amazon S3 Resources

In addition to the aws_s3_bucket_public_access_block, AWS Amazon S3 has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.

risk-label

aws_s3_bucket_public_access_block

Ensure S3 bucket-level Public Access Block restricts public bucket policies

It is better to enable S3 bucket-level Public Access Block if you don't need public buckets.

risk-label

aws_s3_bucket

Ensure S3 bucket access policy is well configured

It is better to configure the S3 bucket access policy properly to limit it unless explicitly required.

Review your AWS Amazon S3 settings

In addition to the above, there are other security points you should be aware of making sure that your .tf files are protected in Shisho Cloud.
