S3 Bucket Policies

A list of S3 bucket policies that help protect S3 buckets. All policies can be customized and combined to create templates that can be deployed using CloudFormation or AWS CLI..

A policy that denies any access to the S3 bucket that is not encrypted in-transit (uses HTTP instead of HTTPS).

A policy that denies an S3 bucket or any uploaded object with the attribute x-amz-acl having the values public-read, public-read-write, or authenticated-read. This means authenticated users cannot change the bucket's policy to public read or upload objects to the bucket if the objects have public permissions.

A policy that grants permissions to any user to perform any Amazon S3 operations on objects in the specified bucket. However, the request must originate from the range of IP addresses specified in the condition.

A policy that allows s3:GetObject permission with a condition, using the aws:referer key, that the get request must originate from specific webpages.

A policy that denies any Amazon S3 operation on the bucket if the request is not MFA authenticated.

A policy that denies any requests to read objects in an S3 bucket that don't come from a specific Cloudfront distribution. You must specify the canonical user ID for your CloudFront distribution's origin access identity.

A policy that grants the s3:GetObject permission to any public anonymous user.

An S3 Bucket policy grants access to AWS Config and AWS CloudTrail to deliver log files to the S3 bucket.
