+# Bucket Policy Documentation
+
+## Description
+
+Bucket policy is a method of controlling access to a user's account at the
+resource level.
+There are three associated APIs:
+
+- PUT Bucket policy (see https://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketPUTpolicy.html)
+- GET Bucket policy (see https://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketGETpolicy.html)
+- DELETE Bucket policy (see https://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketDELETEpolicy.html)
+
+More information on bucket policies in general can be found at
+https://docs.aws.amazon.com/AmazonS3/latest/dev/using-iam-policies.html.
+
+## Requirements
+
+To prevent loss of access to a bucket, the root owner of a bucket will always
+be able to perform any of the three bucket policy-related operations, even
+if permission is explicitly denied.
+All other users must have permission to perform the desired operation.
+
+## Design
+
+On a PUTBucketPolicy request, the user provides a policy in JSON format.
+The policy is evaluated against our policy schema in Arsenal and, once
+validated, is stored as part of the bucket's metadata.
+On a GETBucketPolicy request, the policy is retrieved from the bucket's
+metadata.
+On a DELETEBucketPolicy request, the policy is deleted from the bucket's
+metadata.
+
+All other APIs are updated to check if a bucket policy is attached to the bucket
+the request is made on. If there is a policy, user authorization to perform
+the requested action is checked.
+
+### Differences Between Bucket and IAM Policies
+
+IAM policies are attached to an IAM identity and define what actions that
+identity is allowed to or denied from doing on what resource.
+Bucket policies attach only to buckets and define what actions are allowed or
+denied for which principles on that bucket. Permissions specified in a bucket
+policy apply to all objects in that bucket unless otherwise specified.
+
+Besides their attachment origins, the main structural difference between
+IAM policy and bucket policy is the requirement of a "Principal" element in
+bucket policies. This field is redundant in IAM policies.
+
+### Policy Validation
+
+For general guidelines for bucket policy structure, see examples here:
+https://docs.aws.amazon.com/AmazonS3/latest/dev//example-bucket-policies.html.
+
+Each bucket policy statement object requires at least four keys:
+"Effect", "Principle", "Resource", and "Action".
+
+"Effect" defines the effect of the policy and can have a string value of either
+"Allow" or "Deny".
+"Resource" defines to which bucket or list of buckets a policy is attached.
+An object within the bucket is also a valid resource. The element value can be
+either a single bucket or object ARN string or an array of ARNs.
+"Action" lists which action(s) the policy controls. Its value can also be either
+a string or array of S3 APIs. Each action is the API name prepended by "s3:".
+"Principle" specifies which user(s) are granted or denied access to the bucket
+resource. Its value can be a string or an object containing an array of users.
+Valid users can be identified with an account ARN, account id, or user ARN.
+
+There are also two optional bucket policy statement keys: Sid and Condition.
+
+"Sid" stands for "statement id". If this key is not included, one will be
+generated for the statement.
+"Condition" lists the condition under which a statement will take affect.
+The possibilities are as follows:
+
+- ArnEquals
+- ArnEqualsIfExists
+- ArnLike
+- ArnLikeIfExists
+- ArnNotEquals
+- ArnNotEqualsIfExists
+- ArnNotLike
+- ArnNotLikeIfExists
+- BinaryEquals
+- BinaryEqualsIfExists
+- BinaryNotEquals
+- BinaryNotEqualsIfExists
+- Bool
+- BoolIfExists
+- DateEquals
+- DateEqualsIfExists
+- DateGreaterThan
+- DateGreaterThanEquals
+- DateGreaterThanEqualsIfExists
+- DateGreaterThanIfExists
+- DateLessThan
+- DateLessThanEquals
+- DateLessThanEqualsIfExists
+- DateLessThanIfExists
+- DateNotEquals
+- DateNotEqualsIfExists
+- IpAddress
+- IpAddressIfExists
+- NotIpAddress
+- NotIpAddressIfExists
+- Null
+- NumericEquals
+- NumericEqualsIfExists
+- NumericGreaterThan
+- NumericGreaterThanEquals
+- NumericGreaterThanEqualsIfExists
+- NumericGreaterThanIfExists
+- NumericLessThan
+- NumericLessThanEquals
+- NumericLessThanEqualsIfExists
+- NumericLessThanIfExists
+- NumericNotEquals
+- NumericNotEqualsIfExists
+- StringEquals
+- StringEqualsIfExists
+- StringEqualsIgnoreCase
+- StringEqualsIgnoreCaseIfExists
+- StringLike
+- StringLikeIfExists
+- StringNotEquals
+- StringNotEqualsIfExists
+- StringNotEqualsIgnoreCase
+- StringNotEqualsIgnoreCaseIfExists
+- StringNotLike
+- StringNotLikeIfExists
+
+The value of the Condition key will be an object containing the desired
+condition name as that key. The value of inner object can be a string, boolean,
+number, or object, depending on the condition.
+
+## Authorization with Multiple Access Control Mechanisms
+
+In the case where multiple access control mechanisms (such as IAM policies,
+bucket policies, and ACLs) refer to the same resource, the principle of
+least-privilege is applied. Unless an action is explicitly allowed, access will
+by default be denied. An explicit DENY in any policy will trump another
+policy's ALLOW for an action. The request will only be allowed if at least one
+policy specifies an ALLOW, and there is no overriding DENY.
+
+The following diagram illustrates this logic:
