These are typically used in simple deployments, and are used by only a few protocols like VPN filters and route maps (though route maps can also use extended ACLs, so it’s rarely used in this case either). Unlike the condition key, the value string bucket-owner-full-control is not actually validated within the policy, since it's just a string, but if you don't specify a valid value, it will simply never match. A standard ACL is designed to protect a network using only the destination address. Otherwise there are not a lot of options for allowing/denying requests related to headers. There are global condition keys like aws:SecureTransport that can be used to deny a request that isn't using HTTPS, and aws:UserAgent that evaluates against the HTTP User-Agent header, but note the documented caveat that this "should not be used to prevent unauthorized parties from making direct AWS requests" because it is easily forged by the user agent. Most other HTTP headers are not subject to policy conditions, and you can't use, e.g. Put the name of the bucket or list of buckets into 'buckets.list' file & run the bash script below. 91/263/EEC, the unit should not be directly connected to the Public. Then under needed prefix list all those objects. acl(ObjectCannedACL.PUBLICREAD) on my PutObjectRequest. G.3.1 Adaptive Control Loop (ACL) Components. Some are awarded in accordance with formulas (mandatory grants) established in legislation, while others are awarded in a competitive process (discretionary grants). ACLs are used to filter traffic based on the set of rules defined for the incoming or outgoing of the network. Note the absence of the x-amz-aclpublic-read query parameter on the presigned URL generated by the Java SDK v2 (2.13.19), even though I have set. ACL awards more than one billion dollars in grants, primarily to state and local governments, nonprofit organizations, institutions of higher education and small businesses. It is not an arbitrary header match, even though such a capability might be handy at times. Access-list (ACL) is a set of rules defined for controlling network traffic and reducing network attacks. It is a list of access control entries to restrict the hosts that are allowed to connect to the Oracle database. ![]() Specifically: s3:x-amz-acl is an S3-specific IAM policy condition key that happens to be named exactly the same as the header that it matches. Access Control List (ACL) is a fine-grained security mechanism. This policy snippet requires that the request contain the specification of a canned ACL, using the header x-amz-acl (case-insensitive), with the value bucket-owner-full-control.Ī constraint on this condition normally is used to ensure that the owner of the object (which is always the uploading user, not necessarily the owner of the bucket) can't create an object that the bucket owner is unable to read ("full control" is an unfortunate misnomer, because the bucket owner can already delete foreign objects, and despite this cannot further delegate permissions on the object).
