Various embodiments are generally directed to techniques for generating updating, and/or validating one or more aspects of an access policy for a data bucket, such as based on usage data corresponding to the data bucket, for instance. Some embodiments are particularly directed to automatically generating, updating, and/or validating an access policy for a data bucket based on analysis of log data corresponding to the data bucket. In some embodiments, log data comprising access records to a data bucket may be analyzed to determine access requirements for a set of entities. In some such embodiments, the access requirements for the set of entities may then be used to generate an access policy for the data bucket.
