  • Implementing automatic access control list validation using automatic categorization of unstructured text
    Patent number: 8739279
    Abstract: A method, system and computer program product are provided for implementing automatic access control list validation using automatic categorization of unstructured text. Automatic categorization of unstructured text is performed on a plurality of documents of an access control list for determining an average term vector. Each of the documents is scored against the average term vector to identify a dissimilar document, flagged as a possible security risk. Automatic categorization of unstructured text is performed on user information of a plurality of members of a candidate access control list for determining a typical term vector. A similarity score is determined by user information and the typical term vector, members of an access control list that are dissimilar from other members of the access control list are identified.
