Abstract
Guard tables including absence information are used in a security system to limit the processing of negative queries. A key corresponding to a request to access a network resource is hashed and the output of the hash is a bit position in a guard table. The bit value at the bit position in the guard table is checked to determine if the information to which the key corresponds is absent from a datastore. Further processing of the request can be based on the indicated presence or absence information.
