Abstract: A tokenization system tokenizes sensitive data to prevent unauthorized entities from accessing the sensitive data. The tokenization system accesses sensitive data, and retrieves an initialization vector (IV) from an IV table using a first portion of the sensitive data. A second portion of the sensitive data is modified using the accessed initialization vector. A token table is selected from a set of token tables using a third portion of the sensitive data. The modified second portion of data is used to query the selected token table, and a token associated with the value of the modified second portion of data is accessed. The second portion of the sensitive data is replaced with the accessed token to form tokenized data.

Abstract: Database entries can be protected by indexing the entries using a plurality of indexes, each associated with a level of access rights. A level of access rights can be determined from a search query, and an index can be selected based on the determined level of access rights. A search key can be generated based on the received query, and the selected index can be searched using the search query. Database entries mapped to the values of the selected index returned in response to the search can be outputted. Each index is associated with a different granularity defining the number and/or ambiguity of search results returned in response to searching an index.

Abstract: A cooperative processing and escalation method and system for use in multi-node application-layer security management is disclosed. The method includes the steps of identifying individual application security nodes, grouping and configuring nodes for cooperative processing, assigning the default operational mode at each node, assignment of logging and alert event tasks at each node, and defining escalation and de-escalation rules and triggers at each node. Both loosely-coupled and tightly-coupled configurations, each with its cooperative processing model, are disclosed. The method includes provision for central console configuration and control, near real-time central console dashboard operations interface, alert notification, and operator override of operational modes and event tasks.
