Classification: CPC G | IPC G

Claim 4:
5. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions being executable by one or more processors to cause the one or more processors to perform operations comprising:
identifying related data tables within a set of data tables within a database using principal component analysis, wherein the principal component analysis is based on a frequency of co-occurrence within the set of data tables and another frequency of co-occurrence of communication networks accessing data within the set of data tables, and wherein the related data tables have co-occurring principal components above a co-occurrence threshold;
identifying a set of related data types within the related data tables;
determining a set of similarities among the set of related data types;
mapping the related data types based on the set of similarities; and
based on the mapping, restructuring one or more data tables of the set of data tables to generate a restructured data table, wherein the restructuring alters a column position, a data table position, and a row position of the one or more data tables;
comparing the set of related data types to a current security policy;
based on the mapping and the restructuring, modifying the current security policy by:
identifying a policy condition linked to at least one related data type, the policy condition monitoring a first field within a data table of the set of data tables; and
modify the first field to a second field within the current security policy, the second field associated with the at least one related data type in the restructured data table; and

updating a monitored field list based on the restructured data table, wherein the monitored field list comprises a set of fields respectively associated with the related data types.
