ACL’s vs. Mainframes

In the year 2000, %60-80 of business data, sensitive fiduiciary data, and otherwise banking information was and is stored on legacy systems known as mainframes. These systems are built upon flat-file database schemes and were obsolete by the 1980’s because of their large size and the advent of the PC personal computer. However, these systems are largely in use by insurance companies, banks, and financial industries for the sake of change management and the largely institutionalized practices employed by these systems. Despite their widespread use, mainframes have a well-known security breach related to passwords and proportional access to ancillary data that is unnecessary. ACL’s, however, are a newer standard of authentication that limits access up to one data-field whereas mainframes give an entire population view for one retrieval.

    the beauty of acl’s in online web publishing is likewise simple. not only are specific fields of data restrictable to specific users but also access control entries can manage groups of sub-fields of a population. just imagine giving advertisement style access of your blog/hr info profile to all: 1) single women in your area code, 2) age 24-49, 3) that drive a red pickup. cms users matching these criteria could receive the data via search or subscription to these data sub-groups. regardless, a specious style of auditing could do away with the scope of mainframe authentication but acl style data management is much more extensible.
