The problem was that the root account used by systems administrators when reconfiguring parts of the system, was able to edit any of the audit trails created by the system. Freedman designed a new product, PowerBroker, that was similar in concept to today's sudo products, but which allowed centralized control and auditing of an entire network even down to the keystroke level, with the logs stored on a dedicated remote computer to which the system administrators typically did not have access.
The issue stemmed from the fact that the primary account used by system administrators for system modifications could alter any audit records generated by the system. To address this, Freedman created PowerBroker, which shared similarities with today's sudo products in its approach to centralized control and auditing across an entire network, including fine-grained monitoring of keystrokes, with logs stored on a dedicated server that system administrators typically did not have access to.
