Abstract
Activity data is analyzed or evaluated to detect behavioral patterns and anomalies. When a particular pattern or anomaly is detected, a system may send a notification or perform a particular task. This activity data may be collected in an information management system, which may be policy based. Notification may be by way e-mail, report, pop-up message, or system message. Some tasks to perform upon detection may include implementing a policy in the information management system, disallowing a user from connecting to the system, and restricting a user from being allowed to perform certain actions. To detect a pattern, activity data may be compared to a previously defined or generated activity profile.
Claims20
A method of managing information of a system comprising:
- providing a plurality of information management rules;
- providing an activity database;
- gathering activity data from a first target in the activity database;
- gathering activity data from a second target in the activity database, wherein the first target is a different entity from the second target;
- associating at least a first rule of the plurality of information management rules to the first target;
- evaluating the gathered activity data from the first and second targets according to a detection algorithm, wherein the detection algorithm detects at least one of:
- a first condition comprising the first target has attempted to access a unit of information more than X1 times in a Y1 time period;
- a second condition comprising the first target has attempted to access more than X2 units of information in a Y2 time period;
- or
- a third condition comprising the first target has an aggregated usage time in a program above a time value X3 in a Y3 time period;
- based on the detection algorithm, determining at least one of the first, second, or third conditions occurring, associating an additional second rule to the first target;
- and
- for the first target, controlling usage of information based on the at least first rule of information management rules and the additional second rule, wherein the controlling further comprising:
- for a first activity at the first target, evaluating whether the at least first rule of information management rules applies based on the first activity;
- and
- for the first activity at the first target, evaluating whether the additional second rule applies based on the first activity, wherein the additional second rule comprises a first abstraction, the first abstraction is defined in a first definition statement stored separately from the additional second rule and the first abstraction, and the evaluating whether the additional second rule applies comprises:
- retrieving the first definition statement;
- when evaluating the second rule, replacing the first abstraction of the additional second rule by the first definition statement;
- and
- evaluating the additional second rule with the replaced first definition statement.
