Abstract

The present invention provides rule sets and a system and method for creating and enforcing rule sets in a computer management system. Rules specifying a constraint on an attribute of a computer system may be created to enforce a policy. Multiple rules may be arranged into rule sets, specifying multiple constraints for a target computer system. Rules or rule sets are enforced against a target computer system to determine whether the rule or rules are satisfied. In the event an attribute of the computer system does not satisfy a constraint, the system declares the rule failed and may take action according to a severity attribute specified in the failed rule.

Claims

1. A method of creating a rule set, comprising:

selecting an attribute of a computer system;

specifying a constraint for the selected attribute; and

associating the specified constraint with the selected attribute.

2. The method of creating a rule set of claim 1, further comprising selecting a weight associated with the attribute and associating the selected weight with the rule set.

3. The method of creating a rule set of claim 2, wherein the selected weight specifies an importance value.

4. The method of creating a rule set of claim 1, wherein the attribute is a configuration parameter which is represented as a numerical value, and the constraint specifies at least one numerical value of the configuration parameter.

5. The method of creating a rule set of claim 4, wherein the attribute is a configuration parameter which is represented as a Boolean value, and the constraint specifies at least one numerical value of the configuration parameter.

6. The method of creating a rule set of claim 4, wherein the attribute is a configuration parameter which is represented as a Boolean value, and the constraint specifies a variable representing at least one numerical value of the configuration parameter.

7. The method of creating a rule set of claim 1, wherein the constraint is a variable.

8. The method of creating a rule set of claim 4, further comprising selecting a host target data set for the rule set and associating the selected host target data set with the rule set.

9. The method of creating a rule set of claim 1, further comprising setting a severity level for at least one rule within the rule set.

10. A method of enforcing a policy in a computer system, comprising:

selecting at least one rule associated with said policy;

applying said selected rule against configuration data associated against at least one target computer, the configuration data including attribute values; and

determining whether an attribute value specified in said applied rule and associated with the target computer satisfies the applied rule.

11. The method enforcing a policy of claim 10, further comprising:

determining the configuration data associated against at least one target computer from a rule set associated with the selected rule.

12. The method enforcing a policy of claim 11, further comprising:

determining whether there are additional rules in a rule set that have not been applied to configuration data associated against at least one target computer;

in the event at least one rule from the rule set has not been applied to the configuration data associated against at least one target computer;

selecting a rule from the rule set that has not been applied;

applying the rule selected from the rule set against configuration data associated against at least one target computer, the configuration data including attribute values;

determining whether an attribute value specified in said applied rule and associated with the target computer satisfies the applied rule; and

repeating the step of determining whether there are additional rules in a rule set that have not been applied to configuration data associated against at least one target computer until all the rules of the rule set are applied against configuration data associated against at least one target computer.

13. The method of enforcing a policy of claim 12, wherein the determination whether there are additional rules in a rule set that have not been applied to configuration data associated against at least one target computer is made by checking the rule sets associated with the policy being enforced.

14. The method enforcing a policy of claim 10, wherein the selected rule is selected from a rule set associated with said policy.

15. The method enforcing a policy of claim 10, further comprising:

determining whether the selected rule includes a variable constraint;

in the event the selected rule includes a variable constraint, determining where to retrieve the variable constraint; and

retrieving the variable constraint from the determined location.

16. The method enforcing a policy of claim 10, further comprising:

determining whether a weight is associated with the attribute of the applied rule; and

in the event a weight is associated with the attribute of the applied rule,

17. The method enforcing a policy of claim 10, further comprising:

in the event the attribute value specified in said applied rule and associated with the target computer does not satisfy the applied rule;

determining whether a severity attribute is associated with the applied rule; and

in the event a severity attribute is associated with the applied rule, taking action according to the severity attribute associated with the applied rule.

18. The method enforcing a policy of claim 10, wherein configuration data the selected rule is applied against is selected according to a configuration data selector associated with the applied rule.

19. The method enforcing a policy of claim 10, wherein the attribute is a configuration parameter which is represented as a Boolean value, and a constraint associated with said attribute specifies at least one numerical value of the configuration parameter.

20. The method enforcing a policy of claim 10, wherein a constraint associated with said attribute value is a variable, and wherein application of said selected rule includes retrieving the constraint variable from a specified location.
