Patent number: 10348768Abstract: Training a random forest model to relate settings of a network security device to undesirable behavior of the network security device is provided. A determination of a corresponding set of settings associated with each region of lowest incident probability is made using a random forest. The plurality of identified desired settings are presented as options for changing the network security device from the as-is settings to the identified desired settings. A choice is received from the plurality of options. The choice informs the random forest model. The random forest model ranks for a new problematic network security device the plurality of options for changing the new problematic network security device from as-is settings to desired settings by aggregating an identified cost of individual configuration changes, thereby identifying a most cost-effective setting for the network security device to achieve a desired output of the network security device.Type: GrantFiled: March 9, 2017Date of Patent: July 9, 2019Assignee: International Business Machines CorporationInventors: Rhonda L.

Patent number: 10074055Abstract: In an approach to assisting database management, a computer generates one or more combinations of values of one or more database configuration parameters. The computer associates each of the one or more generated combinations of values with an incident probability. The computer defines relationships between the one or more generated combinations and the associated incident probabilities. The computer stores the defined relationships into an object representable as a multi-dimensional matrix, whose dimensions correspond to a plurality of database configuration parameters used to generate the combinations of values. The computer traverses the object to identify a path in the matrix. The computer returns the identified path for enabling subsequent interpretation thereof as a rule for passing from a first database configuration, corresponding to the first one of the one or more generated combinations, to a second database configuration, corresponding to the second one of the one or more generated combinations.Type: GrantFiled: July 29, 2015Date of Patent: September 11, 2018Assignee: International Business Machines CorporationInventors: Jasmina Bogojeska, Ioana Giurgiu, George E.

Publication number: 20180174069Abstract: A computer-implemented method of increasing reliability of an information technology environment comprising a plurality of hardware devices. Training data is received and a random forest is built from the training data using machine learning. A particular hardware device in the plurality of hardware devices is determined to be strange. Strange is defined as the particular hardware device having a proximity value lower than a predetermined threshold value for the random forest. A preventative action is determined to lower a risk of failure of the particular hardware device. The preventative action is reported. Reporting includes at least one of displaying a report on a display device, printing the report onto paper, and storing the report in a non-transitory computer recordable storage medium.Type: ApplicationFiled: December 15, 2016Publication date: June 21, 2018Inventors: Rhonda L.
