Abstract

Claims (19)

1. A method, comprising:

determining, by a processor, that a portfolio comprising a plurality of entities is missing a portion of entity data for at least some entities in the portfolio, wherein the entity data is indicative of entity attributes;

synthesizing the missing portion of the entity data at least in part by:

determining a ratio of entity types of the plurality of entities in the portfolio at least in part by determining groupings of entities in the portfolio on a percentage basis;

locating one or more substitute entities that have substitute entity data that corresponds to the missing portion of the entity data at least in part by determining, based at least in part on the determined ratio of entity types, portfolios with similar ratios that have complete entity records; and

replacing the missing portion of the entity data with substitute entity data of the one or more located substitute entities;

locating clusters of similar entity data shared between two or more of the plurality of entities at least in part by comparing, by the processor, a combination of the entity data and the synthesized missing portion of the entity data for each of the plurality of entities to each other;

assessing a likelihood of a cyber security failure in a computer network of an entity of the plurality of entities based at least in part on the combination of the entity data and the substitute entity data; and

based at least in part on the assessing of the likelihood of the cyber security failure in the computer network of the entity, determining a set of computer network changes to reduce the likelihood of the cyber security failure in the computer network of the entity, the set of computer network changes comprising at least one of a change in a content delivery network (CDN) provider or a change in a cloud service provider.

2. The method of claim 1 , wherein the synthesizing of the missing portion of entity data comprises:

comparing the plurality of entities of the portfolio that is missing a portion of the entity data to entities with complete entity data; and

generating a synthesized portfolio, the generating comprising:

selecting the entities with complete entity data;

based at least in part on the comparison of the plurality of entities of the portfolio that is missing a portion of the entity data to entities with complete entity data, replacing the plurality of entities that is missing a portion of the entity data with the selected entities with complete entity data; and

wherein the entities with complete entity data are within additional portfolios that are similar in entity composition to the synthesized portfolio.

3. The method of claim 2 , further comprising substituting entity data, from the selected entities having the complete entity data, for the portion of the entity data that is missing, such that a likelihood of a cyber security failure for the synthesized portfolio mimics a likelihood of a cyber security failure of other similar portfolios.

4. The method of claim 2 , further comprising based on the synthesized portfolio, generating another synthesized portfolio and calculating a diversity score.

5. The method of claim 4 , further comprising creating, based at least in part on a set of resynthesized portfolios, a range of diversity scores.

6. The method of claim 1 , further comprising automatically recommending, based on the assessed likelihood of cyber security failure, at least some of the determined set of computer network changes.
