Data correlation lets you establish an association between the data fields in the imported data and the CCS data. By means of correlation, you ensure that CCS is able to consume the data that is imported from an external system. You must correlate data for assets, status and assessments.
In asset correlation, you associate assets in the external data system with assets in CCS. For example, you can correlate assets in external system using the following fields: Host name, IP address, and Fully qualified domain name. For adding new assets to CCS, See Reconciling assets based on external system data.
In status correlation, you associate assessment results in external data system with status in CCS. For example, external systems produce results in different formats such as closed, open, or range 0 to 5, which must be mapped to CCS formats of pass, fail, unknown and not applicable.
In assessment correlation, you provide assessment information to identify assessments in external data. For example, in external data, the Assessments name field contains the assessment name as password length. You must provide this assessment name field to CCS for identifying the assessments in external data.
To correlate external system data with CCS
Go to Manage > External Data Integration.
From the External Data Systems list, select a data system and then do one of the following:
From the taskbar, select System Tasks > Correlate Data With CCS.
Right-click the data system and then select Correlate Data With CCS.
In the Correlate Asset Data panel, in the Asset category section, select one of the following options:
CCS hosted assets (Identified by IP Address)
Other CCS assets
In the Correlate Status with CCS Results panel, in the Status field drop-down list, select the status field.
The Status fields appear in the Status field drop-down list only if you have selected the status and assessment fields while creating the data schema.
Click Add to add the status field to CCS results mapping, and then do the following:
In the Status values from external data column, type the value for the result data field in the imported data.
In the CCS Result Values drop-down list, select the CCS result value. The CCS Result Values drop-down list contains the following fields: Pass, Fail, Unknown, and Not Applicable. Map all the possible values in the Status field from external data. CCS represents all the values from external data as mapped CCS result values.
Perform this step only if you have selected the CCS status field in 6.
In the Select Assessment Information for Policy Compliance panel, specify the following information:
Assessment name field
Assessment message field
Click Next, and then on the Summary of Correlation of data with CCS panel, click Finish.
