CM-6 CONFIGURATION SETTINGS• Establishes and documents mandatory configuration settings for information technology products employed within the information system using Organization-defined security configuration checklists that reflect the most restrictive mode consistent with operational requirements;• Implements the configuration settings;• Identifies, documents, and approves exceptions from the mandatory configuration settings for individual components within the information system based on explicit operational requirements;• and Monitors and controls changes to the configuration settings in accordance with organizational policies and procedures.

  11. 11. One task = One job with Matching Server name
  12. 12. Match Task to ResultsTaskServer ‘SV-SERV1-TDP’ was O.K. with 100 Passed

  14. 14. Trending – CIO Level ReportMagnus CIO Level reports missed the point did not easily answer the question“Are we doing better?”We developed general trending info that showed at the CIO level we were movingIn the right direction…Once the “number of servers” “Flatlines”, we hope to see a general increase in percentcompliance over time.
  15. 15. Reporting Requirements [Adding a server]Adding a ServerWhenever a server is commissioned for production, the NIST Security Checklist Compliance Manager orIT Services shall enter the server into Secutor Magnus and the associated scheduling and reporting toolsand conduct an initial manual scan and verify the scan produced reasonable results. Once this is complete,they will inform the administrator and the DCIO that the scan results are ready to be reviewed. The DCIOand the administrator shall review[1] the results of the scan, comparing the percent compliance forany product instances on the server to the overall percent compliance for the product, taken overall current instances of the product. Commissioning a server that will reduce overall percent compliancefor any product requires approval of the CIO.[1] See Compliance Trending Application, menu “Report” > “CIO Reports” > “servers compared to profile”
  16. 16. Review compliance of a server Review of Compliance for a Server Whenever the configuration of a server changes, the DCIO shall review the percent compliance for all product instances measured in the scan taken after the change to the latest previous measure of percent compliance for each instance.[1] Should percent compliance be reduced, the DCIO shall report this to the ISSO as a compliance incident [1] See Compliance Trending Application, menu “Report” > “CIO Reports” > “Compare to last snapshot”
  17. 17. Monthly Review of Overall Percent Compliance Monthly Review of Overall Percent Compliance Each month, DCIO shall review the history of overall percent compliance for all products included in the NIST Security Checklist Scanning process[1]. Should there be a reduction in overall percent compliance for any product, the DCIO shall notify the ISSO and CIO that a compliance incident exists. [1] See Compliance Trending Application, menu “Report” > “CIO Reports” > “Profile Summary”
  18. 18. SchedulingMagnus could only schedule on:Day:Week:Month Day: We wanted to schedule based on “Tier” … So we “Inactivitiated” all magnus runs, And set them to run everyday, then we made them “Active” based on the tier …
  19. 19. Reviewing the Results
