Background

Cisco evaluates Microsoft security updates for potential impact to Cisco Customer Contact Business Unit (CCBU) products. The qualification process results in one of four categorical ratings being applied to a given update: Impacting, Not Impacting, Deferred, or Not Applicable.

The four ratings are defined as follows:

1. Impacting (CCBU product impact testing is performed within a predefined window of when the security update is released by Microsoft)

   • The update is labeled by the vendor as Critical or Important or is otherwise of special interest to CCBU customers

   • It potentially affects some Contact Center component or functionality (or is basic to the OS and affects all operations for any software)

   • It must apply to the latest CCBU specified Service Pack(s)

2. Not Impacting (CCBU products are not impacted by the security update and no further testing is performed)

   • The update is labeled by the vendor as Critical or Important or is otherwise of special interest to CCBU customers

   • It does not affect any CCBU component or functionality or any basic OS functionality

   • It must apply to the latest CCBU Specified Service Pack(s)

3. Deferred (Validation is typically deferred to the next Service Release, Maintenance Release, and subsequent Major/Minor Releases)

   • The update is labeled by the vendor as Moderate or Low

   • It affects some CCBU component or functionality (or is basic to the OS and affects all operations for any software)

   • It must apply to the latest CCBU Specified Service Pack(s)

4. Not Applicable (The security update does not apply to any current CCBU product. No further qualification is required)

   • The security update does not apply to the latest CCBU Specified Service Pack(s), regardless of CCBU Enterprise product applicability or vendor-rated severity.
