FAQ

• What security issues are being addressed in this release?
  • We are upgrading the encryption technologies for encrypting the data sent or received from the WebEx Cloud. This is an extension of the work we did in previous releases where we upgraded the technologies for encrypting the data stored in cloud. In addition, we have added a new mechanism for extending our encryption key rotation policies.
• Why does this change require a mandatory upgrade?
  • Newer meeting clients and Cisco applications have been updated with new encryption. The upgrade is required in order to ensure that all WebEx clients include the latest encryption technologies.
• I cannot upgrade by the requested deadline. Can I request an extension?
  • Due to nature of changes and Cisco’s commitment to keep all our customers secure we cannot extend this date. In order to help our customers achieve this date we are sending notice several months in advance.
  • Please contact your Customer Success Manager/Partner Success Manager for any further help.
• Is my site being exposed to any known vulnerabilities prior to the upgrade?
  • No. However; it is extremely important to update your site with all security enhancements, as soon as they are available
