Carbon Black App Control (formerly Cb Protection)

Issue/Introduction

What to expect when running the server environment is disconnected or has no internet access

Environment

  • App Control Server (formerly CB Protection): All Supported Versions

Resolution

 Without opening an outbound connection to services.bit9.com (Cb Collective Defense Cloud) either directly or via a proxy,  the following functionalities will not work:

  • Trust scores on hashes
  • Trust scores on publishers
  • Threat scores on hashes
  • Updated ATIs (Advanced Threat Indicators)
  • Updated Updaters and Rapid Configs
  • Updated System Health Indicators
  • Certificate revocation checks using external data sources
Otherwise the product will work normally.

Additional Information

  • App Control is not depending upon internet connectivity and works perfectly fine in network-isolated environments (as long as the agents and server can communicate); Enforcement, policies and software rules will still be able to function.
  • The server upgrade procedure does not change in an isolated environment.
