Security Configuration Considerations on the FICO Analytic Cloud

The following information describes the security implications when using Xpress Executor on the FICO Analytic Cloud.

Xpress Executor operates in a secure configuration when deployed on the FICO Analytic Cloud. This secure configuration enforces a number of restrictions:

  • Solver algorithms are limited to 4 threads.
  • Module parameters can only be set in the model itself.
  • The python3 Mosel module ("python3.dso") is not available on the FICO Analytic Cloud.
  • mmjobs: routines connect and detach are disabled.
  • mmhttp: routine startsrv is disabled.
  • mmhttp: outgoing requests to IP addresses and domains in the FICO Analytic Cloud are disabled.
  • mmodbc: connection strings must be of the form DSN=<dsn> or use the integrated 'sqlite' driver.
  • mosjvm: Java classes will execute under a security manager to prevent access to files outside the Mosel work directory, starting sub-processes, accessing databases or network resources; For more, see the section Use in Mosel Restricted Mode of the Mosel to Java Module reference manual.
Note: These restrictions are in addition to the default rules:
  • NoExec (no system calls or interaction with external native code)
  • NoReadNoWriteWDOnly (file system access restricted to the current working directory only)
Covered Topics
  • Invoking R Scripts
    The release of R currently available for use with Xpress Executor on the FICO Analytic Cloud is version 3.2.2 and includes all the base and recommended R packages. Additional packages can be installed by calling the standard R function "install.packages()"; these will be cached for the duration of the Mosel/scenario execution.
