If you don't have Internet connectivity on the machine you're using to install and configure Security Analysis Solution (SAS), then follow the instructions in this document to get up and running.

Errors during Initial Configuration

When you install SAS, the initial configuration starts a number of download tasks. These will fail on a machine that is not connected to the Internet, resulting in log errors like the following:

Description: Exception downloading file C:\ProgramData\Arellia\ScapContent\nvdcve-2.0-2002-2006_NVD CVE v2.0 - 2002-2006 (98a6f6d7-aa55-4536-be45-86de0725726e)\nvdcve-2.0-2002-2006.zip from http://portal.arellia.com/data/scap/nvdcve-2.0-2002-2006.zip.

This error message shows you the URLs of the profile content that you can access on a connected machine to download various .zip and .xml files. 

There are also a number of SCAP Data Sources that are registered by default. You must download these on a machine that is connected to the Internet, copy them to the correct folders on the AMS, and then re-run the registration tasks that failed during the initial configuration as described previously.

 

If downloading the content manually, get the content (typically .zip files) from the locations specified above and carry to the AMS  Then unzip to the %ProgramData%\Arellia\ScapContent.  The zipped content should create its own folder under the ScapContent folder and place any files and sub-folders in that directory.

    • Note:  most content comes from external sites to Arellia; typically nist.gov.  The checklist and some of the CVE data comes from portal.arellia.com.  This can be seen by searching arellia-checklist-1.4.xml for portal.arellia.com.
  • Re-run each of the "XXX Update tasks" by right clicking on each of the failed task runs and choosing Start Now. There are 10 of these tasks to run. See the following screen shot showing where these tasks can be found.

Importing Profiles

Running the console and choosing the Profiles tab will take you to the Download Profiles view. It will look like the following:

The download profiles page shows the links but they will fail to import. You need to perform the downloads on a system that does have internet access and then copy the downloaded files to a location accessible from your Arellia Console. Once the files are available you then use the Import Profile action on the Profiles tab (bottom left). Choose the profile content file and import.

  • There is a page on the Arellia Data Portal that shows these links. See View Arellia Checklist. Or you can go direct to the various official sites.
  • To set expectations - profile imports can take a while, whether connected to the internet or not - on the order of an hour for a handful of profiles.

 

To install arellia-checklist-1.4.xml, either download it from http://portal.arellia.com/data/scap/arellia-checklist-1.4.xml, or download it on a machine that is connected to the Internet and then copy it from the program data folder C:\inetpub\wwwroot\Ams\App_Data\SAS\ScapChecklists. Then click Try Again and you'll see the list of available checklists.
