Configuring intrinsic analysis to be performed locally using the CLI

Prev Next

This procedure describes how to use CLI commands to configure the Intelligent Virtual Execution - Server appliance to perform intrinsic analysis locally on the appliance. Malware intrinsic analysis is performed in the DTI cloud by default. You can change the location where malware intrinsic analysis occurs by using CLI commands only.

When intrinsic analysis is performed from the DTI cloud with a two-way content license, objects are analyzed and compared against a larger set of known malware families. The compute node can upload malware samples to the DTI network for analysis with a two-way content license.

When intrinsic analysis is performed locally on the Intelligent Virtual Execution - Server appliance with a one-way sharing content license, malware samples will not be submitted to the DTI cloud.

Note

You can configure intrinsic analysis only using the CLI.

Prerequisites
  • Operator or Admin access

  • A one-way sharing CONTENT_UPDATES license is installed on the Intelligent Virtual Execution - Server appliance. Run the show licenses command. The command output must include the following line for the CONTENT_UPDATES license information:

    Sharing:          all (ok)

    Example:

    hostname (config) # show licenses
    License 1: LK2-CONTENT_UPDATES-1111-1111-1111-1111-1111-1111-1111-1111-1111-1111-1111-1111-1111-1111
    Feature:          CONTENT_UPDATES
       Description:      Content updates
       Valid:            yes
       Start date:       2016/05/03 (ok)
       End date:         2017/05/03 (ok)
       Tied to appl ID:  0CC47A31C5F8 (ok)
       Sharing:          all (ok)
       Active:           yes
      
       License 2: LK2-FIREEYE_APPLIANCE-2222-2222-2222-2222-2222-2222-2222-2222-2222-2222-2222-2222-2222-2222-2222-2222-2222-2
       ...
  • Static analysis is enabled on the Intelligent Virtual Execution - Server appliance. Check the "Static Analysis enabled" field in the output of the show static‑analysis config command.

  • Download and install the latest security content with the new malware samples.

    Use the fenet security-content apply-update command.

To configure the Intelligent Virtual Execution - Server appliance to perform intrinsic analysis locally:
  1. Go to CLI configuration mode.

    vx-hostname > enable
    vx-hostname # configure terminal
  2. Configure the Intelligent Virtual Execution - Server appliance to analyze objects locally for intrinsic analysis.

    vx-hostname (config) # malware-intrinsic-analysis local

    If intrinsic analysis is disabled, the command output displays the following message:

    % Malware Intrinsic Analysis(MIA) is currently disabled. Cannot change MIA configuration. Please enable MIA to change configuration.
  3. Verify the local status of intrinsic analysis.

    vx-hostname (config) # show static-analysis config
     
      Static Analysis enabled                : yes
        AV-suite enabled                     : yes
        AV-check enabled                     : yes
        Dropper enabled                      : no
        YARA enabled                         : yes
        Malware Intrinsic Analysis enabled   : yes (local)
      Embedded object extraction enabled     : no
      Static info policy                     : Disable
     
      Yara Configuration
        Yara policy                          : both
        Yara customer match limit            : 5
        Yara customer default weight         : 0
     
      Malware Whitelist Past Hours           : 24
      Malware Blacklist Past Hours           : 4
      Analysis reset duplicate since         : 2016/07/07 22:46:16
