Hi Team

Am looking to create outbound rule  from firewall to the GCTI IP.  So using the below lines in my rule as suggested by the SECOPS. Expecting your support on this for better understanding.
 

   $feed.graph.metadata.entity_type = "IP_ADDRESS"

    $feed.graph.metadata.product_name = "GCTI Feed"

    $feed.graph.metadata.source_type = "GLOBAL_CONTEXT"


 1. I would like to know how to validate the above lines and its values. If i do the UDM search i can able to see the   graph.metadata.source_type = "DERIVED_CONTEXT" and not the graph.metadata.source_type = "GLOBAL_CONTEXT"

  1. Since i have the source type : Mandiant Threat Intelligence. (Refer : Below Snap-2) 
    3. How i can confirm GCTI feeds are integrated.
    4. Is the feeds are updated at any frequency or feeds are updated live.
    Snap:1
  2. Snap: 2

For information on the www.virustotal.com IP address take a look at this blog post.  If you take a look in the same docs page from your screen shot on the left margin go down to Investigate a GCTI Alert to get details on how to identify GCTI alerts in the Alerts and IOCs page.
