Configure Sharing for Netskope and STIX/TAXII
  1. Go to Threat Exchange and select Sharing. The Sharing page displays the existing relationships for each sharing configuration in grid view as shown below. The Sharing page also has inputs to configure new sharing from one plugin to another.

  3. Select a Business Rule, and then select Netskope for the Destination Configuration. Sharing configurations are unidirectional. data obtained from one plugin is shared with another plugin. To achieve bi- or multi-directional sharing, configure each separately.

  4. Select a Target. Each plugin will have a different target or destination for the IoC.

    Depending on the Target selected, Add to URL List or Add to File Hash List, the remaining options change. If using a File Hash List, jump to the next step.

    For a URL List, select a List Name, enter a New List Name. The List Name must exist in the Netskope UI. For information about creating a URL List, refer to Add a URL List. Now select a URL List Type, and then a List Size and Default URL.

  5. For Add a File Hash List, enter a List Name, List Size, and Default File Hash. The List Name needs to exist in your Netskope UI at Settings > Policies > Profiles. For information about creating a File Profile for hashes, refer to Adding a File Profile

  6. Click Save.

  7. Repeat steps 2-5, but select Netskope as the Source Configuration and STIX/TAXII as the Destination Configuration.

  8. Click Save.

Adding a new sharing configuration on the active source poll will share the existing IoCs of the configuration to the destination configuration. Whenever a new sharing configuration is built, all the active IoCs will also be considered for sharing if they match the source/destination combination.

Note

Plugins that do not have API for ingesting data cannot receive threat data. This is true of the installed plugin API Source, which provides a bucket associated with an API endpoint for remote 3rd-party systems to push data to. Once a Sharing policy has been added, it takes effect.

After a sharing configuration has been created, the sharing table will show the rule being invoked, the source system providing the potential IoC matches, the destination system that will receive matching IoC, and the target applicable to that rule. Multiple Sharing configurations can be made to support mapping certain IoC to multiple targets even on the system destination system.

Modify, Test, or Delete a Sharing Configuration

Each configuration supports 3 actions:

  • Edit the rule by clicking on the pencil icon.

  • Test the rule by clicking on the synchronization icon. This tests how many IoC will actually be sent to the destination system based on the timeframe and the rule.

  • Delete the rule by clicking on the garbage can icon.
