Connect the IBM Security QRadar on Cloud data source to
the platform to enable your applications and dashboards to collect and analyze QRadar on Cloud security data. Universal Data Insights connectors enable federated search across
your security products.
Before you begin
Collaborate with a QRadar
administrator who can install the software on the QRadar Console, obtain the security token, IP address, and
other required information.
The IBM QRadar on Cloud
connector is designed to work with the Ariel event and flow data. Both event and flow data must be
enabled on QRadar. The connector requires that
the following content extensions are installed on your QRadar on Cloud environment:
If you have the previous versions of these content extensions, you must install the new
versions to update the extensions.If you have a firewall between your cluster and
the data source target, use the IBM Security Edge Gateway to
host the containers. The Edge Gateway must be
V1.6 or later. For more information, see Setting up Edge Gateway.
To conduct a federated search for domain names, you must add the DNS Request
Domain custom event property to the appropriate DSMs in QRadar. For more information, see Adding the DNS Request Domain custom event property to your DSMs.
About this task
Structured Threat Information eXpression (STIX) is a language and
serialization format that organizations use to exchange cyberthreat intelligence. The QRadar on Cloud connector uses STIX patterning to query QRadar on Cloud data and returns results as STIX objects. For more information about how the QRadar on Cloud data schema maps to STIX, see QRadar
STIX Mapping
(https://github.com/opencybersecurityalliance/stix-shifter/blob/develop/adapter-guide/connectors/qradar_supported_stix.md).
Procedure
- Go to
.
- On the Data Sources tab, click
Connect a data source.
- Click IBM QRadar and QRadar On Cloud, then click
Next.
- Configure the connection to the data source.
- In the Data source name field, assign a
name to uniquely identify the data source connection.
You can create multiple connection
instances to a data source so it would be good to clearly set them apart by name. Only alphanumeric
characters and the following special characters are allowed: - .
_
- In the Data source description field,
write a description to indicate the purpose of the data source connection.
You can create
multiple connection instances to a data source, so it is useful to clearly indicate the purpose of
each connection by description. Only alphanumeric characters and the following special characters
are allowed: - . _
- If you have a firewall between your cluster and the data source target,
use the Edge Gateway to host the containers. In
the Edge gateway (optional) field, specify which Edge Gateway to use.
Select an Edge Gateway to host the connector. It can take up to five
minutes for the status of newly deployed data source connections on the Edge Gateway to show as being connected.
- In the Management IP or hostname field, set the IP address of
the data source so that the platform can communicate with it. This information is required and
corresponds to the Management IP address value in the QRadar console.
- In the Host port field, set the port number that is associated
with the data source host. The port is 443 by default.
-
Set the query parameters to control the behavior of the search query on the data source.
- In the Concurrent search limit field, set the
number of simultaneous connections that can be
made to the
data source. The default limit for the number of connections is 4. The value must not be less than 1
and must not be greater than 100.
- In the Query search timeout limit field,
set the time limit in minutes for how long the query is run on the data source. The default time
limit is 30. When the value is set to zero, there is no timeout. The value must not be less than 1
and must not be greater than 120.
- In the Result size limit field, set the maximum
number of entries or objects that are returned by search query. The default result size limit is
10,000. The value must not be less than 1 and must not be greater than 500,000.
- In the Query time range field, set the time
range in minutes for the search, represented as the last X minutes. The default
is 5 minutes. The value must not be less than 1 and must not be greater than 10,000.
Important: If
you increase the concurrent search limit and the result size limit, a greater amount of data can be
sent to the data source, which increases the strain on the data source. Increasing the query time
range also increases the amount of data.
- Optional: If you need to customize the STIX attributes mapping, click
Customize attribute mapping and edit the JSON blob to map new or existing
properties to their associated target data source fields.
- Configure identity and access.
- Click Add a Configuration.
- In the Configuration name field, enter a
unique name to describe the access configuration and distinguish it from the other access
configurations for this data source connection that you might set up. Only alphanumeric characters
and the following special characters are allowed: - . _
- In the Configuration description field, enter
a unique description to describe the access configuration and distinguish it from the other access
configurations for this data source connection that you might set up. Only alphanumeric characters
and the following special characters are allowed: - . _
- Click Edit access and choose which users can
connect to the data source and the type of access.
- In the Authentication Token field, enter the unique identifier
of the data source that you want to establish the connection with.
To obtain an
authentication token:
- Go to https://www.ibm.com/support/home/.
- Open a support case. Specify the following details in the case: An Authorized Service token
needs to be generated. Include details on User Role and Security Profile.
Specify a user role
that is restricted to only Event and Flow viewing permissions. Specifically, the
Offenses, Log Activity, and Network
Activity roles. However, you can also choose All if you do not
want to create such a role. To follow best practice, do not select
Admin.
- Click Add.
- To save your configuration and establish the connection, click
Done.
You can see the data source connection configuration that
you added under Connections on the data source settings page. A message on the card indicates
connection with the data source.
When you add a data source, it might take
a few minutes before the data source shows as being connected.
Tip: After you connect a
data source, it might take up to 30 seconds to retrieve the data. Before the full data set is
returned, the data source might display as unavailable. After the data is returned, the data source
shows as being connected, and a polling mechanism occurs to validate the connection status. The
connection status is valid for 60 seconds after every poll.
You can add other
connection configurations for this data source that have different users and different data access
permissions.
- To edit your configurations, complete the following steps:
- On the Data Sources tab, select the data source connection that
you want to edit.
- In the Configurations section, click Edit
Configuration (
).
- Edit the identity and access parameters and click
Save.
What to do next
Test the connection by running a query with IBM Security Data Explorer. To use Data Explorer, you must have data sources that are
connected so that the application can run queries and retrieve results across a unified set of data
sources. The search results vary depending on the data that is contained in your configured data
sources. For more information about how to build a query in Data Explorer, see Build a query.
