Raw Log Search

Raw Log Search is a licensed Managed Detection and Response (MDR) add-on feature that lets you search the Arctic Wolf platform, which stores an aggregation of raw log data from your on-premises systems and cloud services. This feature allows you to retrieve logs in raw format for operational and security-related tasks, such as validating a configuration change or investigating a security alert.

Log source tags

Tags are a convenient way to organize your log sources for future searches. You can create custom tags to group log sources. For example, you might group log sources by:

• The role of the server or the type of device, such as, database server, web server, switch, router, access point.
• Location, such as country, city, or site.
• Cluster name or high availability pair.
• Environment, such as, development, test, or production.
• Cost center, business unit, or department.

There are also system-assigned tags that you use to refine your search. These tags are automatically assigned to your log sources based on the parser configured in the Arctic Wolf system.

Tags are listed in the Assigned Tags column.

Add a tag to multiple log sources

1. From the Arctic Wolf Unified Portal menu bar, Data Exploration > Raw Log Sources.

2. (Optional) To narrow the list of log sources, enter the keyword or the name of a tag in the Filter box.

   Tip: See Log source tags for more information.

3. Select the log sources that you want to tag.

4. Click the Select or Create a Custom Tag field to enter the name of a new custom tag or select an existing custom tag.

   Note: You cannot manually add a system-assigned tag to a log source. If there are log sources that are missing firewall or Active Directory log sources that do not have the respective firewall or active directory tags, contact your CST.

5. Click Add Tag.

The custom tag appears in the Assigned Tags column for the log sources that you selected.

Remove a tag from multiple log sources
