Raw Log Search user guide

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. For example, validating a configuration change or investigating a security alert.

3. (Optional) To limit the list of log sources, in the Filter field, enter the keyword or the name of a tag.

   See Log source tags for more information.

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 can group log sources by these tags:

• The role of the server or the type of device. For example, database server, web server, switch, router, access point.
• Location. For example, country, city, or site.
• Cluster name or high availability pair.
• Environment. For example, 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. Sign in to the Arctic Wolf Unified Portal.

2. Click Data Exploration > Raw Log Sources.

3. (Optional) To limit the list of log sources, in the Filter field, enter the keyword or the name of a tag.

5. Click the Select or Create a Custom Tag field, and then 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 a log source is missing firewall or Active Directory log sources and it does not have the related firewall or active directory tags, contact your CST at security@arcticwolf.com.

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