Raw Event Filters
Filter out events before they're parsed by a log schema
Overview
Raw event filters let you define conditions under which to filter out ingested events. They act on raw data before it is parsed by a log schema, and can be defined using regex expressions or substrings patterns.
Once you have enabled a raw event filter, monitor its performance by viewing filtered event metrics.
Types of raw event filters
There are currently two types of filters:
Regex filters: Events that match the regex expression will be dropped.
Regex filters use Google's RE2 engine.
Substring filters: Events that include the pattern at least once will be dropped.
How to create a raw event filter
Raw event filters are applied on unparsed events—not normalized data, like that which is visible in the data lake. Ensure you are constructing filters based on raw data. Basing a raw data filter on normalized data could cause false positives and unintentionally dropped data.
To create a filter for parsed events instead, see Normalized Event Filters.
To create a raw event filter:
In the left-hand navigation bar of your Panther Console, click Configure > Log Sources.
Click the name of the log source you'd like to add a filter to.
Click the Filters tab.
A new filter form will be expanded. Configure the filter:
Click Condition, and select one of the options below. Learn more about the different ways to construct exclusion statements in Types of raw event filters.
Matches Regex
If you selected the Matches Regex condition, enter a regular expression. If you selected the Contains condition, enter a string value.
In the Quick Test section, enter a raw event to test against the filter you just created.
Click Run Test.
Notice whether the test event matches the exclusion pattern.
The filter is enabled by default. If you would like to disable it, click the Enabled toggle.
In the upper-right corner, click Save.
Enabling or disabling a raw event filter
After an ingestion filter has been created, you can enable or disable it:
In the left-hand navigation bar of your Panther Console, click Configure > Log Sources.
Click the name of the log source you'd like to enable or disable a filter on.
Click the Filters tab.
