Syslog

Scanner supports Syslog, which is a standard protocol used for message logging in various systems, especially in network devices and Unix/Linux-based systems. Many security tools emit Syslog data.

In order for Scanner to receive Syslog events, you need to configure a worfklow to push these logs to an S3 bucket that Scanner is linked to.

Step 1: Publish to S3

We recommend running Fluentd to receive Syslog data over the Syslog protocol and forward it to your S3 bucket, writing output files in JSON format.

You can follow the Fluentd documentation to configure it to receive Syslog input and write output logs to your S3 bucket. Make sure to configure the output format to be JSON. See the following Fluentd articles:

• Fluentd syslog input module

• Fluentd s3 output module

When you configure your syslog input module, in the parsing section, make sure to set keep_time_key to true so that Fluentd adds a time field to your log events. See: Fluentd syslog parser module - keep_time_key.

Step 2: Ingest via Scanner Collect
