Cisco Duo Log Sync (DLS)

Duologsync (DLS) is a utility written by Duo Security that supports fetching logs from Duo endpoints and ingesting them to different SIEMs.

A logging filepath can be specified in config.yml. By default, logs will be stored under the /tmp folder with name duologsync.log.

These logs are only application/system logs and not the actual logs retrieved from Duo endpoints.
