I can send logs to graylog server by providing specific details in my rsyslog file on the node.Something like this
*.* @logs.example.com:1337
My question is that if someone else also has this info regarding my graylog server,that person can also send logs to my graylog server.
How can i ensure that logs that i am receiving are only from my server and someone else do not use this information. I.e some king of authentication at node end to send the logs.
