I'm testing Graylog2 as our central log management tool for our applications. Is there a way to secure the log submit process?
If we only use graylog2 in our local environment its not a big deal to secure the submit process through some firewall rules, e.g. only accept network traffic from internal ip subnets, but is there a way for public clients to authenticate against graylog2 and submit only if for example a login-token is submitted through the log.
In short: Is there a way to protect a graylog2 server against spam logs?
