Your Grafana Loki setup needs security and access control


↺ Your Grafana Loki setup needs security and access control


> The direct reason that you want access control for Loki is that Loki provides direct access to your logs, in full and basically raw form. All of your logs, from all of the systems that you're having feed in to Loki, with all of the potentially sensitive information that might be appearing in them. In many situations, you don't want to provide this sort of log access to everyone internally and you would be much more restrictive about who had access to read the logs on, say, a central syslog server. This applies both to direct access to Loki's HTTP API endpoints and to access to Loki through, say, Grafana's 'Explore' ad-hoc query system (which is a convenient way to poke through your Loki logs in a browser, instead of using LogCLI to do it from the command line).

> iblock is simple, if you connect to any port on which it's listening, you get banned in the firewall.
