Sample Use Case: Single Central Log ServerΒΆ

We have a quite simple use case. There is one central syslog server, named These server is being reported to by two Linux machines with name and Also, there is a third client - - which send both its own messages to the central server but also forwards messages receive from an UDP-only capable router. We have decided to use because it is in the same local network segment as the router and so we enjoy TLS’ security benefits for forwarding the router messages inside the corporate network. All systems (except the router) use rsyslog as the syslog software.

Please note that the CA must not necessarily be connected to the rest of the network. Actually, it may be considered a security plus if it is not. If the CA is reachable via the regular network, it should be sufficiently secured (firewal rules et al). Keep in mind that if the CA’s security is breached, your overall system security is breached.

In case the CA is compromised, you need to regenerate the CA’s certificate as well as all individual machines certificates.
