How Can I Improve My Server Security
A few days ago some stupid Neighbour or so Hacked my AP, changed the Admin Password and deleted every Port-forwarding rule in it.
I repaired the Damage and looked at the log file on my Media-Server. This Guy really only Hacked my WiFi but on the Server logs are some Alarming lines. I use an Ubuntu 14.04 Server and I changed after that every standard Port and Password.
My Questions are,
- How can I better secure the Server against Attacks? (specially SSH )
- Can someone tell me please what is going on in my "auth.log"
No IP address in this file is one of mine.
Thanks for any Help!
