What to do before connecting Ubuntu Server to the internet for the first time?
- by CodeMonkey
I just finished installing Ubuntu Server 12.10 on an Asus Eee PC 1000H (to be used as a home server/sandbox) from USB. I installed this software during installation:
OpenSSH server
LAMP server
Samba file server
Virtual Machine host
I won't use 2, 3 or 4 for a while though. Can/should I turn these off somehow?
I have turned home directory encryption on.
Security updates are installed automatically.
I have chosen a strong password for the single user.
I have never plugged in the internet cable so far. Before doing so I'd like to ask:
What can/should I do/install to increase security before connecting to the internet?
Firewall? Fail2ban? Users/Passwords? Encryption? Enable/Disable functionality? etc.
I'm sorry if you get this question a lot. I've searched around quite a while, but it still feels like I might overlook something important.
