This small guide will help you to increase the security of your raspberry and transform it in a 24×7 running server.
Security in place
Here a small check list with external references:
- Change pi password.
- Disable SSH Password Authentication and Root Login. Root login should be already disabled on recent distributions.
- Consider installing remote logging. Siemless is a cloud based service which will load all you logs via a vpn, and provide a raspberry-pi guide too.
- Configure a firewall
For ease of use, I suggest putting in place webmin:
apt-key add jcameron-key.asc
apt-get install webmin
