Enable the fail2ban service so that it starts at boot:<br />

== Configuration == <br />
*Configuration files are located at /etc/fail2ban<br />

===Alpine new sshd key filter===<br />
*Out of the box, alpine comes with /etc/fail2ban/filter.d/alpine-sshd.conf, that protects from password failures and additional ddos protection /etc/fail2ban/filter.d/alpine-sshd-ddos.conf<br />
*But, if you turn off PasswordAuthentication in /etc/ssh/sshd_config, the above filters won't work<br />
*There are opinions against the utility of fail2ban: <s>''Fail2ban is fundamentally a wrong answer to the problem. If you're taking the time to install such things, you should instead either be turning off password authentication (relying only on keys)'' </s><br />
**but it seems to be useful : ''I've used Fail2Ban even with SSH password authentication turned off. It's still helpful for preventing huge error logs [https://news.ycombinator.com/item?id=8049916 via]''<br />
*We can find the following type of logs, reported at https://github.com/fail2ban/fail2ban/issues/1719 and addressed in 0.10 version<br />
