Does anyone have any suggestions on how to harden the server? I want to make sure that I have it secure. I know the we installed fail2ban, but it is not configured for the server applications. I have asked multiple times for a how-to or something to get it setup with the default installation, but nothing has ever been done. Is there anyone that has it that would be willing to share it?
Take a look at the fail2ban wiki, there you will find a lot of examples for varoius services. http://www.fail2ban.org/wiki/index.php/Category:Configuration e.g. pure-ftpd: http://www.fail2ban.org/wiki/index.php/Pure-FTPd Postfix: http://www.fail2ban.org/wiki/index.php/Postfix courier: http://www.fail2ban.org/wiki/index.php/Courier or dovecot: http://www.fail2ban.org/wiki/index.php/Dovecot
I have got some things working in fail2ban, Are there any suggestions to make it more secure? Just want to make sure it is good to go so that I can roll it out to clients. Thanks.
