Forum security is always a top priority, it’s very important to protect your forum from MyBB security threats and avoid hackers and exploits. MyBB is a very secure forum, but just like all forum software, it’s not 100% perfect but it’s always improving. MyBB security should be your first concern when maintaining your forum.
Change the “admin” directory
By default the admin CP is at example.com/admin or example.com/forum/admin, this is a potential MyBB security issue since MyBB users will know where the admin directory is. You can change this, to do so here’s how.
1. Use your web host’s file manager (or an FTP program) and navigate to your forum’s root installation.
2. Rename the “admin” directory to something else. If you want a secure admin directory, use this strong password generator to generate a new name for you.
3. Go in the inc directory and edit the config.php file, find (should be on line 26):
$config['admin_dir'] = 'admin';
Change admin to your new admin directory, should be ‘change to your name’. Save changes.
Hide admin CP links
Also in the config.php file is an option to hide the Admin CP links, good for MyBB security and for after changing your admin URL directory in case if your administrator account gets compromised. Find:
$config['hide_admin_links'] = 0;
Change the “0″ to “1″, make sure you remember where your admin directory is.
