Keep your SMF version up to date and be on the lookout for security updates. You can also heed the following advice.

Password Security

Be sure to change your passwords often and don't use the same password for everything. You should have different passwords for each of the following.

  • FTP
  • Database (MySQL, PostgreSQL, or SQLite)
  • PhpMyAdmin
  • SMF Administrator Account

The most important password is the database password. This is the same password you use with PhpMyAdmin or any other database management control panel. This password is stored in the Settings.php file. Don't re-use this password for your FTP or your forum administrator account.

The best passwords:

  1. use letters, numbers, and special characters
  2. vary in upper and lower case
  3. don't use dictionary words or common names
  4. are not easy to guess
  5. are fairly long
  6. are something you can remember without needing to write it down

You can choose the minimum password strength for your users. The higher the level, the less likely that it will be brute forced.

Additional Security Tips for your forum

  • To keep anyone from taking over your forum, make sure your passwords are difficult to guess. You can do this by making sure your passwords do not relate to you (i.e. your spouses name), by mixing capital and lowercase letters with numbers, and by using special characters where applicable.
  • Frequently backup your database and FTP files and make sure you understand how to restore these backups.
  • Delete temporary files such as install.php, converters, recovery tools, etc.
  • Frequently check your error log for any suspicious or unusual errors.
  • Delete any login failures made by administrators from the error log.

Additional Security Tips to protect your users

  • Do not allow guests to upload executable files (extensions .php, .js..., etc.) -- guests could upload things you don't want on your forum.
  • Do not allow .exe or Flash files to be uploaded or displayed -- you don't want users to upload malware and persuade other users to download and open/execute it.

Backups with tilde (~)

Whenever some file is modified (by the mod operation for example) SMF creates a backup of it with a tilde (~). For example if some mod has modified index.template.php, SMF will create this file: index.template.php~. Notice that those files can be accessed through the browser, so it can be a possible vulnerability. To prevent these you can either disable this option in Administration Center or you can periodically delete them.
