In addition, sh404SEF can implement spam protection would be much harder to do at web server level.

Security includes many levels and is constant work. Some of the things you want to do:

  • running a wel configured and constantly updated web server software, or making sure your hosting company has an excellent rack record
  • using well-known and regularly updated extensions
  • constantly updating both Joomla! and the extensions you use

Flooding is the act of sending a lot of requests to a web server in order to make it slower and slower, and eventually take it down. sh404SEF can control the request rates from specific IP address and block access as early as possible. Though such protection is definitely best performed at web server level, sh404SEF implementation is easy to enable and works in multiple environment.


Protection of your site against the addition of malicious content in comments or forums can be improved by submitting incoming requests to Project Honey Pot for screening. This project constantly maintains a database of IP addresses known to belong to spammers.
