can you all techies suggest some solutions for joomla where lot of updates are involved on the website and configuration changes very frequent .
thanks in Advance
Updates for what? Joomla itself? Plugins/Extensions? Templates?
Updates frequently address security flaws.
If I recall correctly, Joomla has a wiki page explaining good security practices for a Joomla-powered website.
If that doesn't answer your question, can you elaborate? I'm not quite clear on what your question is.
