Mysql Injection, how to prevent that ???

[josef]

I found that my forum many times become very slow and sometimes stop working while other times good and sometimes fast

I was checking the server which is powerful and dedicated server
but sometimes I found a high load on server which leads to hard browsing my forum

I found that load comes from mysql , I think someone trying to use mysql injection technique

I need proper procedure to protect my server/forum from any mysql injection

thanks

[josef]

is my question difficult or nobody has a solution for that ???

It's more likely to do with some add-on, plug-in or hack that you have installed that is causing too many queries or simply poorly written. Your forum is database run so naturally the load is from mysql

Did you find exactly what was being 'injected' at the time your load goes up?

mysql injection would cause serious if not major security issues. It shouldn't slow your forum down. What proof do you have?
