I wanted to use Kloxo as control panel, but I am quite worry about their security holes. Give any one give some some suggestions?

I wouldn't use Kloxo anymore due to its huge security holes etc. I am not really aware of any other free control panels but cPanel is so cheap these days or you could go with DirectAdmin.

I second this.
Also check webmin/virtualmin.

Due to the recent death of the owner of the company that makes Kloxo, which resulted in stalled development, there are a lot of security holes, so I wouldn't use it, neither would I use any other LxLabs products due to fear of hacker attacks.

There are alternatives out there. If you're going to host only one site on a server, you can use Webmin, which is quite good. If you're planning on doing hosting, cPanel is obviously the best, and DirectAdmin is also an alternative, although I strongly recommend that you go for cPanel, the industry's best control panel IMO.

I agree, if you already have a dedicated server see if they offer cPanel/WHM for an extra fee each month, if not look at an external licenses and get it installed on your server.

If you are providing hosting, cPanel/WHM is the norm.
