DDos attack?

Can DDos attack be prevented?

I am just curious like how come bigger website dont seems to be affected by ddos attack whereas my website has been attacked several times and my host was force to suspend my page.

I think this is not quite healthy as my user will soon stop visiting my site.

Any help?

Quality hosting companies can help prevent DOS attacks. I use the best in the business and it isn't 100% preventable, but they probably have stopped 99% of DOS attacks on my sites.

As history tells even people like Microsoft can still be brought down by DOS attacks. I don't think there is a 100% solution, but go with the best and you will be as close as possible to the best solution!

Thanks percentages,

My current host is a very cheap one but usually there is no problem except when my site starts to get more people then all the problems set in :(

Can DDos attack be prevented?

Short answer, no.

Like yourself, our web site has apparently been targeted for a denial of service attack, and on one occassion this was successful - the CPU load was so great, and the open file handles so many that I couldn't even log in to reboot!

You can reduce the success rate of attacks. In simple terms this involves buying more expensive hosting: a dedicated server, or even better load-balanced numerous servers, install a firewall and so on.

But I have no knowledge on dedicated server and how to set them up any suggestion for where to start?
