We are asked as a hosting company to provide ddos protection. Is there a per server software we can install also what reasonably priced hardware options are there? We already have an optional per port Cisco ASA firewall, but anything additional?

this is always a compromise for an ISP as you are damned if you do and damned if you dont.

ISA Server and similar types of application gateways provide various forms of ddos protection from half scans, dns poisoning, fragmentation, floods etc as do the majority of layer 3 boxes such as PIX. The compromise is, for example, that most vpn's use fragmenting as do routers etc where the size of the MTU has been lowered from the standard.

Was there a particular form you had in mind?

Not really we are just looking to help protect the network and such. The Cisco ASA firewall does not seem to have IDS or really anything to do in case of DDOS. We host 100's of dedicated servers with all different operating systems and want to ensure that number one an attacked customer does not affect the other customers and number 2 that the attacked customer themselves has a remedy.

If you're concerned about DDoS Protection, you shouldn't be using a hosting company that doesn't provide it at the perimeter level.  You definitely don't want to be having your server itself handling this task since just the act of handling the DDoS Attack would produce it's own DDoS event.

I use The Planet for all my hosting, and they provide this as part of their service: http://www.theplanet.com/why_the_planet/security/

Can you give an overview of the perimeter environment?

You mention ASA (version?) but I assume with a sizeable profile like yours you must be using more than that.

I am not 100% sure as I am not a tech myself but i believe it goes

2811 cisco router
3550 cisco switch
Optional 5510 ASA firewall
then each rack has its own 3550 to control the bandwith allocated to each server

I believe that is correct, but if you need more i can get the info from one of the techs.

We were looking more like the below solutions

1. IntruGuard: Very cost effective. Has large userbase in Europe and US. Done using ASICs (custom hardware). Can withstand 2 Gbps throughput during worst attacks. Great reviews by analysts and users. Must look at this. Custom solution for DDoS, easy to use GUI. Google for Planeetta and MetaNet and you will find out why webhosts like the appliance. It is very easy to use. Easy to plug-in - bump-in-the-wire. Self-learning and adaptive as your business grows. Tolly Group has great things to say in their performance test for this box. Google Tolly+IntruGuard.

2. Top Layer: Has a user base. Combines IPS with DDoS. IPS is not so much essential in data center. More suited for enterprise deployment. You can cluster multiple of these boxes to get throughput. Costs becomes higher as throughput grows - obviously. Tested by Tolly Group. Google Tolly+Top Layer.

3. Riorey: DDoS solution. Appliance done in software - our current favorite
